"We will triple the amount of electricity we get from renewables by 2015. We want to lead in the development of carbon capture and storage. And we will consult on the significant role that new nuclear power stations could play in cutting emissions and diversifying our supply."
He also said that the UK was becoming increasingly reliant on imported oil and gas at a time when global demand is "accelerating".
"We will ensure that we make the most of our substantial remaining reserves in the North Sea, have a diverse range of sources for our imports and make further progress opening up markets in Europe and more widely," he said.
