Wind Power

What is Wind Energy?

• Conversion of kinetic energy of the wind into mechanical movement or electricity.

History of Wind Power

• World was explored on wind powered ships.

Wind Power

• Windmills grind grain.

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 (2)

• 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 require land.• can be noisy.• are unsightly.

Disasters

• Habitats are reduced.

• Many wild birds are killed by wind generators.

• Rare birds may be wiped out.

They Kill Birds Every Day!

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

• Modern aerodynamics and engineering have improved wind turbines.

• They are becoming more cost effective.

• Canadian Tire sells several types for individuals.

Economic Impact

• Generating electricity with diesel generators can range from $0.25 to $1.00 per kilowatt hour.

Economic Impact

• The current rate Hydro Quebec charges is .067¢ per kilowatt hour.

• The rate across Canada averages between .06¢ and .08¢ per kilowatt hour.

Economic Impact

• The cost of generating electricity ranges between five and ten cents per kilowatt hour.

Reflection

• Due to increased demand for energy nationally and internationally, something must be done.

• Wind power is an option that is becoming increasingly economically viable for the average person.
