Wind Energy BY: Zach b; Josh k; Ella f; Gaby g; and Isaiah s.

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. How does a wind turbine work -- Gaby

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. Assimilate—Josh

The benefits of energy is that wind energy is a renewable resource. Also wind energy is clean and green. Benefits 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. The consequences of wind energy-- Isaiah

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.

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! Limit--Josh

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. Where’s the best place to put a wind turbine?—Gaby

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. Materials for Wind Turbines--Ella

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.

Wind energy can work with other forms of energy, Example wind energy can work with electricity by powering electricity. What energy sources work with wind energy-- Isaiah

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. Wind Pollution--Ella
