During 2011, the world set another record for the most wind power installed during a year--41,600 megawatts. The world wind market measured in dollars rose 18% to $71.5 billion from $60.5 billion.
It was globally just a $4 billion per year global industry as recently as 2000 and has had a meteoric rise.
The 41,600 megawatts of 2011 new wind generation will produce approximately the equivalent of 22 nuclear reactors sized at 600 megawatts each, roughly the size of the Three Mile Island unit that continues to generate power. Putting it another way, the world installed enough wind power in 2011 to supply about 12 million US homes or 24 million European homes. All in just one year.
China led 2011 wind installation, installing 18,000 megawatts; Europe installed 10,000 megawatts; the US 7,000 megawatts; and India was fourth with 3,000 megawatts. China installed the most wind for the fourth year in a row.
World wind power was approximately 238,000 megawatts by the end of 2011.
