This document discusses biomass energy. It defines biomass energy as using organic matter for fuel and lists various types including natural biomass from natural systems without human intervention, residual biomass from farming waste and byproducts, and produced biomass from crops cultivated specifically for fuel. The document also covers the theoretical bases of biomass energy, how it works by combusting biomass to produce heat and power turbines, its advantages of producing less carbon dioxide emissions than other energies but also its higher costs and lower efficiency compared to other fuels. Principal biomass-using countries in the EU are also listed.
