Appalling Delusion
In 2016, shortly before his death, at age 46 from cancer, David J.C. MacKay, a physics professor at the University of Cambridge, said wind turbines are “a waste of money.” Eight years earlier, MacKay had published Sustainable Energy — Without the Hot Air, a remarkable book that hammered home the land-use impacts of renewables. (It’s available for free download.) MacKay, who recognized nuclear must be part of any effort to reduce carbon-dioxide emissions, calculated that wind energy needs about 700 times more land to produce the same amount of energy as a fracking site. In the same 2016 interview, MacKay called the idea of relying solely on renewables an “appalling delusion.” He continued, “There’s so much delusion and I think it’s so dangerous for humanity that people allow themselves to have these delusions that they’re willing to not think carefully about the numbers and the realities, and the laws of physics and the realities of engineering... humanity really does need to pay attention to arithmetic, and the laws of physics.”
