How our electricity reaches your property
We don’t deliver renewable electricity to your property direct from a wind or solar farm. Electricity is delivered through the National Grid, a melting pot of different types of energy.
As a green energy company, what we do is make sure that for every unit of electricity our members use, we buy a renewable generation certificate (called a REGO) to match. REGO certificates help us verify the amount of renewable energy we supply to the industry regulator, Ofgem. For Bulb, it's simple: 100% of our electricity comes from renewable sources like solar, wind and hydro. You can see the breakdown on our Fuel mix page or find out more about how we buy electricity.
