A report by the Department of Energy and Climate Change says the huge expansion is necessary if Britain is to meet greenhouse gas emissions targets.
Chris Huhne, the energy secretary wants to convert all Britain’s vehicles and homes to run on electricity by 2050, the Sunday Times reported. This will require a sharp increase in electricity generation by as much as double, with almost all coming from low-carbon sources such as wind and nuclear power.
There are currently 3,000 onshore turbines and several hundred offshore. They have helped cut carbon emissions but generate just 1-2pc of the nation's power.
The programme risks transforming Britain's wild landscapes, with an estimated 6,000 to 10,000 turbines needed onshore and up to 25,000 required offshore, with many visible from land.
Until there are dramatic increases in solar and wave power technology wind turbines and nuclear are regarded the most viable green energy sources.
