(i) Direct utilization of solar energy
The direct utilization of solar energy can be done either by collecting it as heat or by converting it directly into electricity.
Examples: Solar cooker and solar water heater uses this type of utilization of solar energy.
(ii) Indirect utilization of solar energy
The indirect utilization of solar energy can be done by converting it into chemical energy like the bio-mass of plants.
The other indirect ways of utilizing the solar energy are:
Harnessing the energy of the wind and utilization of energy of the sea-waves.
