What are offshore windfarms?

How do they work?

The energy of the wind is captured in the rotation of the wind turbine's blades. The rotation of these blades generates power that the nacelle (the box containing the generator) converts into electricity. This is then transmitted via submarine cables to land where it feeds into the National Grid, which provides the electricity to power our homes.To see what an offshore wind farm looks like click here.

A standard 2 MW wind turbine provides enough power to supply 1367 homes. It is calculated that a 30x40km area of seabed could support enough wind turbines to supply 10% of the UK’s electricity.
