European Union is NOT increasing its emissions cut targets!

A number of newspapers and other sources, including The Times, are claiming this week that the European Union plans to increase the target for greenhouse gas emission cuts.

They report that a new target of cutting emissions by 30 per cent on 1990 levels by 2020, would be set and that this "would cost the EU an extra £33 billion a year by 2020".

Unfortunately, there is no truth in the story.

It is true that the European Commission has released a discussion document on the subject. But it is not, as The Times describes, a draft of a communication.

In fact, it explicitly says, "The purpose of this Communication is not to decide now to move to a 30% target: the conditions set are clearly not met."

The conditions remain the same as they were during the Copenhagen discussions in December. At that point the Commission said that it would move from the current target of 20% to 30% if everybody else committed to legally binding targets.

A spokesperson for the European Commission told us unequivocally that there are no plans to increase the target to 30%.

And currently the expectation is that a legally binding global agreement on reducing greenhouse gas emissions that would be a successor to the Kyoto Protocol will not happen, if it ever will, until mid-2011 at the earliest.

One might wonder why The Times is publishing so prominently - it was on the front page - a story like this. It contains the following paragraph:

"Business leaders fear that thousands of jobs could be lost and energy bills could soar. Carbon taxes on road fuel, heating and other sources of emissions could be introduced, with proceeds reinvested in renewable energy products."

Those who hold conspiracy theories about sceptics of climate change or the European Union might draw their own conclusions.

Will the "greenest government ever" preside over a 'blackout Britain'?

Before the election, the energy sector and the CBI by and large supported a policy programme that promised to "keep the lights on" and build a low carbon economy.

In five to ten years' time some current coal and nuclear power stations may have to be mothballed and there is now doubt that new nuclear power stations - which anyway would not be producing power for 15 years - will now be built, as Chris Huhne is known not to favour spending public money on them.

Add this to the cuts in both DECC's and Defra's budgets, and there is concern over a possible 'energy gap' looming.

The Energy Gap


“We need to explore alternative ways to combat this shortfall, such as building green oil power plants that  run off of sustainable oil, waste to energy systems that use all municipal solid waste (MSW) to generate electricity, which means there is no need for consumers to sort out their waste," said David Weaver, CEO of clean-tech company Ultra Green.
 
“These kinds of projects can be completed and producing power within five years. However, we need government support in the form of development grants and guarantees to accelerate the Britain’s renewables growth programme.”

We have already seen the loss of the Low Carbon Buildings Programme (LCBP) grants which will adversely affect the renewable heat sector (see my previous blog post).

An energy efficiency drive will reduce the rate of increase in demand for electricity.

But the sector requires immediately huge input in research, development, infrastructure and plant to quickly evolve a low carbon energy supply mix that meets future demand and bridges the energy gap.

Furthermore, the Queen's Speech contains bills that could have a negative impact on the UK’s energy and environmental sector.

Planning issues


A Devolution and Localism Bill, which will give local councils more control, could affect onshore renewable energy projects, by giving more power to NIMBYs.

Greg Clark, Minister for Decentralisation, said, "This Bill would reverse years of creeping state control and return power to people, communities and councils."

But the vast majority of councils which have rejected wind farm planning applications across the country have historically been Tory held.

One commentator, Howard Thomas, said on a government website that the coalition policy on ensuring 'sustainable development’ in planning is too vague and requires clarity. He called for "a clause in planning policy statements that every new development must not increase global-warming emissions and should save on them".

Loss of support


There's also the Public Bodies (Reform) Bill, which promises to do the opposite to the Localism Bill - centralise power by abolishing, merging or transferring quangos back into Departments.

Cutting quangos like The Carbon Trust, The Technology Strategy Board and its Knowledge Transfer Networks, and WRAP could seriously affect low carbon delivery objectives.

This could result in the loss of support for emerging tender shoots of nascent low carbon technologies.

Renewable energy grant scheme abruptly halted

The new Government's self-professed green credentials have come under question as a key grant scheme to put renewable heating into buildings has been stopped, to save a mere £3 million.

As of 6am on Monday, May 24th, the Government stopped taking fresh applications for grants for renewable heat systems. These were available under phase 2e of the Low Carbon Buildings Programme (LCBP).

The previous government’s intent was for the Renewable Heat Incentive (RHI) to take over from the LCBP. However there is now a gap of ten months before this goes live on April 1st 2011.

The LCPB's website says that "demand for grants has been unprecedented" and "we had very little unallocated funding remaining". It has therefore "been decided that by closing the programme now, these unallocated funds will contribute towards DECC’s overall savings".

The Solar Trade Association (STA) called it a "a retrogressive step" given "the relatively small budget required to support the LCBP".

DECC's cuts


The Department of Energy and Climate Change (DECC) said it had to make the cut to as its part of the £6bn cuts announced by George Osbourne and the Treasury. DECC is contributing £85m to this total.

About half this figure will come from efficiencies and other savings across our central spending and that of DECC's quangos. The other half comes from cutting or slowing down planned expenditure.

Effect on the industry


The declared "unprecedented demand" indicates a healthy sector and the public's desire to install microgeneration. Many social housing providers had significant plans to install renewable technologies such as heat pumps this year under the scheme.

These and other projects will now most likely be put on hold until the RHI comes in, although its exact form has yet to be confirmed.

Therefore the STA believes the ten month gap will cause a loss of jobs in the industry just at the moment the country wants to build capacity to install hundreds of thousands of renewable heating systems each year.

They called on the Government to find a small extra element in its budget to support the LCBP until the launch of the new incentive.

Howard Johns, Chairman of the STA said “This is very bad news for the solar industry, and a very disappointing move from the new coalition who are aiming to be the greenest Government ever. Once again been undermined for short term gain. At this point we have no idea what the RHI will look like and whether we will get it at all - effectively leaving our sector in limbo, and jobs at risk.”

Scott McLean, marketing director of Ownergy, commented: "The same happened to LCBP grants for renewable electricity installations ahead of the Feed-In Tariffs going live. We don't see it as any indication that the Renewable Heat Incentive is under threat."

The Low Carbon Buildings Programme


The LCBP grant programme has provided approximately 20,000 grants for the capital and installation costs of Microgeneration equipment of which, to date 11,000 have been for thermal technology (33% by value, 58% by number of installations). These have produced lifetime carbon savings of 300,000 tonnes of CO2.

Feed-In-Tariff for renewable electricity, introduced on 1 April 2010, mean that LCBP is no longer required for electrical microgeneration.

Green Belt campaigner and serial expenses abuser is new Defra chief

Caroline Spelman has joined the Cabinet as one of the few women members and is the new Secretary of State for Environment, Food and Rural Affairs - Defra.

She is MP for Meriden in the West Midlands and was once the Conservative party chairman (Jul 2007 - Jan 2009) but was removed during the expenses scandal.

