Decc’s “2050 Pathways Analysis” envisages a future in which, within five years, we shall be embarking on a wholesale switch away from gas and other fossil fuels to electricity. Out will go all cooking and heating by gas, and using petrol or diesel to power our transport. Instead Decc hopes that, by the 2040s, we will have more than doubled our electricity supply, by building up to 40,000 offshore and up to 20,000 land-based wind turbines; having a new fleet of “zero carbon” nuclear reactors; and only allowing gas or coal-fired power stations if they are fitted with “carbon capture and storage” (CCS), to bury their CO2 in holes in the ground.
