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

What We Use Now

• Most Buildings and entire cities are powered by oil, gas, or coal.

Air Pollution

• Oil, gas, and coal powered factories.

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.

Energy Solution

• Alternative energy sources

• There are many energy sources besides gas, coal, and oil.

Wind Farms

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

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.

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).

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.

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.

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.

“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.

Flaws of Wind Power

• Big and bulky so cannot be in certain places.

• Devastating effect of bird population

How They Work

• Wind Turns Blades

• Spins shaft

• Connects to generator

• Creates electricity

Why Wind Farms Should Be Used

•Clean

•Renewable

•Reliable

•Affordable

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.

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.

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.

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.

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.

In Conclusion

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

In Conclusion

Lastly, It is our responsibility to protect our

planet.
