Answer 1

Answer:

Solar energy

Explanation:

Solar energy is renewable and a very cheap energy source that can easily be harnessed for a wide range of uses domestically and industrially.

Solar energy is sourced from the sun. Nuclear fusion within the sun releases a massive amount of energy into the solar system. The sun furnishes the solar system with insolation which can be used by living organisms and can be converted to other sources of energy.

This energy source is free and very much available almost all year round.
