Wind power in Canada
From Wikipedia, the free encyclopedia
Wind power in Canada amounts to an installed capacity of 2000 MW,[1] with at least another 700 MW of capacity expected to come online by the end of 2008. Wind energy currently accounts for 0.8% of Canada's domestic electricity supply, or roughly 540,000 households.

[edit] Overview
Early development of wind energy in Canada was located primarily in Ontario, Quebec, and Alberta. Throughout the late 1990s and early years of the 21st Century, every Canadian province has pursued wind energy to supplement their provincial energy grids. As of August 2007, British Columbia is the only province without an operating commercial wind farm, but BC Hydro (the province's electricity supplier) has currently issued Electricity Purchase Agreements for over 300 MW of wind-powered electricity.
| Year | Installed Wind Capacity (MW) |
|---|---|
| 2000 | 137 |
| 2001 | 198 |
| 2002 | 236 |
| 2003 | 322 |
| 2004 | 444 |
| 2005 | 684 |
| 2006 | 1460 |
| 2007 | 1770 |
With increasing population growth, wind energy in Canada has been seen as a way to diversify energy supplies away from traditional reliances on fossil-fuel burning thermal plants, and heavy reliance on hydroelectricity in some provinces. In provinces like Nova Scotia, where only 12% of electricity comes from renewable sources,[2] the development of wind energy projects will provide a measure of electricity security that some jurisdictions are lacking. In the case of British Columbia, wind energy will help close the electricity deficit that the province is facing into the 2010s and help reduce the reliance on importing power from other jurisdictions that may not use renewable energy sources.
| Province | Installed Wind Capacity (MW) |
|---|---|
| Alberta | 523 |
| Ontario | 501 |
| Quebec | 236 |
| Saskatchewan | 171 |
| Manitoba | 103 |
| New Brunswick | 59 |
| Nova Scotia | 72 |
| Yukon Territory | 0.81 |
| Newfoundland | 0.39 |
An additional 2,004 megawatts of wind power is to come on stream in Quebec between 2011 and 2015. The new energy will cost 10.5 cents per kilowatt-hour, a price the utility described as "highly competitive".[3]
[edit] Wind Hybrid Projects
Of potential use in smaller isolated communities not connected to the main power grid are Wind-Diesel and Wind-Hydrogen. One Canadian example is the community of Ramea, Newfoundland and Labrador[4] that initially used a Wind-Diesel system and is now being converted to Wind-Hydrogen technology.
[edit] Wind tower manufacture
Canadian industry has started to supply major components for Wind Tower projects; Hitachi Canadian Industries being one example.
[edit] Public opinion
In a survey conducted by Angus Reid Strategies in October 2007, 89 per cent of respondents said that using renewable energy sources like wind or solar power was positive for Canada, because these sources were better for the environment. Only 4 per cent considered using renewable sources as negative since they can be unreliable and expensive.[5]
According to a Saint Consulting survey in April 2007, wind power was the alternative energy source most likely to gain public support for future development in Canada, with only 16% opposed to this type of energy. By contrast, 3 out of 4 Canadians opposed nuclear power developments.[6]
