Let’s take a look at the renewable energy suppliers that only offer a green energy tariff such as green electricity: Good Energy – Supplies 100% renewable electricity. For every unit of green electricity used by a consumer Good Energy promises to supply the national grid with a unit of electricity from renewable power sources.

Green Energy 100 – For every unit of electricity the consumer buys, Green Energy 100 buys one unit of renewable electricity. Green Energy 100 also invests 50% of profits into green electricity generation.

Ecotricity – For every unity of electricity the consumer buys, it supplies 0.1 units of green electricity – increasing by 10%/year – but also invests in wind farms.

In addition, npower offers the Juice ‘clean and green’ service which supplies one unit of renewable electricity for every unit of electricity you buy.

Scottish Power also has a ‘Green Energy Fund’, which invests up to £15.75/year/customer in green energy schemes, which is matched by the company.

Powergen offers GreenPlan in which they guarantee to match every unit of electricity supplied to GreenPlan customers with one from a renewable source and London Energy pledges to match the electricity you use with green electricity from renewable sources with their Green Tariff.
