Survey 2009

Important note: We regret that due to lack of available effort, this website has not been updated for some time.

Much of the general explanatory text is, of course, still valid and hopefully useful. Detailed information on status, however, does need updating in many places and a number of recent developments are not covered. If you might be interested in helping, please contact the webmaster. Some examples:

Global warming: To limit global warming, net carbon emissions must go to zero – not just stop rising. From 2014 to 2016 they did at least stop rising, a small step towards what's needed. But in 2017 emissions rose by 1.6%, and it now looks like emissions in 2018 will be up by about 2.7% due to increased use of vehicles and coal. This is extremely worrying.

Green energy: Onshore wind is now very inexpensive and offshore wind (the only renewable technology still strongly supported by the UK government) has become cheap enough to be competitive. Solar is also very competitive even without subsidy, especially in sunny regions. In the UK, tidal power suffered a serious blow when the Swansea Bay lagoon project was turned down by the government.

Nuclear power: The NuGen reactors at Moorside have been cancelled by Toshiba as the company was virtually bankrupted by cost overruns in the US, but Hitachi's Horizon project for Wylfa is still active. EdF's EPR reactors in Finland and Normandy have still not started up but work is proceeding at Hinkley Point – the best guess for a completion date is 2027 (or later).

Cars: There are now some diesels that are relatively clean, but of course they still burn fossil fuels. Electric cars are steadily improving and there are some interesting new models. There is also a wider variety of plug-in hybrids available.

Lighting: LEDs have dropped in price and their performance has improved. For almost all applications they are the only sensible way to go. Look especially for ratings of A++ as these are significantly more efficient than CFLs (also known as low-energy bulbs) or fluorescent tubes.

Government grants: The feed-in tariff for new installations of solar photovoltaic panels will end in April 2019. There is, as yet, no proposed mechanism to pay solar panel owners for exporting electricity to the grid. Battery storage systems for domestic solar panels can help people to use more of the electricity they generate, but the cost of these is still quite high.

Smart meters: The rollout of smart meters has been much slower and more expensive than planned, and utility companies are still installing first-generation (SMETS1) meters that often don't work when energy supplier is changed.

The Initiative

The Blewbury Energy Initiative is a project of Sustainable Blewbury. We aim to reduce energy consumption and to encourage the use of renewable energy resources wherever possible. We hope to reduce the amount of coal, oil, gas and electricity used, and to help the global environment.

Financial support for insulation and domestic renewables, including the Feed-in Tariff and Renewable Heat Incentive



  • The government’s Green Deal was aimed to be its flagship policy for improving the energy efficiency of homes, in order to reduce carbon emissions and the use of fossil fuels. It has now terminated for new applicants. Although the Green Deal was widely agreed to be misconceived and take-up was very low, no scheme to replace it has been promised.
  • The government’s Renewable Heat Incentive for domestic properties is still running; it covers solar thermal hot water, biomass boilers and stoves, and air-source and ground-source heat pumps. See our domestic grants page for more information.
  • Beware of buying energy-related products from someone who phones, emails or texts you, or turns up on your doorstep uninvited. Frequent cold calls offer to install insulation supported by ‘government’ grants – when challenged no details are given. Beware of offers that claim to be ‘surveys’ and deny they are selling anything.
