Wind-Energy Use Growing in U.S., But Guidelines Lacking

Although use of wind energy to generate electricity is increasing rapidly, government guidance to help communities and developers plan wind-energy projects is lacking, says a new report from the National Research Council. The report, which assesses environmental benefits and drawbacks, estimates that by 2020, wind energy will offset about 4.5 percent of the CO2 that would otherwise be emitted by other electricity sources.
