I was recommended this book while being slaughtered in an argument about climate change and renewable energy. I was expounding the ‘green new deal’ idea, where the state could invest in wind power and other renewables while the recession is on and unemployment high. My opponent responded that wind power was not sufficient to meet our needs. Now, I’d heard it said that meeting our energy requirements with wind power would require covering most of the British Isles in wind generators, but this nay-saying had been shoved into the back of my mind. However, I had no figures to defend my position with, so the discussion moved on to other things.
