A windmill produced electricity while the wind blows. It may produce energy when the wind blows and people don't need it. People don't need all the energy a windmill produces all the time but they may need energy when the wind is not blowing. Windmills are therefore linked up to battery systems and charge the batteries when the wind is blowing, energy is being produced, and nobody is using it.
When people need energy and the wind is not blowing (no power is being produced) they use power from the batteries.
What else can I help you with?
Where are windmills being used today?
I am doing giant windmills in class today and I just wondered if you could answer my question for me? This is my question: 'are giant windmills used anywhere already' thankyou!!!!!! As far as I know the biggest in use now is rated at 2 megawatts
Do wind mills still work if there is no wind?
No, windmills rely on wind to generate power through their blades rotating. If there is no wind, the windmill will not be able to produce electricity.
What do you store energy from windmills in?
Old windmills wouldn't particularly store energy. For example they would only grind grain when the wind was blowing. Or they would pump water into a tank when the wind was blowing. Modern windmills generally generate electricity. For commercial windmills they are attached to the "Grid" which they treat somewhat as a battery. There still is risk of uneven power generation which would need to be evened out with either a storage method (some have suggested using battery powered automobiles as a "battery bank", or used with a complementary generation system that could be easily varied. For example hydro-electric may allow some diurnal variation in generation. It could still be a problem if there were many days of very high or very little wind. Off grid systems are usually connected to some kind of a charge controller and then dumped into a battery bank. There is a risk of overcharging the batteries, and it is suggested to have some kind of a "dump load" such as an electric heater that can waste excess electricity without disconnecting the windmill from a "load device".
When electricity sis not moving but stored it is called?
Stored electricity? It's a form of potential energy I guess but it's still called electricity
Is the kite still being used today?
Yes definitely ! Other common uses of windmills: - Water pumping (to dry fields or to water crops) - Energy production (either mecanical or electrical through an alternator)
What type of electricity is not useful?
The LEAST useful form of energy is Static Electricity however it to still find some uses.
Who can cars run on windmills?
When cars are stronger the mini windmills can generate some power when still and alot when moving. Hope this helps!
How are windmills beneficial to science?
they are renewable resources, even though they take a long time to break even, it is still a source of energy that is renewable, which means it can never run out
What is the principal source of energy?
For electricity it is still coal, at about 50 percent. For transport it is oil.
What is main source of energy that you use today?
For electricity it is still coal, for transport it is oil
What are wind mills mainly used for?
Orginally windmills were used as a source of power to turn stones to grind grain and make flour. Many can still be seen in places like The Netherlands. Wind turbines are a different mechanism and are used to collect wind power as a "green" alternative to using fossil fuels to make power.Windmills provide energy to allow things to run. They are an alternate energy source that not many use, but are very good for the environment.
What is called electricity at rest?
Electricity at rest is called static electricity, which occurs when positive and negative charges build up on objects without flowing in a current. This can lead to phenomena like sparks, lightning, and the attraction of small objects through static cling.
