How do clean tariffs work?

Most UK homes are powered by electricity from the National Grid, and their electricity may be produced by any number of regional generators, using both ‘dirty’ and clean sources. If you’re wondering how your tariff could be ‘clean’, imagine the Grid being a bit like a pond, with both dirty water and clean water flowing into it. When you sign up to a clean tariff, the supplier guarantees that they’ll put as much clean energy into the pond as the energy you take out. The more people who buy clean electricity, the more clean energy is guaranteed to go into the pond, and the cleaner the pond gets.
