Green Energy Comparison
Ecotricity's green energy
Ecotricity supplies a 100% renewable electricity mix. The company generates a significant amount of its own power from its wind and solar sites, and buys the rest from other renewable generators, though it does use some REGO certificates. Its gas supply includes a small amount of green gas, with the rest fossil gas supported by investment in direct carbon removal projects in Britain. It focuses on building new renewable energy generation rather than just buying certificates to match its supply.[1]
EDF Energy's green energy
EDF Energy supplies an electricity mix that is largely nuclear, with some fossil fuels and renewables. Because of its nuclear generation, it is a major producer of zero-carbon electricity. All its home energy tariffs are backed by zero-carbon electricity as standard. It focuses on zero-carbon generation rather than 100% renewable power, as nuclear energy produces no carbon dioxide emissions when generated.

Hi, I'm Rob, and I run Energy-Review.co.uk. I initially started this project in 2018 when I was looking to switch energy suppliers and found there wasn't a website that provided simple, data-backed reviews on all the suppliers available. Since then, I have spent a lot of time (too much, some may say!) looking at all publicly available data about each supplier and writing reviews using this information. These reviews are updated as regularly as possible, and any data is backed up by a source where necessary. I have also started writing guides on various energy-related topics, which hopefully you will find useful. If you find any issues, please use our contact form to let us know.
