What is green energy?

Everyone knows we need to increase the amount of green energy we use, but what makes energy green? The diagram below should help.

The way electricity is generated varies greatly. Some comes from green sources (hurray!) and some from brown (boo!). However, it all ends up going into the National Grid and after that, it’s similar to water in a reservoir, it all gets mixed together.

We take our energy from the National Grid, so we can’t guarantee what ends up in your home will be totally green. But if you’re on our 100% Green Energy Plan we can guarantee that for every unit you buy, we will buy one unit of renewable electricity. This is backed by Renewable Energy Guarantee of Origin (REGO) certificates, issued by Ofgem, so you can be sure that you’re doing your bit for the planet.
