England could produce 13 times more renewable energy
Onshore wind and solar could provide 226GWh of electricity without impairing food production, says Friends of the Earth
England could produce 13 times more renewable energy than it does now through onshore wind and solar, while using less than 3% of its land, analysis has found.
Onshore wind and solar projects could provide enough electricity to power all the households in England two and a half times over, the research by Exeter University, commissioned by Friends of the Earth (FoE), suggested.
Currently, about 17 gigawatt hours of electricity comes from homegrown renewables on land. But there is potential for 130 GWh to come from solar panels, and 96GWh from onshore wind.
These figures are reached by only taking into account the most suitable sites, excluding national parks, areas of outstanding natural beauty, higher grade agricultural land and heritage sites.
Some commentators have argued that solar farms will reduce the UK’s ability to grow its own food, but the new analysis suggests there is plenty of land that can be used without impairing agricultural production. More land is now taken up by golf courses than solar farms, and developers can be required to enhance biodiversity through simple measures such as maintaining hedgerows and ponds.
Onshore windfarms were in effect banned in 2015 by the then prime minister, David Cameron. Rishi Sunak last year claimed to make moves towards lifting the ban, through small changes to the planning regulations, but campaigners say they were ineffectual and real planning reform is needed. No plans were submitted for new windfarms in England last year, and few new developments are coming forward, despite high gas prices, rising bills and onshore wind being the cheapest form of electricity generation.
The calculations of the land needed exclude rooftop solar panels. Ministers have resisted calls for solar panels to be made mandatory on new-build housing. Kitting out a new-build home with renewables, high-grade insulation and other low-carbon features costs less than £5,000 for a housing developer, but retrofitting it to the same standard costs about £20,000, with the cost borne by the householder. Housing developers are among the largest donors to the Conservative party.
