A combination of new technology, financial incentives and growing environmental awareness have lead to an increasing number of wind turbine installations in residential areas, according to this article in the New York Times. With advances in wind power technology, the cost of each project is steadily coming down, making wind power a more feasible option for homeowners. Other homeowners are more driven to reduce global warming and dependence on fossil fuels. A number of state incentive programs is also increasing interest in residential wind power. Despite these advances, wind power remains costly. It can take 20 years to repay the cost of installation. But for a growing number of homeowners, it's a investment they are willing to make.
