As the name suggests, Green Energy UK sources all of its electricity and gas from green and renewable sources. 

Electricity comes from hydropower, solar panels, wind and biomass. It buys directly from generators in the UK. Its gas is 100% ‘green’ gas from anaerobic digestion (where micro-organisms break down organic matter without oxygen to produce methane and biogas). 

It says it aims to make renewable energy mainstream and to offer competitive prices.  

Established in 2001, it's among the oldest energy firms outside the traditional biggest six and was the first energy supplier to launch a tariff using a smart meter to charge customers different electricity rates depending on the time of day. Called TIDE, it costs less for electricity used overnight and four times more at peak times. 

None of Green Energy UK's tariffs have exit fees.

It's not as cheap as I initially thought
