An excellent book which puts our energy consumption in understandable kilowatt-hours per person per day terms and then quantifies, in the same terms, the energy we can get from different sustainable energy sources.This clarifies the size of the changes required in world energy supply. They are mindbogglingly huge.The question is not: `Wind or nuclear?' It is `What do we do given wind plus nuclear plus all other renewables plus CCS will not our demands?'The answer (which the book only hints at) is both lifestyle change and limits on the global human population. The sooner we realise this and act accordingly the less painfull the transition will be.
