Ok here ya go!\n\n In 2005, worldwide capacity of wind-powered generators was 58,982 MW, their production making up less than 1% of world-wide electricity use. Although still a relatively minor source of electricity for most countries, wind power generation more than quadrupled between 1999 and 2005.\n\nMost modern wind power is generated in the form of electricity by converting the rotation of turbine blades into electrical current by means of an electrical generator. In windmills (a much older technology) wind energy is used to turn mechanical machinery to do physical work, like crushing grain or pumping water.\n\nWind power is used in large scale wind farms for national electrical grids as well as in small individual turbines for providing electricity in isolated locations.\n\nWind energy is abundant, inexhaustible, widely distributed, clean, and mitigates the greenhouse effect.\n\nAn estimated 1 to 3 % of energy from the Sun that hits the earth is converted into wind energy. This is about 50 to 100 times more energy than is converted into biomass by all the plants on earth through photosynthesis. Most of this wind energy can be found at high altitudes where continuous wind speeds of over 160 km/h (100 mph) occur. Eventually, the wind energy is converted through friction into diffuse heat all through the earth's surface and atmosphere.\n\nThe origin of wind is simple. The earth is unevenly heated by the sun resulting in the poles receiving less energy from the sun than the equator does. Also the dry land heats up (and cools down) more quickly than the seas do. The differential heating powers a global atmospheric convection system reaching from the earth's surface to the stratosphere which acts as a virtual ceiling.\n\nThe change of seasons, change of day and night, the Coriolis effect, the irregular albedo (reflectivity) of land and water, humidity, and the friction of wind over different terrain are some of the factors which complicate the flow of wind over the surface.

Hi, see link... sorry for the canned response...\n\nhope it helps

If it is for a science project, web sites may or nmay not have the answers....that is all part of a project, to figure it out for yourself, develop your own theories, hypothesis, etc.\n\nI will say it all depends on the temperature....beyond that you're on your own.

i think that if you categorise it  under physics/biology/chemistry, you might get a better response.\n\nnevertheless:\n\nhttp://school.discovery.com/homeworkhelp/bjpinchbeck/bjscience.html
