Wind power has taken off. It is now present in over 75 countries, and as of 2011, 24 of these each generate over 1,000 MW. More than 23,000 new wind turbines have been deployed globally bringing the world-wide total to over 199,000. Late in 2012 there was great concern regarding the nonrenewal of the Production Tax Credit (PTC). By year's end, construction activity had slowed. But with the PTC renewal, the wind industry has picked up again. The outlook has improved so much that market forecasters predict worldwide growth over the next five years. The U.S. still has the world's second largest single-country capacity. There is also good growth in China and India, and there is more to look forward to as countries look for greater renewable energy capabilities.