During that time she was forced to apologise and pay back £9,600 of Commons allowances she 'inadvertently' misused to pay her children's nanny.

She also faced questions over her Commons expenses after pocketing £40,000 to run her Georgian mansion, claiming it was her 'second' home - allowing her to claim a small fortune of taxpayers' cash for cleaning and bills - while her husband Mark claimed it was his main home during his unsuccessful bid to become a Conservative MEP in this month's European elections.

And she overclaimed £200 for council tax which she has paid back. She said it was a 'one-off administrative oversight'.

More recently she has kept well within her expenses limit.

Previous attitudes

According to They Work For You, she has voted "very strongly" for laws to stop climate change and for replacing Trident - opposing her new Liberal Democrat colleagues.

She also appears to have been confused about what to do with the House of Lords having voted both "strongly" against removing hereditary peers from the House of Lords and "strongly" for a wholly elected House of Lords.

Previous posts she has held are:

• Shadow communities and local government secretary since Jan 2009

• Shadow secretary of state for communities and local government (Dec 2005 - Jul 2007)

• Shadow secretary of state for local and devolved government (Mar 2004 - Dec 2005)

• Opposition spokesperson, environment and shadow minister for women (Nov 2003 - Mar 2004)

• Opposition spokesperson, international development (Sep 2001 - Nov 2003).

Why has she been chosen for Defra?

Defra says that before then Mrs Spelman had an extensive career in the agriculture sector, with fifteen years in the agriculture industry and in-depth experience of the international arena, including as deputy director of the International Confederation of European Beet Growers and a research fellow for the Centre for European Agricultural Studies.

She has also authored a book on the non-food use of agricultural products.

She has a particular interest in preserving the "green belt" and housing.

On her website she writes "Striking an appropriate balance between the sustainance of rural character and the allowance of urban growth is a particularly sensitive issue in the Meriden Constituency.

"I was elected with a pledge to try and defend the Green belt and find myself in a pitched battle with the Government's planning rules."

She has campaigned against ‘garden developments’ or ‘garden grabbing’, arguing that “Currently, gardens are not protected as ‘green space’, but are treated as ‘Brownfield land’. What is needed is clarification of the definition of ‘Brownfield Land’”.

This is something that I blogged about last week, as an area that the coalition will need to look at.

She introduced a Private Members’ Bill in Parliament at the end of 2006 which would protect these green spaces and adjust planning rules so as to take this need into consideration.

Hopefully this is something she is in a better position to see through now.

With her obvious lack of experience and questionable judgment she will need to sharpen up quickly, before she gets eaten by farmers and waste disposal engineers.

New DECC man Huhne faces tough challenges

Chris Huhne is the new Energy and Climate Change Secretary. The Liberal Democrat, 55, MP for Eastleigh in Hampshire, was latterly the party's Home Affairs shadow, and previously its environment spokesman.

Simon Hughes, who was the LibDem's Shadow Secretary of State for Energy and Climate Change, might be surprised at the appointment.

But according to the website They Work For You, Mr Huhne does have a better record than Mr Hughes on voting to stop climate change.

Mr Huhne is particularly interested in tax reform, which might explain his appointment.

He has in the past advocated a switch from taxing employment and labour on to resource use, pollution and carbon emissions.

Together with Vince Cable, it's possible that they may influence George Osbourne's position in the Treasury on these crucial issues.

As we enter a period of public spending cuts the new coalition Government will have little room to bankroll environmental action, but instead has an opportunity to shift the burden of taxation to both protect jobs and the environment.

But there will be other tough decisions on policy.

During the election campaign, the Conservatives said they wanted to replace the Renewable Obligation and system of Renewable Obligation Certificates (ROCs) with an extended feed-in tariff scheme.

This could mean considerable uncertainty for large-scale renewable energy projects investors, such as wind farms, which are currently being planned based on the returns they could realise through the ROC system.

Huhne will have to spell out very soon what he plans to do about this.

In addition, the Tories are for nuclear and the LibDems against.

Apparently the Tories are giving their coalition partners the option of abstaining on any Parliamentary vote on nuclear power, leaving them have to get Labour on board to secure a majority, as well as promising not to spend any public money on the technology.

This could mean that new nuclear build faces an uncertain future.

Will a hung Parliament be good for the environment?

Now that we know there is to be a hung Parliament, the stage is set for much horse trading on environmental issues between the three main parties.

And, now that Caroline Lucas has become the first Green Party MP since Cynog Dafis won his seat in the '90s on a joint Green-Plaid Cymru ticket, it will be fascinating to see if she succeeds in raising the profile of environmental issues.

She deserves huge congratulations, as she has won this on the back of many years of dedication and hard work as a Green MEP.

On the whole, the Liberal Democrats hold the greenest of policies amongst the main three, but if, as seems likely, they attempt to forge an alliance with the Conservatives, then it will be very interesting to see how a party that is against nuclear power and for onshore wind can get on with one that opposes these policies.

Let's take one topic and see what could happen: planning and housing.

Where both Tories and LibDems agree, and differ from Labour, is in a promise to abolish regional planning, including regional spatial strategies.

Although the Liberal Democrat Policies for the Environment election document had little to say about spatial planning it did pledge to abolish the Infrastructure Planning Commission and return planning, including housing targets to "local people", something the Tories might agree with.

A Conservative government would pay councils to release land for housing by matching pound-for-pound the council tax receipts they receive from new housing, and the LibDems could support that.

But the Tories have no target for housing on brownfield land to protect greenspace, unlike the Labour Government, which set one at 75%.

Labour promised to maintain the 60% brownfield and minimum density targets for housing in its election document A Green Future for All, and was the only main party to say it would enforce greenfield land releases, according to its Plan for Housing.

Labour also promised promise to end so-called "garden grabbing" by defining them as greenfield sites in "planning  law" so they cannot be so easily built over.

The Tory document, Modern Conservatism: Our Quality of Life Agenda launched during the campaign represented a very pale green version of John Gummer's 2007 quality of life commission document which promoted a wide range of radical Smart Growth policies.

One thing seems certain: the prospect of a hung Parliament will act as a brake on the deregulatory excesses of the right that historically have not boded well for the environment - which, naturally, does not have a vote.

How to vote tactically for a greener new government

Thanks to Frannie Armstrong for this!

A Tory government would be a disaster for the environment and climate change.

Their candidates rank climate change as 19th out of 19 most important issues and want to decrease onshore wind and increase North Sea oil drilling. Their party is riddled with climate sceptics (with one even rumoured to be lurking in the shadow cabinet).

There are six seats (Battersea, Brighton Kemptown, Calder Valley, Colne Valley, Hove and Stroud) where the Green vote is large enough to give a Labour seat to the Tories.

There are at least three (including Carshalton and Wallington, Dorset West and Torridge and West Devon) where it would either give a Lib Dem seat to the Tories or prevent the Lib Dems from taking one from them.

