Benefits to Global Energy Consumption
- Wind energy is to supplement other modes of power generation
- Clean and renewable/sustainable
- Never run out of wind – production of wind energy does not result in any form of solid, liquid, or
gaseous emissions or residues: no CO2 or toxic fumes are emitted - It does not deplete any form of fuel
- Once installed, it is easy and inexpensive to maintain
- Offshore installations becoming popular
Wind is a form of solar energy
Winds are caused by the uneven heating of the atmosphere by the sun, the irregularities of the earth’s surface, and rotation of the earth. Wind flow patterns are modified by the earth’s terrain, bodies of water, and vegetation Wind is formed when hot surface heat the air making it to rise. The cooler air moves into empty space creating wind

Estimates
- 22% of world’s electricity generation by wind power in two decades (Global Wind Energy Council)
- 28% of all new power generation built in the United States since 2009 has come from wind
How a wind turbine works
Basic parts:
- Blades (B)
- Rotor (A) – which rotate when the wind blows
- Shaft (C)
- Gearbox (D) to adjust for the speed of the wind
- Generator (G), which generates the electricity
Wind Power
Wind can provide 40 times current worldwide consumption of electricity, 5 times total global use of energy in all forms
