Wed, 17 Dec 2025 How many homes could be heated by cow poo?

Some dairy farmers say Dairy cow manure is "nature's crude oil".

* A dairy farmer in Somerset turns his cattle waste into biomethane, describing it as "nature's crude oil".
* The process involves collecting manure, pumping it into an anaerobic digester where bacteria break down the organic material and release methane.
* Only 2.5% of Britain's annual 90 million tonnes of slurry is fed into AD plants, with a campaign underway to increase this number.
* Biomethane can replace up to 18% of total UK gas consumption, but energy analysts warn that potential may be overstated.
* Green campaigners worry that biogas will not be as green as it claims if the rest of the gas in the pipelines continues to come from fossil fuels instead of renewable electric power.