So we urge everyone who understands the precipice on which we all stand to be highly tactical with their vote:

  • If you live in a hope-in-hell constituency, vote Green: Caroline Lucas in Brighton Pavilion (now the bookies' favourite), Tony Juniper in Cambridge, Adrian Ramsay in Norwich South and Darren Johnson in Lewisham Deptford.
  • If you're in a Labour-Tory marginal, steel your environmentalist's heart and vote Labour rather than Green
  • If you're in a Lib Dem-Tory marginal, vote Lib Dem rather than Green
  • If you're in a Labour-Lib Dem marginal, vote for Labour, with an eye on helping stop Clegg siding with the Tories if there's a hung parliament. (Clegg said last week that he'd be happy to work with the Tories as long as they concurred on four policies - fairer taxes, a shake-up of the education system and economic and political reform. Nothing else important, Nick?)
  • If you're in a safe seat for any of the three main parties vote Green to add one more to the Greens' total and strengthen the case for proportional representation next time.

Meanwhile, till Friday morning, you can watch The Age of Stupid free for 48 hours - from now till the polls close tomorrow night.

Tories are the most un-green of the parties, LibDem greenest

Of the mainstream 3 parties, the LibDems have the greenest policies and candidates followed by Labour with the Tories trailing badly.

FoE supporters contacted their parliamentary candidates to ask them to support four pledges:
  • a strong and fair international agreement to tackle climate change;
  • a local carbon budget for every local authority;
  • investment in switching to a low-carbon economy;
  • and tackling the major greenhouse gas emissions and deforestation caused by the UK's dependence on imported feeds for livestock.

The results were:
  • Less than 1% of Tory candidates agreed (4),
  • 182 of the 446 Lib Dems agreed;
  • 96 of the 479 Labour candidates agreed


Andrew Smith, former Labour minister and candidate for Oxford East, said: " A Tory government would threaten the low-carbon transition: sceptic MPs, no to onshore wind, on the fringes in Europe."

The Conservatives also plan to increase oil drilling in UK waters.

According to a green paper on energy policy published in March, a future Conservative government would "implement a tax regime that offers sufficient incentive to keep existing fields open as long as possible, and which also makes new exploration on the UK continental shelf attractive".

It added: "In addition, we will improve the incentives for exploring and developing marginal fields ... opening up new areas, including in the seas west of the Shetlands."

When questioned by George Monbiot, Greg Clarke, the Tory energy shadow, could see no contradiction between this stance and having a carbon emissions reduction target.

In this video he comes across as woolly and superficial in his thinking.

In addition, the Tories want to scrap many quangos and let ministers make more decisions.

This could mean a severe shrinking of anti-pollution measures resulting in a more polluted country.

When I asked Central Office to deny categorically that the Tories would not scrap the Waste and Resources Action Programme or the Environment Agency, they could not do so.

Finally, the LibDems are the only party wanting to scrap nuclear power and Trident.

Use your vote wisely.

Grid connection and intermittency of renewable energy

It's still said that when the wind doesn't blow you need other sources of power, so wind farms are really a waste of money.

This topic - grid integration of renewables and variability - has been extensively investigated.

One conclusion - from the UK Government report quoted below - is: "For penetrations of intermittent renewables up to 20% of electricity supply, additional system balancing reserves due to short term (hourly) fluctuations in wind generation amount to about 5-10% of installed wind capacity."

Peter Freere, formerly an engineering professor at Monash University in Australia says:

"It is correct that in normal electric grids (without energy storage - eg pumped storage, charging electric cars, etc.), a single wind farm would not work well on its own and some conventional energy sources are also required.

"The same applies to the conventional energy sources, especially nuclear, whose response time is so slow that they must have a fast responding generation system in parallel.

"It is also true that due to the large sizes of modern generators in conventional systems (eg. 500 MW per generator), to allow for maintenance and breakdowns, it is necessary to have a complete spare generator ready to take over when another stops working (for whatever reason)."

"Hence the risk with wind farms is not so great - no more than many conventional systems."

The largest study on grid integration was done in Germany by DENA. The gist is that investment in the grid will be necessary to integrate the new renewable generation needed meet the German target of 20% of supply from renewable energy by 2020. The investment required is less expensive than additional grid expansion if new central-station plants are built, and this investment will result in making the grid more stable with or without the renewable generation.

A March 2006 UK Energy Research Centre report analysed the results of 200 studies on the grid integration of intermittent renewables. The following are excerpts from the summary of The Costs and Impacts of Intermittency: An assessment of the evidence on the costs and impacts of intermittent generation on the British electricity network. Below are its conclusions:

  • It is sometimes said that wind energy, for example, does not reduce carbon dioxide emissions because the intermittent nature of its output means it needs to be backed up by fossil fuel plant. Wind turbines do not displace fossil generating capacity on a one-for-one basis. But it is unambiguously the case that wind energy can displace fossil fuel-based generation, reducing both fuel use and carbon dioxide emissions.

  • Wind generation does mean that the output of fossil fuel-plant needs to be adjusted more frequently, to cope with fluctuations in output. Some power stations will be operated below their maximum output to facilitate this, and extra system balancing reserves will be needed. Efficiency may be reduced as a result. At high penetrations (above 20%) energy may need to be 'spilled' because the electricity system cannot always make use of it. (However it is hoped that in the future elecric cars will be charged sing this energy.) But overall these effects are much smaller than the savings in fuel and emissions that renewables can deliver at the levels of penetration examined in this report.

  • None of the 200+ studies reviewed suggest that introducing significant levels of intermittent renewable energy generation on to the British electricity system must lead to reduced reliability of electricity supply2. Many of the studies consider intermittent generation of up to 20% of electricity demand, some considerably more. It is clear that intermittent generation need not compromise electricity system reliability at any level of penetration foreseeable in Britain over the next 20 years, although it may increase costs. In the longer term much larger penetrations may also be feasible given appropriate changes to electricity networks.

  • The introduction of significant amounts of intermittent generation will affect the way the electricity system operates. There are two main categories of impact and associated cost. The first, so called system balancing impacts, relates to the relatively rapid short term adjustments needed to manage fluctuations over the time period from minutes to hours. The second, which is termed here 'reliability impacts', relates to the extent to which we can be confident that sufficient generation will be available to meet peak demands. No electricity system can be 100% reliable, since there will always be a small chance of major failures in power stations or transmission lines when demands are high. Intermittent generation introduces additional uncertainties, and the effect of these can be quantified.

  • System balancing entails costs which are passed on to electricity consumers. Intermittent generation adds to these costs. For penetrations of intermittent renewables up to 20% of electricity supply, additional system balancing reserves due to short term (hourly) fluctuations in wind generation amount to about
    5-10% of installed wind capacity. Globally, most studies estimate that the associated costs are less than £5/MWh ($0.0087/kWh) of intermittent output, in some cases substantially less. The range in UK relevant studies is £2 - £3/MWh ($0.0035-$0.0052/kWh).

