Letter Alan J Sangster: It is not just the power required by the electricity industry which needs to be converted to renewable sources. This is the easy bit. Climate change demands that all of our power consumption requirements, including heating and transport, must be fossil fuel-free. Currently Scotland’s energy needs add up to 142TWh, 22 per cent of which is directed toward electricity supply. The electricity supply industry will need to be four times larger to power our society once fossil fuels are abandoned. We have clearly a considerable way to go in converting to renewables, not just here but around the world. It should perhaps be emphasised that the intermittency problem, which is tediously recited by critics of renewable power, is well on its way to a solution through increasingly successful developments in large scale battery storage and in low level or coastal hydroelectric storage.
