A home, or residential wind turbine, which is installed on top of a tall tower, operates by collecting kinetic energy from the wind and converting it to electricity. Electricity that is usable and compatible with a home’s electrical system.
In a typical home wind turbine setup, your house is powered by both the wind turbine and a local utility. If the wind speeds are below cut-in speed (7-10 mph) there will be no output from the turbine and all of the needed power is purchased from the utility.
As wind speeds increase, turbine output increases and the amount of power purchased from the utility is proportionately decreased. When the turbine produces more power than the house needs, the extra electricity is sold to the utility.
The wind turbine typically lowers your electricity bill by 50% to 90%. It is normal for wind turbine owners with total-electric homes to have monthly utility bills from $8 to $15 for 75% of the year.
