biomass, landfill gas/biogas
Biogas is created through the breakdown of any organic material in an oxygen-poor environment. The resulting gas byproduct is mostly methane and carbon dioxide. Biogas is similar in composition to conventional natural gas and as such can be compressed or fed into a municipal gas grid. It can be used for many different purposes including cooking, heating, lighting, transportation, and electricity production.

It can be either tapped from the underground activity in a landfill site, or it can be produced in specially constructed anaerobic digester tanks. Farms with such tanks can process manure into biogas reducing the amount of nitrous dioxide and methane that would otherwise enter the atmosphere. These two gases have a far greater atmospheric warming effect than does carbon dioxide (nitrous dioxide = 310 times greater, and methane = 21 times greater).
