The government's new energy adviser says the UK could face blackouts by 2016 because green energy is not coming on stream fast enough.
Professor David MacKay, who takes up his post at the Department of Energy on 1 October, blamed the public for opposing wind farms, nuclear power, and energy imports, whilst demanding an unchanged lifestyle.
He says not enough power capacity is being built and "the scale of building required is absolutely enormous".
Professor David MacKay: "The scale of building required is absolutely enormous. If we want to have a plan that mainly relies on renewables then we need to be imagining industrialising really large fractions of the countryside, or if we don't want to industrialise our countryside, other people's countryside. Places with lots of sunshine and places that can do a good job of growing energy crops more productively than us. If we don't want to industrialise the whole countryside then we have a very big building project to build the alternatives to our own renewables which are nuclear and so-called clean coal, which is as yet an unproven technology."