  • Unless there is a large amount of responsive or controllable demand, a system margin is needed to cope with unavailability of installed generation and fluctuations in electricity requirements (e.g. due to the weather). Conventional plant - coal, gas, nuclear - cannot be completely relied upon to generate electricity at times of peak demand as there is, very approximately, a one-in-ten chance that unexpected failures (or "forced outages") in power plant or electricity transmission networks will cause any individualconventional generating unit not to be available to generate power. Even with a system margin, there is no absolute guarantee in any electricity system that all demands can be met at all times.

  • Intermittent generation increases the size of the system margin required to maintain a given level of reliability. This is because the variability in output of intermittent generators means they are less likely to be generating at full power at times of peak demand. The system margin needed to achieve a desired level of reliability depends on many complex factors but may be explored by statistical calculations or simplified models. Intermittent generation introduces new factors into the calculations and changes some of the numbers, but it does not change the fundamental principles on which such calculations are based.

  • Intermittent generators can make a contribution to system reliability, provided there is some probability of output during peak periods. They may be generating power when conventional stations experience forced outages and their output may be independent of fluctuations in energy demand. These factors can be taken into account when the relationship between system margin and reliability is calculated using statistical principles.

  • Capacity credit is a measure of the contribution that intermittent generation can make to reliability. It is usually expressed as a percentage of the installed capacity of the intermittent generators. There is a range of estimates for capacity credits in the literature and the reasons for there being a range are well understood. The range of findings relevant to British conditions is approximately 20 - 30% of installed capacity when up to 20% of electricity is sourced from intermittent supplies (usually assumed to be wind power). Capacity credit as a percentage of installed intermittent capacity declines as the share of electricity supplied by intermittent sources increases.

  • The capacity credit for intermittent generation, the additional conventional capacity required to maintain a given level of reliability and thus the overall system margin are all related to each other. The smaller the capacity credit, the more capacity needed to maintain reliability, hence the larger the system margin. The amount by which the system margin must rise in order to maintain reliability has been described in some studies as "standby capacity","back-up capacity" or the "system reserves". But there is no need to provide dedicated "back-up" capacity to support individual generators. [Emphasis added] These terms have meaning only at the system level.

  • This assumes around 20% of electricity is supplied by well dispersed wind power. Current costs are much lower; indeed there is little or no impact on reliability at existing levels of wind power penetration. The cost of maintaining reliability will increase as the market share of intermittent generation rises.

  • The aggregate 'costs of intermittency' are made up of additional short-run balancing costs and the additional longer term costs associated with maintaining reliability via an adequate system margin. Intermittency costs in Britain are of the order of £5 to £8/MWh ($0.0087-$0.0139/kWh), made up of £2 to £3/MWh from shortrun balancing costs and £3 to £5/MWh from the cost of maintaining a higher system margin. For comparison, the direct costs of wind generation would typically be approximately £30 to £55/MWh ($0.052-$0.0958). If shared between all consumers the impact of intermittency on electricity prices would be of the order 0.1to 0.15 p/kWh ($0.0017-$0.0026/kWh).

The cost-effectiveness of low or zero carbon energy generation

This update is following from my previous blog and George Monbiot's attack on feed-in tarriffs and responses to it.

Reliable independent figures on cost-effectiveness of low or zero carbon energy generation based on real monitored examples are yet few, and I'm trying to collate them, because this kind of evidence is what we need to help determine policy.

Crucially, page 37 of the 2009 impact assessment of the Community Energy Saving Programme (CESP) (which places an obligation on energy suppliers and electricity generators to meet a CO2 reduction target) ranks the effectiveness of non-large-scale generation measures in kgCO2 per pound sterling spent as follows:

1 Existing community heat to CHP 88 (kg CO2 score per £ spent)
2 Electric to community CHP 39
3 Wood pellet boilers (primary) 24
4 Micro Hydro (0.7kWp, 50% LF) 16
5 Ground source heat pumps 14
6 Air source heat pump 13
7 MiniCHP (revised) 9
8 Mini-wind 5 kW, 20% LF 4
9 Solar Water Heater (4m2) 4
10 Photovoltaic panels (2.5 kWp) 3
11 Micro Wind (1 kWp, 1% LF) 0

From this it is quite glaringly obvious that for both heat and power the community scale is by far the most efficient level for interventions. Right at the bottom are the single-dwelling only solutions (I dispute the figures for wood pellet boilers since data on their carbon content is disputed) except where hydro is available (not many places).

The Electricity and Gas (Carbon Emissions Reduction) Order 2008 (CERT) looked into the cost and carbon reduction effectiveness of various measures. The document Explanatory Memorandum To The Electricity And Gas (Carbon Emissions Reduction) Order 2008 contains a further Evidence Base.

In this community CHP with woodchips comes out at nine times more cost-effective in ££ per tonne of carbon saved than solar water heating and about the same as ground source heat pumps.

The figures are (- with suppliers’ cost to save one tonne C02 (£/tC02) for the Priority Group):
1 Community heating with wood chip 3
2 Ground source heat pumps 42
3 Wood chip CHP 49
4 Wood pellet boilers (primary) 58
5 Micro Hydro (0.7kWp, 50% LF) 60
6 Log burning stoves 110
7 Mini-wind 5 kW, 20% LF 125
8 Wood pellet stoves (secondary) 126
9 mCHP 176
10 Photovoltaic panels (2.5 kWp) 218
11 Solar Water Heater (4m2) 346
12 Micro Wind (1 kWp, 10% LF) 685
13 Community ground source heat pumps 697

The above underscores that renewable energies are frequently site-dependent and sensitive to economies of scale, because you have to cost the whole system.

Only 2% of UK homes can have a small wind turbine. This Energy Saving Trust report suggests the best sites and how to pick them.

Solar electricity


In my previous blog I link to actual surveys of real PV installations and the figures show that they do not generate sufficient power in the UK when we need it for the reason that there is not enough sunshine in the winter - unless you have a huge array, which is currently very expensive.

If PVs could become as cheap as a low-e coated window unit, with spray-on or printed nano-scale circuitry or similar it might be worthwhile. This is a technological advance not a deployment advance. They would also need to capture a greater range of frequencies of light.

I would suggest that the standard for measuring and marketing the rated output of a panel or a system is changed to make it more realistic and easier for buyers to understand. As discussed in the blog above, the test conditions are way different from European field conditions and led to unreal expectations, or to potential obfuscation by the industry/ unscrupulous installation companies.

Conclusion



All of this suggests that while renewable heat can work on a community level, only CHP can universally provide electricity, whatever the power source, and then not that much in relation to demand since there is a limit to the available waste, waste heat and biomass.

Therefore we have to conclude that for renewable electricity generation larger scale wind and marine power are what is required at a massive scale. Of these, only wind is currently cost-effective and that is why it is being aggressively pursued offshore and onshore.

Does PV - solar electricity - work in the UK?

