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.

Solar panels can be used to generate a portion of your home's power in order to reduce your dependency on traditional power sources. For instance, you can install panels to provide electricity just for appliances or lighting, to reduce your dependency on the utility company, as well as lower your bill.
A wind farm is a large area of land in which wind mills are spread out. The more they spin they more energy they generate, they generate energy when the wind is anyway between 12 - 75 Kmph.
What are the main problems associated with the use of wind energy?
It's just another form of energy, and there's nothing good nor bad about energy... it is what it is - just a force of nature.
However, if you mean what are the drawbacks surrounding renewable energy production from wind operated generators, then the biggest complaints against wind farms suggest that they are:
a) a blight on the landscape
b) noisey
c) costly to setup
d) an unreliable source (for the main grid)
Is wind energy an alternative resource?
Sailing boats, kites, washing lines and windmills have been around for a long time!
What is the environmental impacts of using wind power?
Advantages: virtually zero pollution and little use of non-renewable resources (except, of course, for the manufacture of the equipment and maintenance). Disadvantage: output depends on the weather and is therefore not always available when needed; therefore, conventional sources of electricity are still needed as backups.
What is the energy transformation involved for a wind turbine?
Starting at the sun and going to the output electricity:
- Solar energy is produced by nuclear fusion (Nuclear fusion--> heat and electromagnetic energy)
- Solar energy warms the soil and air of the Earth (Radiant energy-->heat)
- Temperature differentials create wind. (thermal energy to molecular movement, molecular movement and gravity--> kinetic energy as air movement)
- Wind moves the blades of the turbine (kinetic energy-->kinetic energy)
- The spinning blades move magnets in a coil of wire (kinetic energy-->kinetic energy)
- A coil moving in a magnetic field creates electricity (magnetic energy-->electricity)
Why is wind energy a good way to generate electricity?
It is a good way, because...
A) It decreases our dependence on OPEC,
B) It decreases our dependence on Arab countries,
C) It decreases our dependence on the increasingly expensive foreign oil,
D) The wind mill process is cleaner than burning coal,
E) The wind mill process is cleaner than burning oil, and
F) Over time, the value of wind mill generated electric power is greater than the investment we need for setting up and maintaining wind mills.
What are the waste by-products of wind energy?
The waste products of wind energy are those that result from the manufacture, transportation, installation, maintenance, removal, and disposal of the wind generation equipment. They include carbon dioxide, various chemicals, and so on, but they are very small compared to products of other sorts of electrical generation equipment. They have no particularly special dangers and include no products that are especially hazardous.
When the wind turbines are up and running there are no waste byproducts, no carbon dioxide, no pollution. Just clean green energy and dead birds and bats.
The real pollution is still present though at fossil fuel plants that are ran to subsidize the variables of wind energy. Fossil fuel plants running, at idle, are still producing the same CO2 as if they were connected to the grid, but the cost is ignored only because the energy is not used.
How much energy can one wind turbine generate in one day?
Law of physics . . . energy cannot be made, and for that matter, cannot be destroyed. The only thing that you can really do with energy is to change it into a different form.
So, wind generators turn energy in the wind into energy in the form of electricity and a bit of heat. Power output is how wind generators are measured. Power size gives us an idea of how much work can be done by the electrical energy that wind generator put out. Wind generators come in many sizes (of power), from 'backyard' to huge wind farm sizes.
What is the wave power impact on the environment?
lol I am biased towards the positive effects. Wave power is clean and has large potential for places with long coastlines, such as New Zealand. The systems are usually moored out to sea, so should not effect recreational use of the ocean greatly. Environmentally, there is little to worry about, since the hydraulic oils used can be biodegradable. On the negative side - maybe some dumb fish could get mashed up. Also, some people have been known to mistake wave energy systems for overturned boats. lol
Does wind power have any pollution?
Manufacturing a turbine will cause some pollution, assembling, erecting and connecting the turbine to the grid will cause some more. Servicing the turbine will also come at a certain environmental cost. Running the turbine will generate not only electricity but also noise, which some people refer to as sound pollution. But the everyday running of the turbine does not pollute. The fossil fuel plant that must run in tandem with the wind system will continue to produce the same volume of pollution and CO2 as before. Wind varies so the utilities leave fossil fuel plants run to compensate for this variance. Net result is zero reduction at the generation point(s) and an net overall increase in CO2 and pollution die to manufacture and maintenance.
When the public realizes this is a boondoggle, they will disappear.
What kind of energy is a windmill?
Windmill composed of 2 energies. One is the mechanical energy. To make it work the force of the wind allows the windmill to run and this process produces the second energy called the wind energy.
How much pollution does a wind turbine produce?
Very little or none at all, they're one of the greenest electricity source.
Are wind turbines harmful to your health?
Not usually, and not directly. But some wind turbines are noisy, and if someone has a house nearby that does not insulate against sound very well, the noise may keep the residents from sleeping well. This in turn could cause health problems. ( The noise from traffic on a highway is much worse than the noise from a wind turbine.)
Can you please send to me Turbine parts and function of each part shortly?
How much does a wind farm cost to build?
Considering the fact that a 500MW coal-fired plant can cost upwards of $1 billion just for land acquisition and construction (not considering operational and maintenance costs or fuel costs), a wind farm with equivalent energy output, zero emissions and no-cost fuel (wind) comes in at about $600 million.
'Equivalent energy output' is incorrect. The original author is confusing 'installed capacity' - the power it could generate under ideal conditions - with output. This is a very important distinction.
For example, if you have 500MW of coal capacity and 500 MW of wind capacity, as long as you have optimal fuel for each system, they will output the same amount. In the case of coal, the operator can control the fuel supply (mostly) and run at any percentage of peak capacity for as long as is desired, up to 100% of the time. For wind, the operator is at the mercy of how much and how fast the wind blows and can only operate at peak capacity when conditions are perfect, which is less than 15% of the time. The concept is called 'capacity factor'.
Is weathering good for the environment?
NO, it is not good for the environment as it can destroy the earth and will reduce the capacity of water. Soil erosion can also led to land becoming barren as the soil slowly erodes away.
What is the salary for a wind turbine technician?
A wind technician's job can range from construction to maintenance and repairs on wind turbines. Some sources on AWEA's web site say that for every 10 wind turbines that are built, 1 new wind tech is needed for maintenance and repair. Reports of what they make vary. Some report a high hourly salary with a low per diem that totals around $65,000 per year on average in places with moderate costs of living in the U.S. Others report a medium salary with a high per diem that can total well north of $75,000 a year. Many employers also carry employee health insurance and issue a company truck for work related duties. As with everything, compensation depends on demand from employers which now appears to be high. If you would like more information on where you can go to get trained, do a google search for California Wind Tech or go to www.californiawindtech.com
How much do wind turbines cost in pounds?
The cost of solar panels and solar systems vary a great deal based on the size and usage of the panels and the size of the system installed. Based on what solar experts call the average home system, one could expect to spend around 6,000 pounds.
Which state has the most wind turbines?

How much does a wind turbine save you?
Wind turbines do not save any money. As of today, the overall cost of a kiliowatt of wind power is still higher than most other forms of energy. What wind is trying to save is the amount of fossil fuels we are using. Payback on wind is still not a feasible concept, although the numbers are getting better.
Where are the calm areas of winds belts?
Known as the Horse Latitudes 30 to 35 degrees both North and South of the Equator. Conditions are generally warm and dry
Same question on science work sheet,no clue???????????????????????????
