WIND
POWER
IF AN AIR MASS GETS WARMER THAN ITS CURRENT STATE,
IT RISES UPWARD TO THE ATMOSPHERE AND WHEN THIS AIR
MASS IS INCREASED, THE MASS OF COLD AIR IS PLACED IN
THE SAME VOLUME. THE DISPLACEMENT OF THESE AIR
MASSES IS CALLED WIND. WIND ENERGY IS THE MOVEMENT
ENERGY OF THE AIR FLOW THAT CREATES THE WIND. THE
SOURCE OF WIND ENERGY IS THE SUN. 1-2% OF SOLAR
ENERGY IS CONVERTED INTO WIND ENERGY.
