For a home wind turbine to be worth your investment, you really need to live on an acre or more, according to the U.S. Department of Energy. Living in a rural area helps, because if you’re in a residential neighborhood, you’re likely to run into conflicts with zoning and local homeowners associations.

How long does it take a wind turbine to pay for itself?

They conclude that in terms of cumulative energy payback, or the time to produce the amount of energy required of production and installation, a wind turbine with a working life of 20 years will offer a net benefit within five to eight months of being brought online.

How much does a wind turbine make in money?

Each of the landowners whose fields either host turbines or who are near enough to receive a “good neighbor” payment, can earn $3,000 to $7,000 yearly for the small area ” about the size of a two-car garage ” each turbine takes up.

Why do farmers not like wind turbines?

Although wind power plants have relatively little impact on the environment compared to conventional power plants, concern exists over the noise produced by the turbine blades and visual impacts to the landscape. Wind plants can impact local wildlife. Birds have been killed by flying into spinning turbine blades.
