Biomethane, or biogas, is offered by some of our fellow green suppliers. Biogas is made from organic matter such as animal and food waste and can be added to the gas system (it currently accounts for around 4% in the UK). However, apart from being very expensive for customers, large scale production is not yet possible and we do not believe it is the best route longer term. We want to ditch gas for good. So, instead of investing in biogas, our approach is to invest in clean electricity initiatives to build a world where we do not need gas at all.
