Worstall was startled to discover that relying on “renewables” to generate our electricity would, according to DECC, be significantly cheaper than relying on conventional power sources, such as nuclear and fossil fuels. As everyone knows, renewable sources such as wind farms are far more expensive than conventional ones, hence their need for massive subsidies. But the model had been designed on the assumption that, with wind power, Britain would require much less energy, because we would have become more “energy efficient”, by insulating our homes and so forth. Using conventional electricity, on the other hand, would be much more expensive because we would be less “energy efficient” and would therefore need more power. As Worstall put it, the model thus contrives to show that renewables, instead of being twice as expensive as conventional power, would mysteriously cost only half as much.
