Biomass - waste plant or animal material - can be burned to produce heat and electricity. Biomass in the form of sewage is turned into dried pellets, which are burned with coal in a power station to produce heat. The heat then produces steam to power electricity generators. Biomass is a clean fuel and uses waste products, however it costs money to transport and is as expensive as coal. Biomass pellets and wood chips are also burned locally to produce heat for a swimming pool.
