…the promise of renewables has consistently been oversold by the political class. Solar and wind energy both suffer from major structural deficiencies. As Bryce observes, they are “incurably intermittent” and very difficult to store, and have low power density. Because of their low density, solar and wind “require huge swaths of land — which often becomes unusable for other purposes.” …Our current national energy debate is heavy on passion and hyperbole; it could use a sizable dose of historical perspective and empirical reality. In that sense, Smil and Bryce have done a valuable service. Their new books should be mandatory reading for U.S. policymakers.
