Indeed, José Manuel Entrecanales, chairman of Acciona, the giant Spanish renewables company, told me that he used to be sprinting alone in the race to install renewables “with the wind in my face.” But now he finds the wind is at his back, and some of the biggest oil companies are trying to muscle into the race. That is not an accident, he said, considering that recent deals from Morocco to South Africa to Chile were struck for around 2.8 cents a kilowatt-hour of wind and 4.2 cents a kW-h for solar, making them highly competitive with fossil fuel.
