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.

Is 'the wind howling outside the car' a personification?
Yes. Wind is the subject being personified and howling is the human trait assigned to the subject.
Personification - A figure of speech in which inanimate objects/non human are given human qualities
A windmill is a machine with sails or blades, usually four, driven by the wind, originally used to pump water, or grind grain,
Windmills were originally just that, a wind-powered grain mill (to turn grain into flour). Many "windmills", for instance those scattered around the Australian outback, are actually "wind pumps" to bring water from to the surface from deep underground.
Modern ones are used on wind farms that use the renewable source of energy, wind, to make energy.
What are the parts of a windmill?
The simplest part of a windmill are the rotor blades, generator and the shaft. but there are many parts when it comes to wind turbines. hope this helps!
How much energy is being produced using wind technology?
we can not tell how much wind is bein produced
How has wind technology affected the lives of the people who use it?
The overall effect in minor but it does have an effect.One being due to its structure it affects the surrounding area.
Yes.
There is some pollution and carbon dioxide emitted in the manufacture of the turbines, but once they are installed they are very easy to maintain and they produce electricity without any of the harmful byproducts of fossil fuel power stations.
What power scope should you use on a 30-06 and on a 308?
First you have to know what you are shooting. Then you have to know how close you plan on getting to the victim. If it's a bear, you want to be close range, so you don't need a high powered scope. If you are hunting deer from three hundred yards away, you'll need the best scope you can get. There is no set number depending on what gun you have, it's all about what you are shooting. Since both calibers are very versitile, you might want to get a variable power scope. I have a Winchester 1917 30-06 with a 4X~ 12X that works over a wide range of applications.
Is using ceiling fans and the air conditioner at the same time cost efficient or a waste of energy?
Regards,
Be-Cool Expert
Ceiling fans are definitely not a waste of energy.
Ceiling fans use very little electricity. Use them to circulate air in the house, to make the house feel cooler. By doing this, the thermostat setting for your air conditioner can be raised to 85°F, and still maintain the same comfort as the lower setting.
[From The Home Energy Saver a webpage from the Berkeley Lab website.]
If you only use ceiling fans in the rooms that you are in, then it will save a bundle. Just remember to turn the fans off when you leave a room. You can also buy motion sensors that will turn lights or fans on automatically.
Why are wind farms built in Northern Ireland?
As Ireland is on the west of Europe and the edge of the Atlantic Ocean, it gets a lot of wind, particularly along the west coast, so it is ideal for setting up wind turbines. There are many wind turbines around Ireland, with lots more planned.
What usually flow in the upper troposphere from west to east for thousands of kilometers?
the jet stream
How do you use wind energy in a home?
You can use wind energy for running energy around the house!!!!!!
How many wind turbines does it take to power Wellington?
well the total consumption of earths power on average sofar a year is 15TerraWatts of power, although this increases each year. the average output per year for 1 turbine is 0.35MegaWatts so that would mean, roughly 45000000 (fouty five million) wind turbines could more than power earths entirety (43Million is more than enough) even with 43 million there would be lots going to waist.
Now the total cost of all this would be 460trillion dollars, which is not that much. it would be affordable if 10 or 20 of the worlds most wealthiest countries, gave a decent wack of money from their annual incomes (not that much tho) so like 25 of countries gave a 20 trillion dollar donation. (they make way more each year. its affordable, and will give too many benefits for it to be a rip off.
J.T.
There is a little bit of problem with your calculation:
460trillion $ is more than 6years of the world gdp.
Right now"2012" there is no country have more than 16trillion $gdp.
1:EU 16trillion$
2:US 15trillion$
3:Ch 6trillion$
The cheapest way to deal with this problem:

A gas turbine extracts energy from a flow of hot gas produced by combustion of gas or fuel oil in a stream of compressed air. It has an upstream air compressor (radial or axial flow) mechanically coupled to a downstream turbine and a combustion chamber in between. "Gas turbine" may also refer to just the turbine element. Energy is released when compressed air is mixed with fuel and ignited in the combustor. The resulting gases are directed over the turbine's blades, spinning the turbine, and mechanically powering the compressor. Finally, the gases are passed through a nozzle, generating additional thrust by accelerating the hot exhaust gases by expansion back to atmospheric pressure. Energy is extracted in the form of shaft power, compressed air and thrust, in any combination, and used to power aircraft, trains, ships, electrical generators, and even tanks.

The sun.
AnswerI think it depends on the season. For example if it was winter it comes from the north and summer from the south. ANSWER:Wind is simply air moving to an area of lesser pressure. If you have a balloon full of air and you release the nozzle, air escapes out of the balloon which is under pressure to an area of which is less pressure. During cold or warm fronts you have a storm system moving in to areas of lower pressure and wind is the result. Another example is when the sun warms the earth, warmed air will rise and when this air goes up in a vertical direction, it creates an area below it that will be replaced by the air around it. This makes the air move in the direction of the rising air. To get a visual of this, Take an object and dip it into water. Pull the object straight up and the water will move to replace the area once occupied by the object. Air works the same way.How many wind turbines are needed to make a wind farm?
The largest individual wind turbine available today is the Enercon E-126 costing $3.5 million, which can generate about 20 million kilowatt hours per year.
The electricity consumption of the USA is approximately 3,892,000,000,000 kWh/year, therefore, assuming only these turbine were used, and they were sited suitably to receive an appropriate spread of wind over them throughout the year, the number of turbines required would be 194,600. Which would bring the total cost to $681,100,000,000
Answer
The above answer is a great start! There are a few missing elements though. Wind systems are never able to receive wind consistently. Typical wind averages are closer to 5 to 10%. That multiplies the number by ten. Additionally, the grid itself consumes massive amounts of power. Which would more than double the number again. Multiplying the above number by twenty would be a start point. That also assumes that all units would work at all times and that backup fossil fuel plants would be available and idling.
Is wind energy less expensive than nuclear energy?
Wind power can be quite costly over time, but nuclear power creates wastes that cost a lot of money to dispose of, let alone getting the nuclear rods in the first place. However, nuclear power can provide much more power than wind power, so they are more or less equals.
Why some renewable resources aren't widely accepted today?
some are dangerous ,cost alot of money or are developed technology
Why are there lots of wind turbines in a wind farm?
Modern windmills and wind turbines are equipped with devices that turn the blades to face into the wind.
Why are offshore wind farms a good idea?
Because they can produce electricity, without dangerous and polluting Carbon dioxide emissions. However, studies have shown that wildlife can be harmed by them, especially migrating birds. Having them offshore means that people can't complain about their noise.
How does a windmill turn the sun's energy into electricity?
causes the air to flow from one place to another, in a type of behavior that
we call "wind". Since the air is moving, it has kinetic energy. The windmill
intercepts some of the moving air and robs part of its kinetic energy.
