Solar power could provide up to 4% of the UK’s electricity by the end of the decade, the government has said. The plummeting cost of solar panels has caused the government to revise upwards its forecast for solar energy use, Energy Secretary Ed Davey said. Speaking to the BBC, he said he had been “amazed and delighted” by the plummeting costs of solar power. Mr Davey said “This is wonderful for humanity. There are 300 million Indians without electricity… the effects in sub-Saharan Africa will be dramatic. Solar power will do to energy what mobile phones did for communication and markets.”
Ed Davey expects that up to 14GW of solar by 2020 – up from 5GW at the end of 2014. That equates roughly to 1.5% of total UK annual electricity to just under 4%. He said he expected it to grow further in the next decade. A government spokesman said there were now 650,000 solar installations in the UK.
