Biomass is a term referring to all organic matter that has stored energy through the process of photosynthesis, the process used by plants and other organisms to convert light energy from the sun into chemical energy that can be later released to fuel the organism’s activities and functions.
Since plants live and grow they are, by definition, a renewable resource. Biomass is one of the most plentiful sources of renewable energy in the world. In the past two decades it has been second only to the use of hydropower in the generation of electricity.
