Power plants choose that most renewable of fuels.
Power from pig poop. Sounds like a skit from Saturday Night, but it's not. In July, a bona fide dung-fired power plant came online in that most proper of nations, Great Britain. And according to the firm behind the project, Farmatic UK, the plant could be the first of many in Britain.
Dung-fired power plants are also popular in Germany and Denmark, which each has about 20 large-scale plants operating.
