“Wind power” is nothing but the successful conversion of wind energy into something other useful form, usually electricity by using wind turbines specially designed long blades, shaped such that they can capture the rushing wind and rotate providing for mechanical motion.
It was reported in the year 2005 that the world’s wind power capacity was about 60000 megawatts, constituting about 1% of the world’s present electric power usage. Although not much of this renewable energy is used in the U.S, countries like Denmark and Spain make use of this technology to contribute, in quite respectful doses, to their electrical energy needs.
Modern electric power is generated by converting the rotary motion of the turbines, caused by the wind, into electrical energy by the means of a electric generator. Wind power is used to provide electricity ranging from huge wind farms to stand-alone mills to provide energy for isolated places.
It also has to be noted that wind energy is renewable, abundant, mitigates the greenhouse effect, contributes nothing to the air pollution and is reasonable easy to produce. The cost of producing wind power has tumbled down considerably over the time. It is worth mentioning the fact the amount of wind power being produced in the U.S alone has seen growth rates of about 15 to 20%.
About 1 to 4% of the solar energy is converted into wind energy, while most of it is again absorbed by the vegetation for photosynthesis; the rest of it keeps rushing about at high altitudes and low-altitudes with varying velocities and intensities. The power of the wind is captured by letting it flow past the turbine blades which in turn induce a torque in the motor attached. The amount of power generated is proportional to the density of air, the area swept by the rotor and the cube of the speed of the wind.
Higher velocities of wind cause more power to be generated, however, all locations no not all always have winds blowing at the same speeds or velocities. It has been noticed that the power is averaged out and most of the windmills capture power in short wind bursts.
Wind power is quite a popular way to economize on the energy costs and most customers in the U.S can opt for some utility power service providers and subscribe to power from these forms of new alternative sources of energy mostly wind energy.

Alternative energy resources? solar power, wind power, hydroelectric power?
I am giving a presentation on alternative energy and need to find a good source of statistics, graphs, charts, diagrams etc to use. specifically, i will be referring to hydroelectric, wind and solar power.
thanks for your help in advance
answerer 1, you need to chill out…its for college. im not an oil barren you dodger
A graph of how much revenue oil barons and the refining process would lose in relation the % of renewable energy as a total of energy production would be the most pertinent in modern society.
Yes we think that you huge businesses should stop your hugely profitable exploits and instead spend billions investing in renewable energy. Afterall it’s only money isn’t the planets more important and I am sure you didn’t become Oil barons because you are incredibly selfish and want far more than everyone else even if it means millions have to starve and die and suffer.
People wake up stop your governments from supporting these people renationalise your power industry invest in research and maximise renewable energy. Or sit back and let them charge you interest on the loans your govenment takes to buy weapons that you manufacture to send your own people to die for their profit and finacial security.
Death to MYism long live WEism.

Here are three decent web sites that should give you plenty of information. They cover Solar, Wind and Geo Thermal. Being in the Midwest (and mostly flat lands) I don’t work to much with Hydro power. Good Luck with the paper. Look for ways to transmit these types of energy to the average home, the infrastructure is the key and where the US needs the most help. The one who finds the best way will make the most money, and do the most good for us and the world.

Hmmm… renewable sources of energy.
You will get all information you require.
Even you can make your own electricity through renewable sources.
