Good Energy’s tariff is a Green Energy Supply certified tariff:

Good Energy is the UK’s only dedicated 100% renewable energy supplier; all the electricity it supplies comes from renewable sources like wind, solar, hydro and sustainable biomass. This guarantee is backed up by their fuel mix disclosure and an annual independent audit, published in their annual environment report.

Good Energy’s electricity comes from a network of over 1000 independent generators throughout the UK, making electricity at home and in their communities as well as on a larger scale, and is committed to increasing the amount of renewable generation in the UK. It also owns its own wind farm in Delabole, Cornwall, which it is currently investing in repowering to more than double its output.

Good Energy is recognised as the leading supporter of small and medium-sized renewable generators. It believes that decentralised generation, where energy is generated at home and in the community, is better for our future energy security, as assets remain owned by the community rather than in the hands of a few big companies.