The Government's Feed-in-Tariff (FIT) programme - energy cashback - will soon give subsidies for householders installing renewable energy in their homes.

George Monbiot told me last night he's going to publish tomorrow a critique of them (it's online now, here), arguing that when subsidising solar electricity (photovoltaic/PV) panels they are a waste of money and a rip-off to taxpayers.

As I have in the past campaigned for FITs, I was initially taken aback. But then I recalled I'd looked into the cost-effectiveness of PV systems before and agreed.

The truth is they do have very long cash payback times, even with a subsidy, which is an artificial way of reducing payback and doesn't reduce its actual real-world cost.

The question then arises - shouldn't we spend the money on other technologies which can have the same impact on reducing carbon emissions but more cost-effectively? George quotes the same McKinsey report comparison table Ive used before and which is in the Stern Report, to indicate which technologies do offer value for money.

What's the evidence for saying they are a waste of money?



Firstly: Here are the results of a 2006 study from Bartlett School of Graduate Studies, University College London:

This paper compared two solar systems, an actual building integrated, photovoltaic roof (BIPV) and a notional solar thermal system for a residential block in London, UK.

The carbon payback for the solar thermal system is 2 years, the BIPV system has a carbon payback of 6 years.

Simple economic payback times for both systems are more than 50 years. Calculations considering the current UK energy price increase (10%/yr), reduce the economic payback time for the PV roof to under 30 years.

The costs to reduce overall carbon dioxide emissions using a BIPV roof are £196/tonne CO2, solar thermal individual systems at £65/tonne CO2 and community solar thermal at £38/tonne CO2.


Secondly: A BRE / DTI 2006 UK Photovoltaic Domestic Field Trail (PV DFT) made recommendations on installing PV but did not even look at payback.

Thirdly: Here's something I wrote in my forthcoming book on environmental refurbishment that was taken out by an editor:

Photovoltaics would not need the high level of financial support that the technology clearly does if there wasn’t a problem with generating enough power in extreme latitudes to justify their installation.

Many people have had their enthusiasm for photovoltaics curbed when they find out exactly how much power they can expect to generate for their cash. Therefore it is important to be quite clear on this: you are unlikely to generate more than a fraction of what you need and if you’re looking for quick paybacks, forget it.

The best way to demonstrate this is through a worked example.

Lesson 1:
Solar panel manufacturers quote figures for the “peak power” and “installed capacity” of their products. According to industry standards these are the amounts of electrical output in watts that they would generate if one kilowatt per square metre of the sun’s energy were to fall on them. But how close is this to the amount of sunshine at your location? These figures can be found out from the same source on insolation given in the section on solar water heating. For most of the latitudes that cover England and Wales, the summer insolation is a fraction of that figure. Even Europe’s sunniest place, Limassol in Cyprus, only gets 325 W per square metre. London gets 198 and Edinburgh 172 in July. In December, the figures are 96, 22 and 13 respectively. So in the winter, it’s a lot less -- and that’s when you need more power because the lights will be on for longer.

On average, Edinburgh receives just 9% of the solar energy required by the panel to generate what it says it will on the box.

Lesson 2: Suppose you installed 30m2 of panels that were quoted by the manufacturer as having a peak power or installed capacity of 5.7kWp. Suppose they were installed in London, which has an average insolation figure over the year of 109W/m2. In that case you wouldn’t get 5.7kW averaged over the year, but 0.109 x 5.7kW = 621W. However that is the average figure.

In darkest December they were generating just 125W, or enough to power 10 low energy light bulbs. In fact it might be even less than this, because of shading, downtime and other system inefficiencies.

Lesson 3: How much would this cost and what would your payback be? Here are some figures from 2004 for an installation on the roof of The Insolvency Service, in Bloomsbury London. (There aren’t that many case studies where the figures are all available -- this one comes from a UK government report - Large-Scale Building Integrated Photovoltaic Field Trial: URN Number 07/1316, BERR, 2007:

Size  Annual Output Project Cost Cost per peak W  Cost per kWh Payback time

kWp MWh/year £ £/Wp p/kWh (years)

25.4 11.8 318,760 12.6 108.2 237

237 years payback? This is a good example of how not to do it - and perhaps ironic given the purpose of the institution (if we did this we would go bankrupt).

The best performance figures in the report come from a water park in the Cotswolds.

These are from 300 building-integrated monocrystalline modules rated at 85W on a 150m2 sloping roof, with a yield of 51kWp. The system cost €397,500 in 2003 and the following year generated 44.3MWh. The figures in the report are:

51.0 42.8 2 65,000 5.2 24 .8 54

54 years is still a long time to wait to get your money back, especially when the modules only came with a 20 year warranty from BP. And 24.8p per kWh is still twice the current average electricity price.

(These examples illustrate how to work out PV systems’ cost effectiveness. To work out how much carbon emissions they save, simply multiply the megawatt-hours by the carbon dioxide emissions figure given for fossil fuel electricity, which presumably the panels will displace, given on page x - 550 kg/MWh.)

Lesson 4: Although the figures from the field trials report a mean/peak power ratio of over 7%, equivalent to an annual yield of over 610kWh/kWp, if we accept a grid-purchased electricity price of £0.114/kWh (the 2008 UK average), and require a 5 year payback period, the break-even cost of a PV system - the total installation cost per peak watt - is £0.35/Wp.

But the UK Energy Saving Trust, in its brochure on solar electricity published in 2007, quotes installation prices for domestic rooftop PV of £5–£7.50/Wp. This seems a bit steep, but: it is 14–20 times higher than the break-even value.

And you’re only generating a fraction of the power you need.

Renewable domestic heating

On a domestic level, the Government has committed to support domestic micro-CHP with £2,300* cash support. But this does not apply to district level heating schemes.

This article looks at both ideas, carbon impacts and support in the UK.

District heating


District heating is more carbon-efficient than heating individual homes where the density of accommodation is high enough. The example in Southampton is often cited.

The idea was part of last year's DECC Heat and Energy Saving Strategy Consultation. It did suggest support for these schemes.

The conclusions were published in August 2009. We're still waiting to see what the Government decides to do.... and will probably wait for some time as there is an election on.

District heating is recommended to the Government by this month's report from the Green Building Council. This says:

1. Public sector buildings should be required, where available and viable, to connect to existing or planned community heat networks, to provide an ‘anchor load’ of demand, and large businesses should be encouraged to do the same.

2. The ‘allowable solutions’ mechanism should be used as a way of providing additional ring fenced capital to support the delivery of heat infrastructure. Government has said that developers will be able to invest in so-called 'allowable solutions' in order to meet the required standard when constructing new zero carbon buildings.

It says nothing about existing non-public buildings though.

Neither is district heating part of the current renewable heat consultation. This scheme, which is due to start in April 2011, will subsidise a rapid increase in the number of homes and offices heated by woodfuel, biogas, solar thermal, heat pumps and waste-to-energy technologies. The deadline for responses to this consultation is Monday 26 April so do have your say.

