As the Earth is heated by the Sun, some regions become warmer than others. The air in the warm regions rises. Air from cooler regions rushes in to replace it. This creates air currents – what we know as wind.

Winds affect every part of the Earth. There are over 130 wind farms in the UK and many more are under construction.

Wind turbines can be put in any area where there is a lot of wind.

The wind blows turbine blades, which then turn. This turning motion is transferred to a generator to produce electricity.

Key Facts

• Wind power is a renewable source of energy, which means that it will not run out.
• As one of the windiest countries in Europe, it is perfect for our climate.
• The land between the turbines can be used for farming.
• Wind turbines can be used to supply energy in remote places.
• There is no need to dig underground or drill for the resource; therefore there is less pollution of the soil.
