After all the controversy of the wind power debate, I want to pass on a bit of optimistic news concerning solar power. According to today’s FT (you may need a subscription to read it), solar power costs have fallen dramatically and could compete on price with conventional power generation within three years. Admittedly, this is for the sunny south-east of the US and for commercial operations. Nonetheless, the rapid improvement of the efficiency of solar cells may mean that domestic solar generation of electricity might become viable within the next 5-10 years. It is unlikely that a typical UK house will be able to generate all its electricity needs alone and storage is an issue for night-time use, but it could greatly reduce domestic consumption. What happens to the wind turbines then? Even greater subsidies? Government policy may be backing the wrong horse. What chance in 20 years’ time that there will have to be a massive decommissioning of industrial wind turbines?
