How much wind is needed to power a home turbine?
Depending on the average wind speed in the area, a wind turbine rated in the range of 5–15 kilowatts would be required to make a significant contribution to this demand. A 1.5-kilowatt wind turbine will meet the needs of a home requiring 300 kilowatt-hours per month in a location with a 14 mile-per-hour (6.26 meters-per-second) annual average ...
How much does a household wind turbine cost?
The cost of a domestic wind turbine depends on what type you go for, how big it is, and who installs it. The average cost of a small roof-mounted turbine (between 0.5 kW to 2.5 kW), is about £2,000 5. But these don’t generate very much electricity, so it will take a very long time to recoup that cost.

How does a wind turbine meter work?
When your wind turbine system produces more electricity than you can use, that power is diverted to the public utility grid, and your meter spins backwards, as you are credited , at retail rates, for that power. As of December 2007, net metering is available in over 42 states and the District of Columbia.
What are the parts of a wind turbine?
The turbine is the spinning part of the wind turbine system that generates the electricity. The turbine consists of: 1 Blades – Most wind turbines have three blades, usually made of a plastic fiberglass composite. 2 Rotor – The blades are connected to a double rotor assembly. The blade rotor spins when the blades catch the wind. The magnet rotor spins around a magnetic alternator, creating a magnetic field and producing an electrical charge. 3 Controller – The controller converts the raw electricity to direct current (DC) power and sends it either to a battery or an inverter.
