1. It’s simple really- a wind turbine is a propeller attached to an alternator. When the wind blows over the blades of a wind turbine forcing them to turn, electricity is generated.

2. The electricity that is generated by domestic wind turbines is known as "wild AC" and is not suitable to power your household appliances or be fed into the national grid, so it is fed into an inverter which converts it first to DC and then into AC at the correct frequency to power your household appliances and be fed into the national grid.

3. This smoothed out electricity is then fed directly into you distribution board (commonly known as "the fusebox").

4. The inverter system automatically controls what happens: When the wind turbine is producing electricity at the same time it is required by the owner it is consumed on-site. When the wind turbine is producing more than is required onsite electricity is fed onto the grid. On still days when there is no wind, electricity is brought from the grid as normal.

5. In order to meter how much electricity is produced by the wind turbine we install a cumulative production meter (or ROC meter). This allows you to be paid for every unit of renewable electricity your turbine generate- even if you use it yourself, as well as any energy you export to the grid.
