Green energy is produced from renewable sources and is intended to be environmentally friendly. It produces less carbon emissions than coal and oil.

If you choose a green energy tariff, you will be supplied the same energy from the National Grid as a household on a non-green tariff. However, your provider will match all or some of the energy you use with renewable energy that it will feed back into the National Grid, boosting the overall amount of green energy in supply.

Your supplier may also invest in green projects, such as the planting of trees, to reduce the amount of carbon in the atmosphere.

Green energy includes:

Solar Solar energy captured using panels which convert sunshine into usable energy. As with wind turbines, solar panels can be installed across huge expanses of land to create solar farms. They can also be fitted to individual properties’ roofs.

Wind Wind turbines are used to power generators that feed electricity into the National Grid. Wind farms are created from the installation of turbines across acres of rural land and off the coast.

Tidal Energy produced by the rise and fall of the tide is captured by a barrage positioned across the mouth of a river or a bay

Hydroelectric A dam or barrier is used to create a reservoir of water. The controlled flow of the water drives a turbine which creates electricity that can be stored, if necessary, until needed. It is one of the most reliable renewable energy sources as it is not dependent on the wind or sunshine.

Geothermal This technology captures natural heat from within the earth and uses it to generate power

Bioenergy Processes such as anaerobic digestion break down animal or food waste to produce green gas, while other organic matter can be burned to generate electricity.
