Power in the Wind (W/m2)
= 1/2 x air density x swept rotor area x (wind speed)3

How you get electricity now: Electrical power from your utility flows from the electric grid into your home or business through a meter. The meter measures how much electricity you consume for billing purposes.
Wind turbines produce electricity: Electricity is produced from wind that turns the blades of a wind turbine creating kinetic (motion) energy. When the turbine blades capture wind energy they spin a shaft that goes from the hub of the rotor to a generator. The generator turns that rotational energy into electricity. The more intense the wind the more electricity is generated.
Converting power: The electricity that the wind turbine produces can either be directly used in your building, sent back to the utility for credit, or placed into storage batteries for later use. To accomplish this, the power coming off the turbine goes through a device called an inverter (a box the size of a small cabinet mounted near your electric panel.) The inverter monitors the wind turbine, conditions the power so it is identical to the utility's power, and keeps track of how much electricity is produced. The inverter output is fed directly into your building's circuit panel (a.k.a. fuse box) so it can feed merge with the utility's power and feed any circuit in the building. These circuits feed all the outlets in your house with a combination of wind and normal utility power in a seamless manner.
Using the wind power you have generated: As you need electricity, it is drawn first from the wind system. If you need more electricity than the system is generating, it is seamlessly supplemented with power from the utility connection. If you have a battery backup feature on your wind power system, it will kick in during a power outage.
Your meter turns backwards & saves you money: Electrical power from your utility flows from the electric grid into your home or business through a meter. The meter measures how much electricity you consume for billing purposes.
