Wind Power installations to triple between 2007 and 2012 accroding to a brief history of wind power as reported in The Economist.

Globally, wind power installations are expected to triple from 94GW at the end of 2007 to nearly 290GW in 2012, according to BTM Consult, a Danish market-research firm. They will then account for 2.7% of world electricity generation, the company predicts, and by 2017 their share could be nearly 6%.

Well behind much of Europe in percentage of electricity generated from the wind, the US has 18% of worldwide wind power production following a year which saw an increase of 45% in wind power capacity.
