I know a little, but does anyone have a clearer idea? http://topicsofconcern.com/blog/wind-energy/how-does-wind-energy-work-i-know-a-little-but-does-anyone-have-a-clearer-idea http://topicsofconcern.com/blog/wind-energy/how-does-wind-energy-work-i-know-a-little-but-does-anyone-have-a-clearer-idea#comments Thu, 29 Oct 2009 19:12:20 +0000 admin http://topicsofconcern.com/blog/wind-energy/how-does-wind-energy-work-i-know-a-little-but-does-anyone-have-a-clearer-idea I’ve tried some internet sites, but none of them have given me any real idea of how it works except "It turns the blades and generates electricity"

I am really interested in Wind energy, and how it works. Anyone have a somewhat clearer explanation for me? Thanks.

Wind spins turbines which powers a generator. That’s the easy way to explain it. But if you want to know more in detail:

"Wind power is the conversion of wind energy into a useful form, such as electricity, using wind turbines. At the end of 2007, worldwide capacity of wind-powered generators was 94.1 gigawatts.[1] Although wind currently produces about 1% of world-wide electricity use,[2] it accounts for approximately 19% of electricity production in Denmark, 9% in Spain and Portugal, and 6% in Germany and the Republic of Ireland (2007 data). Globally, wind power generation increased more than fivefold between 2000 and 2007.[1]

Most wind power is generated in the form of electricity. Large scale wind farms are connected to electrical grids. Individual turbines can provide electricity to isolated locations. In windmills, wind energy is used directly as mechanical energy for pumping water or grinding grain.

Wind energy is plentiful, renewable, widely distributed, clean, and reduces greenhouse gas emissions when it displaces fossil-fuel-derived electricity. The intermittency of wind seldom creates problems when using wind power to supply a low proportion of total demand. Where wind is to be used for a moderate fraction of demand, additional costs for compensation of intermittency are considered to be modest.[3]"

Hope that helps you. :)

I am not interested in any other forms of alternative energy, so a general renewable energy bachelor’s won’t do. Any help?

But you will still have to include renewable energy in your searches because it is part of the whole gamut of a still wider and unfolding field … and so you will have to include in your searches solar energy and natural resources as well because, after all, the whole purpose of harnessing wind energy is to produce electricity and to support engineering involved in designing and manufacturing wind-availing technologies.

Look to those schools located in the Mid-west and west coast — where the greatest wind forces are located — Kansas, Oklahoma, for example, and California — and find what degree programs they are founding and that are underway.

well the wind energy that a single turbine can change into electrical energy really depends on the internal workings

and i dont know of any direct conversion for kinetic energy into "wind energy" sorry

To power their homes and such. How do they use energy in the night or when there is no wind? Do they have something that stores the energy like a big battery or something?

I have to “make” a green city and it will use renewable energy source including solar and wind energy. How would I make the wind and solar energy sustainable and not have shortages of power?

Small places, like a remote house or an island, might have batteries. A large place, like a city, would be connected to a "Grid", or electrical energy transmission system. If the wind stopped blowing, deep in the night, they would pull energy off the grid, from a nuclear plant, or coal-burning generation station, or hydroelectric project many miles away. A town on an island might have a large diesel generator.

I came accross a new, proven and tested home made wind power system and solar power system which eliminates our electricity bills. It was written by a Renewable energy enthusiasts Michael Harvey the diy called Earth4energy. You can get your copy to save energy and help environment while eliminating your power bills.
