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.

Why are wind turbines built the way they are?
They are built so they have the maximum area possible to pick up wind, and the best quality so they last long, for the lowest price, so they are cheap to make. They have huge fan blades, that are tilted at the perfect angle.
What are the disadvantages of wind power?
Disadvantages of wind power:
- The strength of the wind is not constant and it varies from zero to storm force. This means that wind turbines do not produce the same amount of electricity all the time. Luckily, wind energy isn't produced in isolation. It's added to widely connected energy grids with 24 hour spot energy markets. It's added to grids that span thousands of kilometres and have many types of generation and demand. Up to about 20% of a grid's generation capacity, it requires very little backup.
- Some people see large wind turbines as unsightly structures and not pleasant or interesting to look at. They believe that wind turbines degrade the landscape.
- Wind turbines generate noise. A subset of people who live near wind turbines find this noise annoying. A subset of those people get stressed by it. Wind turbine noise does not make people sick.
- Birds are killed by wind turbines. Studies show that wind turbines do not threaten the vast majority of bird species populations. Killing birds, in other words, does not threaten birds generally. That said, wind turbines should not be sited on raptor migration routes, as the Altamont wind turbine farm was. The best evidence is that song birds migrate at 2000-4000 feet, far above wind turbines and sea birds avoid them according to radar and thermal studies of North Sea wind farms.
- Bats are also killed by wind turbines, due to barotraumic stress (the reduced air pressure behind a wind turbine blade is damaging to bat's lungs and heart). However, bats are not killed in significant numbers compared to their populations by wind turbines. Bats are, however, killed in significant numbers in North America by white nose syndrome (300,000 in one cave alone.)
What is the big machine to produce energy from wind?
The big machine used to produce energy from wind is called a wind turbine. Wind turbines have large blades that turn when the wind blows, generating electricity through a rotor connected to a generator. This clean and renewable energy source is used to power homes, businesses, and communities.
Is the boy who harnessed the wind a biography?
The book is actually an autobiography, or a memoir. It is the life story of William Kamkwamba, as told by himself and co-author Bryan Mealer.
They do. Who told you they didn't? Wind turbines have been installed on many airplanes. In particular, the A3 had a RAT (ram air turbine) that was extended if emergency electrical power was needed.
Great question!
Wind farms are funded, in general, by different types of investors according to stage of development, construction or commissioning. Investors that invest in projects still in development (pre-construction) tend to be high net worth individuals or larger developers seeking to add projects to their pipeline.
As a wind farm approaches its perfected, construction-ready stage it becomes attractive to equity investors, who provide approximately 30% of total construction costs as project equity. Equity investors can be high net worth individuals. They can also be large funds our utilities seeking to own and manage clean, renewable energy projects. The remaining 70% of construction costs are provided by a short term debt lender such as a bank. Once the project has been commissioned, long term lenders, also banks, take out the short term debt.
Why would you use wind rather than coal as an energy source?
because coal pollutes and we have unlimited wind
wind farms provide electricity. Wind farms cost more to maintain and construct than the energy that they provide. In addition they very inefficient because they only work when there is wind.
Who does the government think about wind farm?
Ever so slowly, the federal government is starting to support wind farms, for example, approving the off shore wind farm near Cape Cod, Massachusetts.
How wartsila abb amg 1600 produce electrical energyand the generator operate?
the prime mover rotates the rotor of the alternator. the exciter contains stator coils with remanence induces voltage in the rotating windings of the exciter rotor which is then rectified and goes through the main field winding. the rotating rotor flux cuts through the stator windings inducing voltage on them. the AVR controls the field current to the exciter stator coils. DC current for pole formation.
How is wind energy used in Canada?
As a means of pumping water and generating electricity in remote locations, wind power has a history in Canada dating back many decades, particularly on prairie farms. At the end of 2011, wind power generating capacity was 5,265 megawatts (MW), providing some 2.3% of Canada's electricity demand. The Canadian Wind Energy Association has outlined a future strategy for wind energy that would reach a capacity of 55,000 MW by 2025, meeting 20% of the country's energy needs.
Alberta built the first commercial wind farm in Canada in 1993. British Columbia was the last province to add wind power to its grid with the completion of the Bear Mountain Wind Park in November 2009. With increasing population growth, Canada has seen wind power as a way to diversify energy supplies away from traditional reliance on fossil fuel burning thermal plants and heavy reliance on hydroelectricity in some provinces. In provinces like Nova Scotia, where only 12% of electricity comes from renewable sources, the development of wind energy projects will provide a measure of electricity security that some jurisdictions are lacking. In the case of British Columbia, wind energy will help close the electricity deficit that the province is facing into the 2010s and help reduce the reliance on importing power from other jurisdictions that may not use renewable energy sources. An additional 2,004 megawatts of wind power is to come on stream in Quebec between 2011 and 2015. The new energy will cost 10.5 cents per kilowatt-hour, a price described as "highly competitive"
Where in the US is wind power used?
Massachusetts.
Also Nebraska and the Midwest in general - and there is also a windfarm in Texas
Difference between captive power plant and independent power producer?
When there is a huge demand of power and people feel generating electricity is cheaper than purchasing it, Captive power plants are made. Excess generation of CPP can be sold through grid.
On the other hand Independent power plants are made for supplying to grid only.
When is hydrogen expected to be easily accessible to the general public?
It is currently very easy to obtain. Local welding supply or gas supply companies offer hydrogen in T bottles. Almost all of the hydrogen currently available is stripped from natural gas, so the cost is fairly low.
What farm can be used to generate electricity?
a solar farm can be used to generate electricity.
for example if you had a wind mill or water wheel.
