The UK "should negotiate the abandonment, downgrading or its exit" from the EU Renewable Energy Directive, according to a report published today by right-leaning thinktank Policy Exchange.
Under the directive, the UK has to get 15% of its energy from renewables by 2020, up from 3% in 2009. But achieving this would have "hugely disproportionate costs", the report says.
Increased electricity prices caused by growth of renewables will also make it "harder to secure decarbonisation beyond the electricity sector, through electrification of transport and heating", it argues. Consumers will be unwilling to pay high fuel prices.
