You need to look closely at this chart to understand how dramatic it is, and what it can tell us. The left axis measures the “thermal efficiency” (or “heat rate”) of coal-fired plants (this is comparable to the gas mileage of your car), and CO2 emissions in grams per kilowatt-hour. You can see that the trendlines for the U.Ss. are basically flat, while China’s coal-fired power fleet has become much more efficient than the U.S. fleet over just the last half decade. What explains the difference? The U.S. isn’t building any new coal-fired power plants, because environmentalists have blocked them (last decade enviros celebrated blocking 10 new coal plants in Texas, for example); China is building new ones practically every week, and new ones are always better and more efficient than old ones. If we merely replaced our old coal plants with brand news ones, we’d lower CO2 emissions.
