For more than two decades, governments have been assisting utilities, power developers, local communities and other related actors to remove technical and economic obstacles to wind power investment, in the hope that wind energy would become the basis for community revitalisation and, ultimately, a commercial reality independent of government subsidies. A plethora of articles have documented the impact of market and state efforts to improve the technology, cost-effectiveness, reliability and effi cient use of renewable energy for public use. In particular, recent studies have examined the rising productivity of turbines, to the present power output of about 3 MW each, and forthcoming higher output prototypes.
