Thermoelectric plants, which use nuclear or fossil fuels to heat water into steam that turns a turbine, supply more than 90 percent of U.S. electricity and account for 40 percent of the U.S. freshwater usage; in Europe, these plants supply three-quarters of the electricity and account for about half of the freshwater use; warmer water and reduced river flows in the United States and Europe in recent years have led to reduced production, or temporary shutdown, of several thermoelectric power plants; a new study says this problem will only grow.

Warmer water and reduced river flows in the United States and Europe in recent years have led to reduced production, or temporary shutdown, of several thermoelectric power plants. For instance, the Browns Ferry Nuclear Plant in Alabama had to shut down more than once last summer because the Tennessee River’s water was too warm to use it for cooling.

If you grew up in the 1950’s and early 60’s, you probably remember the faint air of existential angst that lingered constantly in the background. With the creation of atomic weapons, and the booming stockpiles of missile-mounted bombs in the arsenals of the U.S. and the U.S.S.R., it seemed perfectly plausible that an all-out nuclear war could wipe out a significant fraction of the world’s population — the first time in history that humanity was capable of such destruction.

But as Fred Guterl says in a sobering, important and highly readable new book, those were really the good old days. The nuclear threat has receded, he acknowledges in The Fate of the Species: Why the human race may cause its own extinction and how we can stop it (Bloomsbury: $25), but warns that “the success of Homo sapiens has created new and terrifying risks that didn’t exist a few decades ago.”
