Wind power could supply up to 12 percent of global electricity by 2020 and more than 20 percent by 2030, a new study by the Global Wind Energy Council (GWEC) and Greenpeace shows.

Wind energy installations totaled 240 gigawatts globally by the end of 2011, and the industry is set to grow by at least another 40 GW this year, the study says. By 2020, under the scenario put forth by the International Energy Agency, total capacity would reach 587 GW, supplying about 6 percent of global electricity.
