Our fuel mix

At Good Energy, we believe the UK can be powered purely by renewables.

We source all our electricity from renewable sources like solar power, wind power, hydroelectric power and biogeneration.

We always have done and we always will.

What does “fuel mix” mean?

A supplier’s fuel mix shows the sources of the electricity that it supplies to its customers e.g. coal, gas, nuclear and renewables.

Over the course of a year, energy suppliers must buy enough electricity to feed into the national electricity grid to cover the amount their customers take out. At the end of each year, suppliers must disclose their fuel mix to the electricity and gas regulator, Ofgem. This information is published annually to help consumers make informed choices about their electricity supplier. At Good Energy, we make sure that all the electricity we sell to customers each year is matched 100% with electricity sourced from renewables. 

How do we know it's 100% renewable? 

At Good Energy, we generate renewable power from our own wind and solar farms and buy renewable power from small independent renewable generators. Added together, this will match the amount of electricity we supply to our domestic and business customers across the UK.

Our wind and solar farms

We own and operate six solar farms and two wind farms. Together these sites generate enough electricity to power over 18,000 homes.

Independent generators

The remainder of the power we buy directly from our community of over 1,600 independent generators across the UK. From local farmers and community energy schemes to sustainable businesses that generate their own power and sell us the excess. 

Other sources of renewable electricity

Renewable power from offshore wind farms has also become part of our fuel mix. We source electricity for our customers from Westermost Rough Wind Farm, situated in the North Sea, five miles off the Yorkshire Coast north of Hull. We purchase 12% of the overall output from the 210 MW wind farm. Over the course of a year, that’s enough renewable electricity to supply more than 33,000 average homes. 

Carbon neutral gas

We see natural gas as being a necessary transitional fuel, playing an important role in heating and cooking as we move towards the ultimate goal of a 100% renewable future. We are doing all we can to make this transition a reality, and in the meantime, are committed to offering a greener way to supply gas. 10% of our carbon neutral gas is biogas, which is produced from organic matter – like manure and sewage – right here in the UK. Biogas is chemically identical to natural gas but can be created and used with less impact on the environment.

To make it carbon neutral, emissions from the gas our customers use are neutralised through verified carbon-reduction schemes in Vietnam, Nepal and Malawi. Not only do these offset the carbon emissions from the gas we supply, they also bring many economic, social and health benefits to the local communities involved.
