One million homes in Britain are now using “green gas” for heating and cooking after a surge in energy produced from farm and food waste. Biomethane plants – there are now 60 in the UK – use food leftovers, cattle and chicken manure as well as grass silage and hybrid rye to create gas. According to the Green Gas Certification Scheme, the number of homes supplied with green gas has leapt 13-fold since 2017. Campaigners say it could supply as many as 10m UK homes by 2050. Should you be joining them? Most big suppliers now have green tariffs, although few are 100% renewable, and only one, Green Energy UK, guarantees that all its gas is green. Bulb, the most popular cheap green tariff, scores a five-star rating, but while 100% of its electricity is from renewable sources, just 10% of its gas is green. Green Energy UK promises 100% green gas and electricity, but on our test was the priciest tariff, although only a shade above the cost of the British Gas standard dual fuel price.
