“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 fourturbine 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

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 toxins
into the air or leave behind waste.
• Fossil fuel energy releases
such as coal power CO2, causes smog,
acid rain, soot, and contributes to the
climate 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 anywhere
with 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.
