Wind Energy

SUN… The Power House
Earth receives 1.74 x 10^14 KW from the sun
Renewable energy
The free energy in nature
Non-Renewable energy
The energy from fossil fuels

What is WIND ?
Temperature differences drive Air circulation
North Pole South Pole Equator

Coriolis Force
Geostrophic wind
Sub Geostrophic wind
Local wind
Sea Breezes
Land Breezes
Mountain winds

Energy in the wind
Converting the kinetic energy of the wind into a torque, that puts a prime mover into motion.
