Click on image for enlargement. The ultimate justification for alternative energy centers on its mitigation of global warming: Using wind, solar, and biomass sources of energy adds less greenhouse gas to the atmosphere. But because greenhouse gases have global effects, the efficacy of this substitution must be judged on a global scale. And then we have to face the fact that the Western world’s wind and solar contributions to the reduction of carbon-dioxide emissions are being utterly swamped by the increased burning of coal in China and India. The numbers are sobering. Between 2004 and 2009 the United States added about 28 GW of wind turbines. That’s the equiv...
