The UK will struggle to "keep the lights on" if green energy policies are not changed, according to the former environment secretary.
Conservative MP Owen Paterson, who was sacked by David Cameron in the summer reshuffle, will say in a speech next week that increasing the reliance on renewable energy sources such as wind farms while cutting carbon emissions is a "flawed" plan, according to the Sunday Telegraph.
He will also call for the 2007 Climate Change Act, which requires Britain to reduce fossil fuels use, to be suspended until other countries sign up to similar restrictions and he wants a series of small nuclear power stations created to meet domestic power demands.
"Blind adhesion to the 2050 targets will not reduce emissions and will fail to keep the lights on," he will say. "The current energy policy is a slave to flawed climate action. It will cost £1,100bn, fail to meet the very emissions targets it is designed to meet, and will not provide the UK's energy requirements.
"In the short- and medium-term, costs to consumers will rise dramatically, but there can only be one ultimate consequence of this policy: the lights will go out at some time in the future.
“Not because of a temporary shortfall, but because of structural failures, from which we will find it extremely difficult and expensive to recover."
Caroline Flint, shadow energy and climate change secretary, said: "Owen Paterson's latest outburst points to the growing climate change denial in the Tory party. The fact that David Cameron appointed him as Environment Secretary for two years makes a total mockery of the Prime Minister's promise to lead the greenest government ever.
"Labour is proud of Britain's leadership on tackling climate change. Climate change is a threat to our national security and to scrap the Climate Change Act now would damage Britain's influence abroad and put a halt to much-needed investment in clean energy here in Britain."
