      Bio-mass and hydro-electricity both are renewable sources of energy.
      • Bio-mass is derived from dead plants and animal wastes. Hence, it is naturally replenished. It is the result of natural processes. Wood, Gobar gas, etc. are some of the examples of bio – mass.
      • Hydro-electricity, on the other hand, is obtained from the potential energy stored in water at a height (Making dams). Energy from it can be produced again and again. It is harnessed from water and obtained from mechanical processes.

      Bio-mass is obtained from the dead plants and animals. It is a renewable source of energy. Examples of bio-mass sources of energies are wood, gobar-gas.

      Hydroelectricity is obtained from the potential energy of the stored water at a certain height. Water from a certain height is made to fall on the turbines of the generator resulting in electricity. Dams and reservoirs are used in hydroelectricity.

      Both bio-mass and hydroelectricity are renewable sources of energies.

      Biomass and hydroelectricity are different in many aspects. Hydroelectricity is generated using the kinetic energy from moving water, while the energy from biomass is generated by decomposition of farm waste. Since biomass is composed of organic compounds so energy from biomass results in air pollution. Hydroelectricity, on the other hand, is pollution free.
