According to a just-released study by Emerging Energy Research entitled US/Canada Wind Power Markets and Strategies 2005-2010, the record year for US wind power installations in 2005 is a direct result of the extension of the production tax credit (PTC), first at the end of 2004 and further extended to 2007 through the passage of the Energy Policy Act of 2005. This three-year horizon will break the boom and bust cycle that has plagued the US wind industry. And the passage of new state level portfolio standards, as well as amendments to existing standards, are also enhancing the long-term prospects of the US market.

The North American wind turbine market saw record growth in 2005; installations surpassed record levels seen in 2001 and 2003, with the majority of them onshore. From an industry that finally broke US$3 billion in 2005, the market is expected to more than double to just under US$7.5 billion in 2010. These figures, detailed in the EER study, factor significant price increases implemented for projects in 2006 and beyond, but also take into consideration greater vendor competition that will arise as local manufacturing capacity and new turbine models are introduced in the coming years. Improved competition will, however, not be sufficient to reduce prices to the extent they have risen for 2006.

North American wind power is expected to see a more than fourfold increase in wind power plants in operation by 2010. The US is expected to grow from just over 6,700 MW to over 28,000 MW by 2010. Starting from a lower base of nearly 450 MW in 2004, Canada's wind power base will grow even more quickly to over 6,200 MW by 2010.
