Explain sun as non-conventional source of energy.

Explanation

The sun has been radiating an enormous amount of energy at the present rate for nearly 5 billion years and will continue radiating at that rate for about 5 billion years more.
Only a small part of solar energy reaches the outer layer of the earth.s atmosphere. Nearly half of it is absorbed while passing through the atmosphere and the rest reaches the earth.s surface.
Many of the sources ultimately derive their energy from the sun.
Solar energy is inexhaustible source. It can be used in appliances such as solar cooker, solar water heater, solar cell panel, etc.
India receives solar energy for greater part of the year. India receives solar energy `gt` 5000 trillion kWh, i.e., daily average 4 to `7 kWh//m^(2)` under clear sky conditions.
