Prof Susan Roaf: On 29 June the Department of Energy and Climate Change told me, on behalf of Amber Rudd, that “as you may know the government’s position remains that we are committed to seeing solar PV, including wide-scale deployment across community homes and rooftops”. On 7 July 2015 I held a party at the Oxford Ecohouse, with its 1995 first solar roof in Britain, to celebrate one million solar homes built in Britain in 20 years. DECC is now proposing to cut the feed-in tariff rates for solar PV installations by as much as 87%. Big Energy and DECC have realised that if everyone generates their own electricity and heats their water with solar systems, there will be no markets for nuclear electricity and fracked gas. No wonder they are determined to kill off the solar industry. Solar power is citizen power, so – if you do not want a toxic nuclear future or degraded fracked landscapes and lives – keep building those solar roofs, because each single one is a footstep to a cleaner, safer, freer energy future.
