Question
Agricultural and forest residues are used to harness
- biomass energy
- wind energy
- thermal energy
- ocean energy
Hint:
Agriculture and forest residues are used to harness biomass energy.
The correct answer is: biomass energy
Agricultural and forest residues are used to harness biomass energy. The agricultural waste like cow dung and vegetable waste is stored in compost pit. The waste is degraded by bacteria and in this process Biogass( a mixture of CH4 and other gases) is obtained which is used as cooking gas.