District heating systems are ideal if a whole street, area or block of flats is to be renovated. Economies of scale make this form of heat and power delivery the cheapest on a per-household basis, and by far the most carbon-efficient, if low carbon fuel sources are specified.

A district heating scheme in Southampton, England, serves many residential developments from gas-fired CHP and geothermal energy, saving 11,000 tonnes of carbon a year and benefiting residents with a service price 5 per cent less than the market rate.

Systems are most efficient when servicing both homes and businesses or premises used during the day, as the two heat loads throughout a 24 hour period suit the continuous running required of a large plant.

District CHP plants may utilize fuel sources from waste to biomass, as well as geothermal where it is available. They work best where buildings are close together. A not-for-profit energy service company is usually formed to manage the system.

Micro-CHP


Micro-CHP – combined heat and power – is a nascent technology of small units for individual homes, typically the size of a fridge. They run on natural gas to produce up to about 10kW of power.

The current crop of models are based on the Stirling engine, Organic Rankine Cycle (ORC) or internal combustion engine. The first two have high thermal efficiency and output but low electrical efficiency (10 per cent) – and this is a sticking point.

Electricity output is around 1.1kW, enough to maintain back-up power in the event of a power cut or boil a kettle. A 1kWe (1kW electrical power) model from Honda called Ecowill has sold well in Japan.

A 2007 trial by the UK’s Carbon Trust concluded that micro-CHP can cut electricity bills and overall CO2 emissions by 15–20 per cent when they’re the lead boiler in larger contexts like care homes, district schemes, apartment blocks and leisure centres.

The best individual home for them therefore is a medium-to-large, moderately well-insulated one, maybe with solid walls, solid floors and no loft space that is harder to insulate well and has a relatively large heat demand.

Here, micro-CHP units can potentially deliver carbon savings of 5–10 per cent – fewer than a condensing boiler, since capacity is likely to be best matched to demand, for both heat and power.

Payback can be as little as five years. But they offer limited benefits for smaller and newer dwellings.

The key to success is matching the thermal output to the building’s pattern of use so that they operate not intermittently but for many hours at a time, making the value of electricity generated pay for the marginal investment in as little as three years in a typical family home.

It therefore works best with a buffer storage tank to save the surplus heat for later.

Grid connection for electricity export is going to be crucial to micro-CHP’s widespread acceptance. On average, half of all electricity generated by a typical 1kWe micro-CHP device is exported to the grid as it’s not needed at the time.

Reliability is also a key issue – service agreements will be essential. So homeowners shouldn’t yet trade in their condensing boilers, which have about the same overall heating efficiency – 90 per cent – without also producing electricity, but they might keep an eye on developments.

Superinsulated homes will have to wait until the next generation of machines, based on fuel cells. These generally come in two types – proton exchange membrane fuel cells (PEMFCs) and solid oxide fuel cells (SOFCs).

They have a heat to power ratio that is approximately equal so for example they could produce 5kW of heat and 5kW of electricity.

Support for micro-CHP


Under the Feed-in Tarriff scheme, from the 1st April 2010, microCHP units with a capacity below 2kW will receive 10p per kW hour generated, for a period of ten years. This tariff is available for the first 30,000 microCHP installations. A review will take place when 12,000 units have been installed.

However the Government has not followed through on commitments made in the Energy Act to support miniCHP units of up to 50 kW capacity.

* - based on 10p generation tariff and assuming a 3p pence export rate. Assuming annual generation of 2000 kWh and 50% export. Assuming import electricity price of 14p kWh-1. The total income paid to a generator over a 10 year FiT period would be £2,300 over full period of 10 years. Annual figure therefore of £230.

The Feed-in Tariff (FiT) scheme is the first phase of the Government’s Clean Energy Cashback programme - see the Energy Saving Trust website for details.

What is the most carbon efficient heating?


An independent survey conducted by the UK Energy Efficiency Partnership for Homes which looked at the carbon impact of different domestic heating and hot water systems in both houses and flats concluded that the following performed best, all other things being equal (figures in kgCO2/m2/yr):
• community heating and CHP, fuelled wholly or mainly by biomass - 4.15
• community heating without CHP fuelled wholly or mainly by biomass - 7.11
• wood burning boilers - 10.02
• wood burning boilers with solar water heating panels - 10.09
• ground source heat pumps with low temperature heat distribution/emitters (e.g. underfloor heating) - 20.83
• solar water heating panels in conjunction with gas boiler systems - 21.98

Green gadgets - do people care?

A new survey 'Is There Any Hope For Green Gadgets?' into attitudes towards buying more eco-friendly products makes depressing reading.

However, its question 'What would make you more 'green' with gadgets?' (an awkward question anyway) is loaded with its multiple choice answers.

56% of people said tax rebates and cash incentives.
47% of people said easier ways to recycle gadgets.
29% said information to educate them about what they can do to help.
17% said new laws would make them more green.

Of course people are going to answer tax rebates and cash incentives! and not like new laws.

In fact it is environmental legislation that drives companies to make changes in their product standards, save resources, and indeed develop international standards like Energy Star.

Legislation should actually remove inefficient and wasteful goods from the market. If the choice is taken out, so you can't buy them, there's no need for consumers to feel they have to be bribed or plagued by guilt to help nature.

This is happening with old fashioned light bulbs. It should happen with all wasteful gadgets.

But there is another point. Gadgets are becoming more efficient. But we are not using less energy. This is because we are buying more gadgets.

There's only one real answer - to buy less.

Bloom box mania - behind the hype

Lot of fuss in the States about the 'Bloom Box'. Wild claims and fantasy. Let's just set it straight:

What is it? = a solid oxide fuel cell

What does it do? = convert one type of energy - hydrocarbon chemical - into another - electricity

Is it renewable? - Depends what you charge up the fuel cell with. As with electric cars, think beyond the battery. It runs on ethanol, biodiesel, methane or natural gas. At least one of these (the last) is not renewable. Ethanol can be distilled from plants. Methane can be tapped from landfill/sewage etc. Whether the first two are sustainable (the real question) depends on the original bio-material - plenty of controversy about biofuels right now. Indonesian palm oil? No thanks. Displacing food-growing? Also no. High fertiliser and pesticide input? (ie fossil fuel and pollution) Also no.

Is it efficient? = The unit is not even a mini-chp (combined heat and power) plant - so the heat output is wasted. Solid oxide fuel cells have an efficiency of around 50% - better than a conventional power plant (32%) but CHP is over 90%.

Should I buy one? = You're better off with a mini-CHP and using the heat. These're also fridge-sized, will heat your building a well as power it, are more efficient when grid-connected, and will be mass market in a couple of years. They are already fairly big in Japan.

Weather, climate and complexity - where the sceptics don't get it

So why have there been cold snaps in Washington and London if the planet is warming?



