WINDWIND

An estimated 1% to 3% of energy from the An estimated 1% to 3% of energy from the Sun that hits the earth is converted into Sun that hits the earth is converted into wind energy. wind energy.

The principle of wind is simple. The poles The principle of wind is simple. The poles recieve less energy than the equater does recieve less energy than the equater does from the sun. Also land heats up and cools from the sun. Also land heats up and cools down more quickly than the seas. This down more quickly than the seas. This difference between the seas and the land difference between the seas and the land causes a global atmospheric convection causes a global atmospheric convection system. system.

THE PRINCIPLE OF A WIND THE PRINCIPLE OF A WIND TURBINETURBINE

The wind power can be gained by The wind power can be gained by making it blow past the blades that making it blow past the blades that will cause the rotor to twist. The will cause the rotor to twist. The amount of power transferred is amount of power transferred is directly proportional to the density of directly proportional to the density of the air, the area swept out by the the air, the area swept out by the rotor, and the cube of the wind rotor, and the cube of the wind speed. It can be found out by the speed. It can be found out by the following equation:following equation:
