I worked in Denmark in Renewable Energy for couple of years and has First hand knowledge of Wind Energy growth there.

Year wise wind energy growth and percentage of Wind in the power in Denmark:
Year 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 Installed wind capacity (MW)

2,390 2,497 2,890 3,116 3,123 3,127 3,135 3,124 3,163 3,482 Electricity generated (TW•h)

4.22 4.31 4.86 5.56 6.58 6.61 6.11 7.14 6.98 6.72 Wind power share in the electricity supply (%)

12.1 12.2 13.9 15.8 18.5 18.5 16.8 19.7 19.1 19.3

Year 2010 2011 2012

Installed wind capacity (MW)
3,752 3,927 [4,004]

Electricity generated (TWh)
7.81 9.84 Wind power share in the electricity supply (%) 21.9 28.2

Wind turbine cooperatives in Denmark:

To encourage investment in wind power, families were offered a tax exemption for generating their own electricity within their own or an adjoining commune. While this could involve purchasing a turbine outright, more often families purchased shares in wind turbine cooperatives which in turn invested in community wind turbines. By 1996 there were around 2,100 such cooperatives in the country. Opinion polls show that this direct involvement has helped the popularity of wind turbines, with some 86% of Danes supporting wind energy when compared with existing fuel sources.
The role of wind turbine cooperatives is not limited to single turbines. The Middelgrunden offshore wind farm – with 20 turbines the world’s largest offshore farm at the time it was built in 2000 – is 50% owned by the 10,000 investors in the Middelgrunden Wind Turbine Cooperative, and 50% by the municipal utility company.
By 2001 over 100,000 families belonged to wind turbine cooperatives, which had installed 86% of all the wind turbines in Denmark. By 2004 over 150,000 were either members or owned turbines, and about 5,500 turbines had been installed, although with greater private sector involvement the proportion owned by cooperatives had fallen to 75%. The cooperative model has also spread to Germany and the Netherlands.

In fact I have been advocating the WIND FARM CO-OPERATIVES in India as hitherto Depreciation benefits are extended to big Industrialists and Companies. A Wind Fund can be created in India where Individuals paying Income Tax can be exempted for the investment under Section 80C.