Climate change marks a transition between a (recent past) stable period of predictable global climate and another, as yet unknown, one in the future, where temperatures on a global average will be higher.

When any system moves from one stable position to another there is always a period of instability and turbulence in between.

The study of this is called complexity theory and uses mathematical models developed from non-linear chaos theory.

A parallel analogy is, for example, an aeroplane changing its angle of flight from level (stable) to vertical (falling from the sky, but still linear). In between it will stall, and this is when occupants would feel their ride to be very bumpy.

Transferring the analogy to weather - weather is a local variant of climate.

Instability in the climate will therefore result in local 'bumpiness' - unusual and extreme local weather conditions. In some places this will mean occasional extremely cold, stormy or hot weather.

To think that an episode of local cold weather means that the whole world is getting colder, or even not warmer, as climate sceptics do, is almost like thinking that if the lights fail in your building, it's the same all over the world.

After the disappointment of Copenhagen - where now?

It depended what, or where, you were reading, how December's COP-15 talks were spun to you. Hailed as a success in the US and the Indian Times, they were marked as a failure in Europe.


For those who saw failure for the UN Climate Change conference to conclude with a legally binding and effective deal, the blame lay either with China or the US.

Over in the US, the pro-climate action body World Resources Institute was among those who blamed Somalia and other developing nations most threatened by climate change for nearly scuppering the deal, which they claimed was "rescued" by Obama.

Meanwhile, Lumumba Di-Aping (Sudanese leader of the G77) compared the Copenhagen Accord proposed to the Holocaust and to asking African people to sign a suicide pact.

Tuvalu and other threatened states remain very bitter about the lack of transparency - the text of the Accord had been agreed before midnight by a small group of countries (including China, Japan, India, Brazil, the US and EU) and brought to the plenary.

The EC identified the biggest challenge as finding a way to share global emission reductions between rapidly-developing countries, like China and India, and more industrialised regions, like the US and Europe, responsible for the bulk of historical CO2 emissions. It said it was 'disappointed' by both the Chinese and Ameican pledges at Copenhagen.

After the dust has settled, it does seem that China was more obstructive than any other significant player.

So, after two years of wrangling and stalling, we must now wait for further meetings and talks this year to (maybe) declare a legally binding document, with firm targets.

What was decided at Copenhagen?


A small group of nations negotiated the Copenhagen Accord. However, they are responsible for 80% of emissions, and they promised immediately $28bn of short term support and $100bn/yr from 2020.

When this document was taken to the Plenary on the floor, there wasn't final agreement, but UNFCCC Executive Secretary Yvo de Boer claims there was "overwhelming support", citing the 120 heads of state who came to Copenhagen. But in the end, the Accord was only "noted" by those countries.

Nevertheless, de Boer argues, "it is a political tool we will deploy to resolve remaining issues over the coming year, e.g. on financial support and what developing contries need to do and what bodies need to be established".

The Accord contains no mention of targets for 2020 or 2050, but there is an "intent" to work towards a maximum 2 degree Celsius limit on average global temperature rise.

The document mentions pledges already made by some parties. Other countries can write their intentions into the scheme in the document before 1 February.

Before Copenhagen, financial pledges were made by individual countries and these are in the Accord.

For long term finance: $100 bn each year by 2020 was promised, from public and private sources.

For short term finance (2010-12) the following was promised:

$30 billion - EU

$11 billion - Japan

$3.6 billion - US.

Verification of countries' claims for emission reduction was a contentious issue: large developing countries must report their emissions every second year. There will be some kind of international surveillance but at the same time "respecting national sovereignty". There will not be a review of progress until 2015 to determine if all this action is urgent enough. We already know it is not.

In fact, de Boer said on 20 January that the failure at Copenhagen "makes our task more urgent, as the window of opportunity is closing faster than before". He acknowledged that in "financial, human and economic terms the challenge requires much greater investment". Nevertheless he acknowledged three outcomes:

1. the challenge is being met at the highest levels of government

2. it reflects a gobal political consensus

3. at negotiations away from the camera, a full set of decisions was brought to conclusion.

However, the REDD framework was not finalised at Copenhgen, so REDD money (for forest preservation) cannot be distributed.

The UN is looking forward


The names of those countries who agree with the Accord will be published in the Accord below the title.

De Boer has given countries a deadline of 31 January to be on this list, which will be updated on an ongoing basis on the UNFCCC website.

He was careful to say that signing it meant they do not "adhere" to its contents but agree to "be associated".

They can opt to adhere, or, if they are industrialised countires, to indicate the targets they will set, or, if developing countries, say what actions they will take. "The Accord is a living document" he said. No one is 'bound' to the Accord.

It will be used to advance the formal negotiations inside the UN process.

Of the short term finance pledged, many countries have it in their budgets and will channel it through the existing Kyoto Protocol measures and bodies. No more meetings are therefore required to implement it.

The next COP (16) is expected to be held in Mexico from 29 November 2010 to 10 December 2010. De Boer wants an "incentivised negotiating schedule" before then, in the second part of this year, details yet to be determined.

At the end of May / early June there will be a review of progress towards Mexico. Mexico could conclude in a legally binding agreement, but that can only be decided then. De Boer said he had spoken to 15-20 countries sine Copenhagen, who believe that discussions in Mexico will reach a conclusion after which it will be decided how to package it in legal terms.

The decision making process


The cumbersome nature of discussions came under much criticism at Copenhagen. Individual countries could hold up major discussions on points of order.

Could it be improved upon? De Boer now believes that "You can't have 192 countries involved in all the details all of the time on all issues.

"These are the most complicated negotiations the world has ever seen. They must be broken up into smaller parts. Transparency is vital. Countries will decide where they want to be involved.

"Then, when any decisions are brought back to the whole community, nothing is agreed until everything is agreed. This will build confidence among all parties," he said.

The vulnerable countries strike back

Many countries feel excluded from the UN process. Pablo Solon, Bolivia's ambassador to the UN said on 18 January:“The US climate envoy Pershing must be very deaf if he thinks that only a small minority of countries opposed the Copenhagen Accord. The agreement was roundly condemned in almost every quarter of the world, because it patently fails to tackle the climate crisis.

"The leaders of the world's largest polluting nations have failed us. That is why Bolivia is organizing a Peoples' Conference on Climate Change in April to put forward effective proposals for saving humanity from climate chaos. We invite all people committed to saving our planet to join us.”

Climate Justice will mean radical reduction of emissions in industrialized countries and the transfer of resources and technology to developing countries.

"If the US and other governments can so easily find money for endless wars, bank bailouts and bonanza bonuses for the rich, they clearly have the resources to help save lives and protect future generations.”

Solon added: “The US admission that it wants to exclude the vast majority of the planet from decisions about climate change is deeply offensive, when the climate crisis will fall first on those who are most vulnerable.

