How dirty is your power supplier?

Ecotricity, which figures prominently on green lists, mixes coal, nuclear, renewables and gas in almost equal amounts. The firm concedes it does not have a 100% green fuel mix although it does offer a 100% green supply for those who want it. "We are working towards more renewables. Our most popular tariff is made up of around 70% brown energy. Buying existing green energy, which is what most 100% tariffs contain, does nothing at all to reduce CO2 emissions or increase UK green energy capacity - you simply take something that already exists and have it for yourself.

"Robbing Peter to supply Paul is how we like to describe it. Most 100% green tariffs are a con, because they tell you you'll reduce your carbon footprint etc, but don't tell you someone else's will go up as a direct result. Nothing really changes - it's just a redistribution of existing green sources."
