History of Wind Power
• World was explored on wind powered ships.
Wind Power
• Windmills grind grain.
Wind Power
• Ancient Persians pumping water
Advantages of Wind Power
• The energy is:• renewable• infinitely sustainable
Advantages of Wind Power (2)
• Pollution free
• No green house gasses
• No waste products
Limitations of Wind Power
• The system only produces energy when there is wind blowing.
• It produces relatively small quantities of energy.
Disadvantages of Wind Power
• Wind farms:• are large scale operations that require land.• can be noisy.• are unsightly.
Disasters
• Habitats are reduced.
• Many wild birds are killed by wind generators.
• Rare birds might be wiped out.
Economic Impact
The cost of wind energy is determined by:
• The initial cost of the wind turbine installation.
• The interest rate on the money invested.
• The amount of energy produced.
Economic Impact
