  2. 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 theRead more

    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.

  5. Wind energy is trapped using windmills. One of the limitations of the wind energy is that the windmills requires a speed more than 15 km/h to generate electricity. And the number of windmills will be more to cover a huge area.
