‘Green electricity’' means electricity produced from sources which do not cause these impacts upon the environment. Of course, every type of electricity generation will have some impact, but some sources are much greener than others. The cleanest energy sources are those which utilise the natural energy flows of the Earth. These are usually known as renewable energy sources, because they will never run out.

Wind power

The winds that blow across the UK can be harnessed by turbines to provide electricity. Wind turbines sited in suitable locations already provide a small, but growing percentage of the UK's electricity, and are used successfully all around the world. In fact wind power is one of the world’s fastest growing energy sources! Wind turbine technology has greatly improved over the last ten years, making wind turbines quieter and more efficient so that electricity generated from the wind is now often competitive with traditional coal-fired and nuclear power stations. Wind turbines are also beginning to be built at sea — in the future much of our electricity could come from these offshore windfarms.
