Below is a photo of a Vestas Wind Systems' wind turbine.  With a 28 per cent market share, and more than 38,000 wind turbines installed, Vestas Wind Systems, a Danish company, is the world's leading manufacturer, seller, installer, and servicer of wind turbines.  

Vestas started making wind turbines in 1979, right as Europe began to dominate wind power generation, as they did for much of the 80's and 90's.  Now, with onshore wind turbine installation in Europe tapering off, major companies, including Denmark's Vestas's, Spain's Gamesa and Germany's Siemens see the United States as the "key to the industry's future" thanks to President Obama's promise of big investments in green energy, Which is why Vestas is, according to The New York Times, "rapidly expanding its production base in the United States, where it says it has created more than 1,200 skilled jobs..., and expects that number to climb to more than 4,000 by the end of 2010, if President Obama's Recovery and Reinvestment Plan is carried out." 

Of course this is not without doubt, as pointed out by Johanna Peace at WattHead:
The American Recovery and Reinvestment Act (ARRA) this year created a market boom by delivering $65 billion for clean energy, efficiency retrofits and similar investments, including $2.3 billion in tax credits for clean energy manufacturers and a three-year extension of the production tax credit for wind power.

However, the clean energy investments begun in ARRA are temporary. Clean energy manufacturing incentives are short-term and even the production tax credit, finally extended for more than one year at a time, will expire in 2012. If the US doesn't build on ARRA's clean energy down payment with a substantial, sustained policy of government support for the wind industry and other emerging clean technologies, demand for renewable energy is likely to collapse--and foreign firms like Vestas will quickly stop opening doors within US borders.
