Windpower Engineering & Development
Wind power set a record breaking 22% increase in annual installations for 2015. There are at least 281,924 wind turbines generating 432,883 MW of power around the globe. In the United States alone, about 48,500 turbines generate 74,471 MW, enough to power about 20 million American homes, according to the Global Wind Energy Council. In addition, Bloomberg projects that 19 more GW of wind will be installed globally by 2021.
Governments around the world have seen the benefit of renewable energy and offer incentives to spur more installations. U.S. Congress recently passed a five-year, long-term extension with a phase out of the Production Tax Credit. The PTC lets owners of qualified renewable energy facilities receive tax credits for each kilowatt-hour of electricity generated by the facility over a 10-year period.
