Last week, the head of Germany’s national grid warned that supply was in such a parlous state that major power cuts may soon be inevitable. Like Britain’s, Germany’s energy policy has been so skewed by green obsessions that it has built 22,000 wind turbines, more than any other country in the world. Yet they are even more useless than ours – generating at only 15 per cent of their “capacity” (ours managed 21 per cent last year). Even the 6 per cent of the nation’s electricity they supply is so unreliable that the Germans say they must not only keep open several coal-fired power stations – in defiance of an EU anti-pollution directive which is shortly to close six of ours – but that they must build new ones, to burn some of the world’s “dirtiest” coal.