"The earthquake in Haiti has shown very clearly how vulnerable impoverished countries will be to environmental crises. The US decision to ignore our voices is the attitude of a colonial ruler.”

Europe struggles to lead the way


The Commission has proposed immediate action on climate finance agreed in Copenhagen, including fast-start funding ($30 billion) for 2010-2012 and long-term finance ($100 billion per year in 2020).

At an informal meeting of European energy and environment ministers in Seville on 16 January there were calls for swift implementation by the EU of the Copenhagen Accord. They urged other countries to follow suit and reach a legally-binding agreement in 2010.

"Doing so will require an active outreach by the EU, including at bilateral and regional levels, but possibly also through facilitating a meeting of 'Friends of the Accord' during the first quarter of 2010," a statement said.

The EU (which accounts for about 14% of the world's CO2 emissions) has committed to achieving a 20% reduction of greenhouse gas emissions by 2020 compared to 1990, as called for in its climate and energy package adopted in 2008. It would commit to 30% if other developed countries commit to comparable emission reductions and economically-advanced developing countries - namely China and India - contribute adequately according to their responsibilities and respective capabilities. 

The nominee for European climate commissioner, Connie Hedegaard, told a European Parliament hearing on 15 January that she hoped the EU's conditions for moving to 30% would be met before a meeting set for Mexico later this year.

The EU's newly-appointed president Herman Van Rompuy (a former Belgian prime minister) has said he will be focusing on Europe's recovery from the financial crisis and on tackling climate change during his two-and-a-half-year tenure. 

Though the Copenhagen climate talks lfailed to meet European expectations, they laid a good foundation for further work, Van Rompuy told the German chancellery. 

Angela Merkel has said that without European participation in the Copenhagen summit, China and India would not have taken any responsibility or confronted the issue of climate change. 

In March there is an EU Summit to endorse the European Energy Action Plan for 2010 onward.

US prospects


The loss of a Democrat majority in the US Senate on 20 January was seen as potentially making it more difficult for the US cap-and-trade climate change bill to be passed.

Steny Hoyer, Democrat leader in the House of Representatives, said the bill was not dead, but parts aimed at increasing energy independence were more likely to pass than those aimed at reducing carbon emissions.

De Boer put a brave face on the news: "No political development in US will mean we go back. US concerns on fuel prices and scarcity and economic problems will not go away.

"At Copenhagen Obama committed to a reduction of 17% - the global community will hold the US accountable to this," he said.

Have your say on new nuclear power stations

A consultation on new nuclear power stations is underway.

The potential sites for these are at Bradwell, Braystones, Hartlepool, Heysham, Hinkley Point, Kirksanton, Oldbury, Sellafield, Sizewell and Wylfa. Bradwell was nominated by EDF, who are currently seeking to sell the site to a credible nuclear operator.

Under new planning laws which make it harder for people to object, large infrastructure projects (like nuclear power stations, railways, large wind farms, power stations, reservoirs, harbours, airports and sewage treatment works) are subject to generic consultation periods conducted by the new Infrastructure Planning Commission, with individual instances having restricted subjects on which it's possible for locals to comment.

The Department of Energy and Climate Change's consultation on the Energy National Policy Statements ends on the 22nd February, followed by an opportunity for Parliament to comment.

Nuclear power is a step in the wrong direction, sucking capital and engineering know-how into a short-term technology with a terrible long-term legacy of nuclear waste.

Instead support energy efficiency to reduce the demand. Support renewable energy whose fuel is harmless and free and will never run out.

A map of potential sites for new nuclear is here.

Early praise for Sustainable Home Refurbishment

Sustainable Home Refurbishment: The Earthscan Expert Guide to Retrofitting Homes for Efficiency by David Thorpe
Sustainable Home Refurbishment: The Earthscan Expert Guide to Retrofitting Homes for Efficiency
, to be published by Earthscan in June 2010

Just in: some nice praise for this title:

"This is an excellent book - comprehensively-researched,
powerfully-presented and crystal clear. It should be the first stop for
anyone seeking objective advice in a field cluttered with misleading claims.
I couldn't recommend it more strongly." - George Monbiot

"As the idea of radical retrofit of our existing housing stock gradually moves from geek-dom to chic-dom, this book is a must have for all involved in this burgeoning industry. This book is both for the capable amateur and the professionally engaged.
"There is all the detail you could wish for with a vast array of practical examples and materials. This is not a book for the total novice but is a life saver for anyone on the road to radical retrofit.
"We can't recommend it highly enough. David has managed to make the book a good and interesting ready whilst managing to get all the necessary hard-core energy information in there as well." - Penney Poyzer (tv presenter, writer, "Queen of Green", grass roots activist) and Gil Schalom (architect).

Earth: Art of a Changing World at the Royal Academy

Yesterday I visited the Earth: Art of a Changing World exhibition at the Royal Academyd exhibition at the Royal Academy. It's fantastic, the best show I've been to in a long time - superior to the Radical Nature one at the Barbican earlier this year.

It collects works by many artists that have enviromental themes, especially addressing climate change. In many ways it does what the Centre for Alternative Technology's (CAT) Arts in Transition initiative wants artists to do.

It's not overwhelmingly polemical. Many of the works are oblique, some funny, many sad or touching, some make you angry, and a surprising number are very beautiful.

36 pieces are gathered under the following themes: Introduction; External, Perceived Reality; Destruction; the Artist as Explorer; and Re-Reality. Many current art world stars are represented, including David Nash, Anthony Gormley, Keith Tyson, Sophie Calle, and Tracey Emin - whose 3 pieces are the best things by her I've seen - touching and beautifully executed.

Several artists have been to Greenland on Cape Farewell tours, specifically organised to expose artists to the physical effects of climat change in the arctic. Novelist Ian McEwan, who went on one such trip, is represented by a text he wrote in response.

Yael Bartana's video about Israeli men driving their 4x4s over sand dunes for kicks is crazy - is this the summit of human progress? 'Progress' is also questioned by Lemn Sissay's poem, performed in a video with a jazz trio, "What if?" - poignant and challenging.

Another video, 'Doomed', by Tracey Moffat, is a hilarious compilation of disaster sequences from Hollywood movies. Yao Lu alters an image of rubbish dumps to make them seem at first glance like traditional Chinese landscapes.

Clare Twomey's ceramic flowers and Adriane Colburne's fabulous installation Up From Under the Edge of the Earth, are among pieces that by being incredibly beautiful and fragile remind us of the care we need to take to preserve our awesome natural environment, while Edward Burtynsky's photographs of Canadian tar sand exploitation, quarries and a Chinese chicken-processing factory (whose rows of women workers themselves look like factory farmed chicks), show us how little care some industries are taking.

Finally, we are made to hope that Antti Laitinen's documention of his long, futile attempt to make an island in the freezing Baltic Sea, striving like King Canute to fight the inevitable tidal forces, is not a prophetic allegory for humanity's attempt to stave off the effects of global warming.
