No. Windmills use the wind for various puposes such as grinding grain, pumping water, and generating electricity.
it isn't always the same, but genorally four. the wind turbines used for generating electricity however, usually have three
Soo there is a turbine in the center of the rotating part, so when the wind make the three spikes rotate, the turbine spins generating electricity. It makes electricity; it doesnt need it. The turbine king of works like a rotor or if you know anything about hyropower elctricity then you know about the turbine that spins when water falls. So basically in windmills, the wind causes the spikes to turn making the turbine work generating power... hope it helps...:)
Wind power is renewable cheap and available world wide
Well wind energy is all the same , it is energy that comes form the sun (which heats the air and this causes winds). The energy can be harvested by sails (as in sailing ships) or by wind mills (as in grinding flour or pumping water) or wind turbines (as in generating electricity).
wind turbines have blades like the propellors on the first aeroplanes wind turbines with blades convert 20-30% of wind energy into electricity but this new turbine can convert 70%.
a wind field
wind farms are built and turbines are put up. As the wind blows it turns the turbines generating electricity.
They're connected by cables. The wind spins the turbine - generating electricity. The electricity is fed into the national grid by cables.
Pumping water, and generating electricity. Sailing boats.
No. Windmills use the wind for various puposes such as grinding grain, pumping water, and generating electricity.
A windmill is a machine that is powered by the energy of the wind. It is designed to convert the energy of the wind into more useful forms using rotating blades or sails.windmills served originally to grind grain, though later applications included pumping water and, more recently, generation of electricity. Recent electricity-generating versions are referred to as wind turbines.They are used for generating electricity.
Wind mills were; and still; useful for grinding some crops, lifting up water for irrigation and agriculture, and generating electricity.
Wind propels wind generator which convert the moving energy to electricity. I don't know . can u please help me
There are several ways to generate electricity. Solar, wind, coal, nuclear, diesel etc.
To produce or make electricity is to generate it. Some of the common ways of generating electricity include using wind power, geothermal energy and burning fossil fuels among others.
