How many homes could be heated by cow poo?

Cow manure has the potential to heat millions of homes as a sustainable source of energy. Farmers like Richard Clothier in Somerset are converting cow waste into biomethane, already powering about 1 million homes but with potential for up to 15 million. Biogas plants like the one at Wyke Farms are producing energy from organic waste, offering environmental benefits and opportunities for rural economic growth. While harnessing biogas is considered a green energy solution, there are challenges in scaling production and concerns about its environmental impact compared to other renewable energy sources like electric power.
