WIND POWER - What is it?

All renewable energy (except tidal and geothermal power), ultimately comes from the sun

The earth receives 1.74 x 1017 watts of power (per hour) from the sun

About one or 2 percent of this energy is converted to wind energy (which is about 50-100 times more than the energy converted to biomass by all plants on earth

Differential heating of the earth’s surface and atmosphere induces vertical and horizontal air currents that are affected by the earth’s

rotation and contours of the land WIND. ~ e.g.: Land Sea Breeze Cycle

LARGE TURBINES:

• Able to deliver electricity at lower cost than smaller turbines, because foundation costs, planning costs, etc. are independent of size.

SMALL TURBINES:

Local electrical grids may not be able to handle the large electrical output from a large turbine, so smaller turbines may be more suitable.

• Wind power generators convert wind energy (mechanical energy) to electrical energy.

• The generator is attached at one end to the wind turbine, which provides the mechanical energy.

• At the other end, the generator is connected to the electrical grid.

• The generator needs to have a cooling system to make sure there is no overheating.
