NEET BIOLOGY

Detailed explanation-1: -Direct combustion is the most common method for converting biomass to useful energy. All biomass can be burned directly for heating buildings and water, for industrial process heat, and for generating electricity in steam turbines.

Detailed explanation-2: -There are three ways to release the energy stored in biomass to produce biopower: burning, bacterial decay, and conversion to gas/liquid fuel.

Detailed explanation-3: -Burning either fossil fuels or biomass releases carbon dioxide (CO2), a greenhouse gas.

Detailed explanation-4: -For biomass fuels, the most common feedstocks used today are corn grain (for ethanol) and soybeans (for biodiesel). In the near future-and with NREL-developed technology-agricultural residues such as corn stover (the stalks, leaves, and husks of the plant) and wheat straw will also be used.
