Wind Energy
• But in the beginning. What the meaning of the
word winds ?
• Wind is the movement of air from an area of high
pressure to an area of low pressure. In fact, wind
exists because the sun unevenly heats the surface
of the Earth. As hot air rises, cooler air moves in
to fill the void. As long as the sun shines, the wind
will blow.
