Green Energy UK

Power sources: anaerobic digestion, solar, wind, biomass, hydro

Also known as GEUK, Green Energy (UK) Ltd are based in Hertfordshire and offer a nice selection of power sources to keep you going. Not only electricity, they also offer biogas produced through anaerobic digestion. The solids left over can be used as fertiliser, making their gas 100% green…maybe because it leaves the brown substances behind?

Octopus Energy

Power sources: solar, wind, hydrogen

Actually, Octopus Energy offset their customers’ use of gas, so not as good as Green Energy UK, but that’s still an immense undertaking. They also pay customers with solar panels for extra energy they generate and add that power to the greater network. An example of how many people contributing a small amount can make a big difference.


Power sources: solar, wind, hydro

With their green leaf on Ecosia’s search results, we know that Bulb are an organisation that has been assessed by ecological labels to ensure they really are sustainable. This is an extra level of validation the other companies don’t yet have, making Bulb the best choice. Leave the best till last, right?
