A renewable form and sustainable form of energy that is used for the generation of electricity or other forms of power is called as Biomass. Sun is the main source for Biomass. Through the process of photosynthesis, plant absorbs the suns energy. When this biomass is burned , due to the chemical energy certain heat is released. It can be directly converted to liquids biofuels or biogas or even burned directly. Burning is the only process for releasing energy in biomass. This renewable form of energy can be converted to other useable forms such as methane gas or for transportation purposes like ethanol and Biodiesel. Around  5% of the  prime usage of energy is served by Biomass. Wood, Wood waste, Straw, Manure, Sugarcane and many other agricultural goods are the prime source for the Biomass. Municipal solid waste also comprises of the biomass. Biomass in the form of dead plants, trees, grass, leaves, crops, manure, garbage’s, animals waste can be a great source of alternative fuels that can be used to replace fossil fuels. Burning either fossil fuels or biomass releases carbon dioxide (CO2), a greenhouse gas. However, the plants that are the source of biomass capture a nearly equivalent amount of CO2 through photosynthesis while they are growing, which can make biomass a carbon-neutral energy source
