A renewable energy company is supplying the people of Bristol with a unique and potentially endless source of clean energy -- gas made from rotting sewage.
Geneco is supplying local energy firm Bristol Energy with the fuel, which is generated by fermenting sewage via anaerobic digestion in massive tanks to create a biomethane of similar composition to natural gas. This is then sold into the grid and used to supply homes in the area, which sounds like an entirely sensible and sustainable option, seeing as people seem to enjoy pooing almost as much as they love turning on the central heating.
The company thinks it treats enough sewage each year to power 8,300 homes in the area, with Bristol Energy's green tariffs promising to incorporate some local flavour into the the gas supplies of its customers. [BBC]
