Wind Energy

How does a wind turbine work -Gaby
When wind blows against the blades of a wind turbine, It makes the blades
turn.
The blades are usually connected to the main shaft or stand. So when the
blades turn the main shaft turns.
There’s a gearbox connected to the main shaft.
While small gears turn quickly causing the big gears to turn slowly. The gears
turn another shaft, called the high speed shaft.
The high speed shaft is connected to a generator. The generator is made up
of magnets onside coils of copper wire.
When the high speed shaft spins and the magnets spin, It creates an electric
current in the wire.
Thick cables carry an electric current or electricity out of the turbine.
The blades are connected to a shaft. By turning the blades, the wind will
rotate the shaft.
For centuries people have used wind energy to pump grain and water.
They are also used to produce electricity.
Assimilate—Josh
The blades are mounted on the rotor at a 45
degree angle. When wind blows, the rotor turns which
spins a gear very fast. The gear turns a generator and the
generator stores power in a battery. There is
also a part of the turbine called
anemometer and it measures where
the most amount of air is coming
from. It will give data to a
computer and the computer will
turn the nacelle toward the
direction of the wind.
Benefits of wind energy-- Isaiah
The benefits of energy is that wind energy is a renewable resource.
Also wind energy is clean and green.
The consequences of wind energy-- Isaiah
The wind mills cost a lot of money.
Also wind power can produce pollution but very little pollution.
Finally the last consequence of wind energy is the wind mills can kill
flying animals because the wind mill will be spinning and the birds or
bats will fly into the wind mill.
Cost--Zachary
The cost of wind power is sort of
expensive. To install the wind turbines it
cost between 10,000 to 13,000 dollars.
But eventually you will save money
because you don’t have to pay
electricity bills. If you have lots of wind
it is easier to power your electronics.
But if you don’t have lots of wind it takes
more power to power your electronics.
Limit--Josh
There is no limit to wind power-wind will
always be here as long as the sun warms the Earth,
but wind turbines can cause death to bats and birds,
so they may be taken away. Also, it is hard to find a
place to put the turbines, because they are so loud.
There are even cost limits-it costs 10,000 to 13,000
dollars to build a wind turbine. Another limit is that
you can not have too many of them in 1 place-they
will steal each others air!
Where’s the best place to put a
wind turbine?—Gaby
The best location fro a wind turbine is for it to be 30
feet above anything within 300 feet. Most people have
put the wind turbines on top of 30 to 40 high on
electrical poles. (Installed by your local electrical
company). You can actually get a turbine made higher
than 30 to 40 feet. You can do that by using a steel
extension, mounted to the side of a wooden electric
pole.
Materials for Wind Turbines--Ella
The materials for wind turbines is simple. The part are the blades, the
tower, gear box, and the main shaft. These parts are made from steel
or copper. The picture(s) below show where these parts go.
Efficiency--Zachary
Wind power is more efficient than
wind power because soon we will run out
of fossil fuel. But we will never run out of
wind. Also fossil fuel is very harmful. If we
humans release to much fossil fuel into the
air it makes it harder for us to breath.
What energy sources work with
wind energy-- Isaiah
Wind energy can work with other forms of energy, Example wind
energy can work with electricity by powering electricity.
Wind Pollution--Ella
Pollution is a big problem. Unfortunately wind can pollute. You see that if you
litter wind can carry it far away to the sea or any other place were animals
live. However we can fix this. You know how? By not littering! By doing this we
can help animals and wind energy.
