LOOK TO THE FISHES

摘要

In The Electricity-Generating Game, energy efficiency can be the difference between profit and poverty, competitiveness and collapse. The most finely tuned wind turbines convert 47 percent of the wind that strikes them into electric energy. They compare favorably to the average coal-fired power plant, which is only 32.5 percent efficient, according to the U.S. Department of Energy. New combined-cycle natural gas plants can go as high as 60 percent, but most US. gas generators use older technology that averages 44.8 percent.
