Presentation Transcript

  1. Photos AddedBackground AddedTransitions and Effects Added

  2. Transitions and Effects • These add flash to the presentation. • The students will likely use too many and often the effects do not make the PowerPoint better.

  3. Wind Power

  4. What is Wind Energy? • Conversion of kinetic energy of the wind into mechanical movement or electricity.

  5. HistoryofWindPower • World was explored on wind powered ships.

  6. Wind Power • Windmills grind grain.

  7. Advantages of Wind Power • The energy is: • renewable • infinitely sustainable

  8. Advantages of Wind Power (2) • Pollution free • No green house gasses • No waste products

  9. The system produces energy only when there is wind blowing. It produces relatively small quantities of energy. Limitations of Wind Power

  10. Disadvantages of Wind Power • Wind farms: • are large scale operations that require land. • can be noisy. • are unsightly.

  11. Disasters • Habitats are reduced. • Many wild birds are killed by wind generators. • Rare birds may be wiped out.

  12. They kill birds every day!

  13. Turbines Tumble

  14. Turbines Fail

  15. EconomicImpact The cost of wind energy is determined by: • the initial installation cost of the wind turbine.   • the interest rate on the money invested.  • the amount of energy produced. 

  16. EconomicImpact • Modern aerodynamics and engineering have improved wind turbines. • They are becoming more cost effective. • Canadian Tire sells several types for individuals.

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

  19. EconomicImpact • The current rate Hydro Quebec charges is .067¢ per kilowatt hour. • The rate across Canada averages between .06¢ and .08¢ per kilowatt hour.

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

  22. 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.
