Why Wind Farms?
Fighting fossil fuels, and machines powered by them, has been my life’s work. As an energy analyst, I can tell you that the science on global warming is terrifyingly clear: To have even a shot at fending off climate catastrophe, the world must reduce carbon dioxide (CO2) emissions by at least 50 percent within the next few decades. If poor countries are to have any room to develop, the United States — the biggest emitter by far — needs to cut back by 75 percent. Although automobiles, with their appetite for petroleum, may seem like the main culprit, the No. 1 climate change agent in the United States is actually electricity. The most recent inventory of U.S. greenhouse gases found that power generation was responsible for a whopping 38 percent of CO2 emissions. Yet the electricity sector may also be the least complicated to make carbon free. Approximately three-fourths of U.S. electricity is generated by burning coal, oil or natural gas. Accordingly, switching that same portion of U.S.
