“Blowing in a New Direction” By Kevin Schneider & Jack Boyle

1. “Blowing in a New Direction”By Kevin Schneider & Jack Boyle

2. What We Use Now • Most Buildings and entire cities are powered by oil, gas, or coal.

3. Air Pollution • Oil, gas, and coal powered factories.

4. Dependency on Oil/Gas/Coal • Demand for oil/gas/coal is high. • Supply for oil/gas/coal is low. • Prices for oil/gas/coal are skyrocketing.

5. Energy Solution • Alternative energy sources • There are many energy sources besides gas, coal, and oil.

6. Wind Farms • A wind turbine is a rotating machine that converts the kinetic energy in wind into mechanical energy.

7. Wind Farms • If the mechanical energy is used directly by machinery, such as a pump or grinding stones, the machine is usually called a windmill.

8. Winds Farms • If the mechanical energy is then converted to electricity, the machine is called a wind generator, wind turbine, wind power unit (WPU) or wind energy converter (WEC).

9. Where should they go? • In order for a wind turbine to work efficiently, wind speeds usually must be above 12 to 14 miles per hour.

10. A New City Trend • Altamont Pass, east of San Francisco San Gorgonio Pass, near Palm Springs Tehachapi, south of Bakersfield • These wind farms can power San Francisco.

11. Long Distance Relationship • Once electricity is made by the turbine, the electricity from the entire wind farm is collected together and sent through a transformer. There the voltage is increased to send it long distances over high power lines.

12. “Show Me” Wind Farms • Following the opening of a new 5 mile long four-turbine wind farm, Rock Port, a town of 1,395 in North West Missouri, has become the first U.S. town to get all its electricity from wind power.

13. Flaws of Wind Power • Big and bulky so cannot be in certain places. • Devastating effect of bird population

14. How They Work • Wind Turns Blades • Spins shaft • Connects to generator • Creates electricity

16. Clean • Renewable • Reliable • Affordable Why Wind Farms Should Be Used

17. Cleanliness • Wind Turbines use simply the air in the environment to produce energy, not fossil fuels. • This means it does not release toxinsinto the air or leave behind waste. • Fossil fuel energy releasessuch as coal power CO2, causes smog,acid rain, soot, and contributes to theclimate crisis.

18. Renewable • Unlike fossil fuels and other energy sources, wind farms do not use up natural resources. • Wind turbines can always be rebuilt or repaired without harming the environment. • Wind farms can be added to anywherewith wind without depleting the land.

19. Reliability • Wind farms can be built easily • Wind farms can produce large amounts of power in strategically placed areas with high wind amounts. • New technology allows wind farms to produce energy even without large amounts of wind.

20. Affordability • Wind farms’ progress and growth are now allowing them to compete at a reasonable price with nuclear and coal power. • Wind power is far less expensive than middle east oil. • Wind farms produces energy on a constant and free resource, the air. • Scientists are STILL developing ways to make it less costly and more efficient.

21. Looking Ahead • Alternative energy is the way of the future, greatly wind energy. • Gasoline usage is projected to be gone within the next 100 years. • With the continuing threat of global warming, old ways of producing energy have changed.

22. In Conclusion • Wind farms help to contribute to the to get away from dependence on foreign countries.

23. In Conclusion Lastly, It is our responsibility to protect our planet.
