Energy from various sources is considered to have been derived from the sun. Do you agree? Justify your answer.

Energy from various sources is considered to have been derived from the Sun. This statement is correct because Sun is the ultimate source of energy because most of the energy resources derives their energy from the Sun such as bio mass, ocean thermal energy and ocean energy etc. Ocean thermal energy is produced by heating of water surface by Sun which results in difference in temperature which can be used for production of energy. Similarly, unequal heating of landmass and water bodies results in air movement and causes blowing of wind. This wind is then used in windmills to produce electricity by moving the turbine of generator. So, Energy from various sources is considered to be derived from Sun.
