A guide to household wind systems is the latest addition to the British Wind Energy Association's website. The attraction for small scale wind and other renewables is on the increase in Britain and the government believes micro wind generation could help in the fight against climate change. The Department of Trade and Industry estimates that by 2050, up to 30-40% of UK electricity could be produced by small and micro generation technologies -- including 6% from small wind. Indeed, in his greenest Budget to date, Chancellor of the Exchequer Gordon Brown has allocated an additional £50 to micro generation technologies. Another enthusiast is Conservative opposition leader David Cameron who plans a rooftop wind turbine in addition to other renewable technologies at his West London home. Visitors to the BWEA website will now be able to find information on the range of technologies available, grants and planning issues, along with case studies of existing installations, from homes and businesses to schools and farms.
