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!

Turbines Tumble

Turbines Fail

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.

400W Wind Generator Canadian Tire Cost: $799 Can power: Lights Laptop Microwave Radio TV / VCR /DVD Cooler

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.

USA Price per Kilowatt hour 5.81¢ in Tennessee 12¢ in California ¢ in New York ¢ in Hawaii 20¢ in parts of California

USA Price 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.
