Coal and nuclear are dying, and the future of energy lies in solar. This isn’t a Guardian reader’s fantasy, this is the established trend in energy markets. This isn’t a declaration of victory over carbon dioxide either – the trend isn’t fast enough to stop catastrophic climate change, at least not yet – but it’s useful information for policy makers. Unless you’re George Osborne, in which case it’s time to plough the nation’s remaining finances into life support for nuclear and coal whilst standing athwart history yelling ‘STOP!’
