1. The moving air spins the turbine blades.
2. The blades are connected to a low-speed
shaft. When the blades spin, the shaft turns.
3. The low-speed shaft is connected to a gear
box. Inside, a large slow-moving gear turns a
small gear quickly.
4. The small gear turns another shaft at high
speed.
5. The high-speed shaft is connected to a
generator. As the shaft turns the generator, it
produces electricity.
6. The electric current is sent through cables
down the turbine tower to a transformer that
changes the voltage of the current before it is
sent out on transmission lines.

•Only the
electricity wind
turbines create
can be stored not
the wind power
itself.
•The result is wind farms do not benefit portable energy.
•Wind power today is connected to existing city grids of
electricity to power homes, businesses, and city lights
•The largest turbines in U.S. can produce three to five MW,
enough electricity to power 900 to 1,500 homes.
 "The average tower generates
4,500 to 5,500 dollars per
year, and each tower takes up
less than an acre’. That's a
good return,“ said Stephan
Wilson from Xcel Energy.
 It’s Renewable
 U.S Department of Energy
says wind power has potential
to produce twice as much as
the energy demand.
 But, wind energy is most
suitable in rural areas (not big
cities)
 New Power lines would
need to be built.
 Cleaner (no pollution, no fuel)
 Cheaper (initial costs, but once
installed works great.)
 Small businesses are getting tax
breaks for using this renewable
energy(Through December 31,
2016, individuals can receive a 30
percent tax credit for installing a
 Small wind system, up to 100
kilowatts.
 Less money to construct than coal
or nuclear plant

Looks a little weird

Cause effect to wild bat population

Severe weather could potentially
damage turbines.(causing money to be
spent for repairs)

Unreliability will cause power plants to
remain open just in case.

 Very likely. It costs less and
it’s creating more production
then we are consuming so we
can store it for the future. Also
it’s completely renewable so
no fuel is being used to create
this energy.
 Khari Bell
 Not likely. It is a huge
economic venture to build
enough turbines and new
power lines to capture the
nation’s wind energy.
