Biofuel, any fuel that is derived from biomass—i.e,, plant or algae material or animal waste. Since such feedstock material can be recovered readily, biofuel is considered to be a source of renewable energy, unlike fossil fuels such as coal,natural gas and petroleum. Bioenergy is one of the many diverse resources that are available to help the meet of our demand for energy. It is a form of renewable energy that is derived from recently living organic materials known as biomass, which can be used to produce heat, products,transportation fuel, and electricity Biomass is renewable organic material that comes from plants and also from the animals. Plants produce biomass through a process called photosynthesis.Biomass contains stored energy from the sun. Biomass are often burned directly for warmth or converted to renewable liquid and gaseous fuels through various processes.
