Our energy mix


When you use energy, we want you to feel good about how it’s generated. All our energy plans include 100% green electricity, generated from renewable sources such as wind and solar. Many of our longer term plans also include greener gas. This is 100% carbon neutral gas, as we offset the carbon produced by investing in carbon reduction projects. With renewable electricity and greener gas, you’ll know you’re doing the right thing for the planet.
