This is a response to James Conca's article in Forbes on June 26, "Debunking the Unscientific Fantasy of 100% Renewables."
Conca's article describes a paper published in the Proceedings of the National Academy of Sciences (PNAS) by Chris Clack and coauthors on June 19, criticizing a paper colleagues and I authored in the same journal in 2015. Our original paper showed that the U.S. can transition to 100% clean, renewable energy in all energy sectors without coal, nuclear power or biofuels. In this response, I show that Conca was negligent by not reporting on our response in PNAS and by seriously misrepresenting facts.
PNAS published a paper today by nuclear and fossil fuel supporters, which is replete with false information for the sole purpose of criticizing a 2015 paper colleagues and I published in the same journal on the potential for the U.S. grid to stay stable at low cost with 100 percent renewable wind, water and solar power. The journal also published our response to the paper.
