Wind power is gaining ground in Massachusetts, particularly along the Atlantic coast where high-speed winds are common. A number of wind projects are under consideration in the state, including a plan to build at least 10 turbines atop a mountain in western Massachusetts, which would be the state’s first commercial wind-energy facility. Wind power will likely be helped along by a state fund, created when Massachusetts deregulated its energy industry, is expected to spend $150 million on nonpolluting energy projects by 2003. As deregulation lets citizens choose their electricity provider, more people are expected to buy wind and solar power, even if it costs more than conventional energy.
