Wind Power
Wind power is derived from the conversion of wind energy to become a useful form of energy to propel ships, make electricity or pump water. Wind is a renewable source of energy that is widely available and produces no harmful emission during operation.

What does a power stations turbine do?
A power station's turbine converts steam energy into rotary energy to drive the generator.
What is the duration of a wind turbines life and how long can one work for in years?
A typical wind turbine lasts about twenty to twenty five years.
How much money do wind turbines save yearly?
Wind turbines save about 28.5 million dollars per year accumulatively for residences currently using them.
Why does winding road make it easier for vehicles to travel up a hill?
A winding road is an example of an inclined plane, or a screw. A screw is a simple machine that trades force off for distance.
How many watts does an eighty foot tall wind turbine produce?
The height of a wind turbine has no impact on the turbine's output wattage. The factors that effect the watts produced are:
* The efficiency of turbine design (this is at most 59%) * the density of the air * the radius of the turbine (that is, the length of each fin) * the velocity of the wind passing through the turbine An 80 ft tall turbine would presumably have a fin length (that is, turbine radius) of at most 30 ft. Thus, at sea level on a 59 degree (F) day, in an 8 m/s (18mi/h) wind, with the most efficient turbine design possible, you would generate approximately 15.4 Kilowatts.

How Do Wind Turbines Save You Money?
I think that a wind tuebine save you money because it is power by the wind
What is the disadvantage of swept back wing?
The surface area of the wing is slightly reduced, resulting in a reduced ability to generate lift. The effective aspect ratio is reduced, helping to increase wing tip vortices. Also, it is harder to recover from a stall with a swept wing aircraft, as the rear of the wing tends to stall first. This produces a greater nose up pitch on stalling, which is far harder to recover from than with a straight-winged aircraft.
How much wind energy is used in the us?
We are adding these systems daily and the United States produces more wind power then every other country.
They are will never provide any real power due to issues with there abilities, but they make people feel good about doing something. What that something is (unfortunately) is not good.
How much engy dose a wind turbine use?
A wind turbine can use up to 40kw/h of energy at once.
When for example the turbine is yawing into the wind (turning the head of the turbine into the wind for the blades to face the incoming wind). 4 high power motors and gears are used to do this. When at the same time the hydraulic system is turned on to control the blades to position themselves in the wind, and the motors for the cooling are enabled, the windturbine can require a lot of wind. However usually this is generated by the turbine itself. So this is not really relevant as the output is much higher then the usage.
How much money do you save while using wind energy?
One can save as much as $3.05 per kilowatt hour with the use of wind energy. If a household consumes 50 kilowatt hours per month, that makes $152.50 savings on a monthly basis.
What is the one important source of electric power in the desert?
Solar and wind energy are often power sources in the desert.
Where is the biggest wind farm?
- Horse Hollow Wind Farm in Texas, USA is the wind farm with the highest energy output of 662 MWatts/hr. When completed, it is planned to produce over 1600 MWatts/hr.
- So far, the world's largest wind farm is in Texas and it comprises some 100,000 acres of farmland. The complex has 627 turbines capable of generating enough electricity to power 230,000 homes. The over $1 billion project, involved negotiations with 300 landowners and has a wide variety of turbines made by Mitsubishi, General Electric, and Siemens.
- As of May 2008, T. Boone Pickens is planning to build a wind farm to produce over 4000 MWatts/hr -- again in Texas -- on land leased from local ranchers and farmers.
- Overall, Spain leads the world in per capita wind power. They provide 40% of their country with electricity from wind.
- Built in California USA, the British royal family owns the largest wind turbine called "The Britannia" with a 492 ft diameter and 7.5 MWatts/hr of output.
How much of the world's energy comes from solar power plants?
A very small percentage so far, 0.05%. However, scientists and the public are looking to have more of the world's energy come from solar power plants.
"Solar power...would represent the annual output from 150 coal-fired power plants" by 2025, the European Photovoltaic Industry Association (EPIA) and Greenpeace said. The report said photovoltaic systems, which turn sunlight into power, now generate 0.05 percent of world electricity and could rise to 2.5 percent in 2025, the main horizon for the report, and then leap to 16 percent in 2040.
Not many people know this, but solar, wind, and electricity only account for less than 1% of the worlds energy combined.
How many people does it take to build a wind turbines?
It takes about over 500 people to build a turbine wowza!
Currently, the world is heavily dependent on fossil fuel. But we might soon run out of it, and the amount of pollution it is creating is also alarming.
The future of energy sources lie in the non-conventional sources of energy, most importantly solar, wind and tidal energy. Also alternative forms of energy like Hydrogen and BioAlcohol based fuels are close short term alternatives to reduce the dependency on fossil fuel. They produce little or no carbon di oxide, and are cheaper to generate too.
What percent of wind energy is used in the US?
The Percentage of wind energy consumed in the U.S.A is about 2%
One example of wind is sea breeze. This type of wind is a cool breeze that is created over land that are near coasts. Another example is the mountain and valley breeze which occur one after the other. The third example is the chinook wind. It is a dry type of wind. It is simply known as chinooks.
Different ways of producing electricity?
There are multiple means to electricity production. These include hydro, nuclear (fission), geothermal, wind, solar, and coal & natural gas fired generating stations. Fusion is still experimental but bear promise as an ultimate form of energy if it can be harnessed.
