Once again we are confronted with Einstein’s dictum that mass = energy. In this case the mass is animal, food and agricultural waste and the converted energy is heat and electricity.
Cow manure is powering businesses in Canada’s province of British Columbia. The Vancouver Sun writes about a dairy in the city of Abbotsford is producing 170,000 kilowatts of electricity per year from 1.6 million litres of manure and is supplying surplus electricity to the province’s power grid. That electricity is then resold at a 40% premium by the non-profit renewable energy supplier Cowpower to businesses and organizations that want to reduce their environmental impact.
