ABSTRACT

Energy demand in agriculture, industrial, commercial and household sectors has increased tremendously and placed enormous pressure on its resources. The economic growth level of any nation will be indicated by the availability and consumption levels of energy. India’s substantial economic growth is placing enormous demand on its energy resources. The energy sources that are not available in the commercial market for a price are classified as non-commercial energy. Non-commercial energy sources include fuels such as firewood, cattle dung and agricultural wastes, which are traditionally gathered, and not bought at a price used especially in rural households. Renewable energy is the energy obtained from sources that are essentially inexhaustible. Examples of renewable resources include wind, solar, tidal and hydroelectric. Conversion of biomass into energy is undertaken using two main process technologies namely thermochemical and biochemical. Thermo chemical conversion process includes combustion, pyrolysis and gasification whereas biochemical conversion process includes anaerobic digestion and fermentation.
