How much electricity can a small wind turbine generate?
A small wind generator that you might put in a backyard might have a capacity of about one kilowatt. An average annual wind speed of nine mph would produce more than 200 kilowatt hours of electricity per year, and average wind speeds of 14 mph could produce more than 600 kilowatt hours per year.
Those towers cost as much or more, installed, as the turbine itself. How much tower you need for a wind turbine to live up to its potential depends on your particular site; on the trees and structures around it etc. Close to the ground the wind is turbulent, and makes a poor fuel for a small wind turbine.

The costs for a utility scale wind turbine range from about $1.3 million to $2.2 million per MW of nameplate capacity installed.
Are wind turbines expensive to maintain?
“The industry spends up to $8 billion on wind-farm maintenance.” To put this into perspective, the industry spends up to $8 billion on wind-farm maintenance, globally1, and is difficult to plug, especially when forecasts show that this figure is set to increase by 11% annually until 20252.
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.
Are birds killed by wind turbines?
Which source of mortality kills more or less birds is somewhat irrelevant ” birds are being killed by wind turbines and outdoor cats and window collisions, etc. And the threat posed by wind turbines grows with each facility constructed in a high-risk area for birds.
Are wind turbines loud?
Virtually everything with moving parts will make some sound, and wind turbines are no exception. However, well-designed wind turbines are generally quiet in operation, and compared to the noise of road traffic, trains, aircraft, and construction activities, to name but a few, the noise from wind turbines is very low.
How much does a wind turbine cost for a house?
Residential wind turbines vary depending on how much power they can produce and other factors. A rough range is $4,000 to $8,000 per rated kilowatt. A system that would offset most of an average home’s electricity use (10,000 kWh/year) will cost roughly $50,000 before incentives.
