GENERAL KNOWLEDGE

Detailed explanation-1: -Wind energy is actually a byproduct of the sun. The sun’s uneven heating of the atmosphere, the earth’s irregular surfaces (mountains and valleys), and the planet’s revolution around the sun all combine to create wind.

Detailed explanation-2: -The Sun’s Energy for Winds The sun powers the wind by heating up our air. Different parts of the earth are closer to the sun depending upon the earth’s rotation (on its axis), so different areas of the earth will have warmer air. Also, different kinds of materials absorb the sun’s heat faster than others.

Detailed explanation-3: -The energy of the sun is the original source of most of the energy found on earth. We get solar heat energy from the sun, and sunlight can also be used to produce electricity from solar (photovoltaic) cells.

Detailed explanation-4: -Wind is used to produce electricity by converting the kinetic energy of air in motion into electricity. In modern wind turbines, wind rotates the rotor blades, which convert kinetic energy into rotational energy.
