WHAT IS ENERGY WHEN USED WITH WIND POWER?
WINDMILL FARMS ANSWERS:
Wind turbines convert mechanical energy (wind moving over the blades) into electrical energy (current & voltage out of the electric generator).
The big turbines are AC, and do not store the energy. They put it directly onto the grid.
(There are a few experimental systems where very large batteries are used to smooth, store, or otherwise regulate the power put onto the grid, but these are not strictly part of the wind turbine.)

WIND ENERGY?
i know WINDENERGY is powered by a generator, but how does this help? doesnt the generator use oil or gas? this wouldn't help reduce costs would it?
WINDMILL FARMS ANSWERS:
Hello my husband works on the commercial wind turbines. You got two correct answers from the other two posters, but I'll try to put it into simpler terms.
First off my husbands wind turbine site has 43 turbines. In a year they produce about two 55 gallon barrels of waste oil/grease a year, for all 43.
Yes, turbines use oil/grease. If the oil or grease must be changed out (like a part got chewed up, and the oil is now contaminated) then it goes off to be recycled. It is never just dumped in landfills. It is always recycled. So in effect wind turbines produce no waste oilit always has a second "life."
Wind turbines take a lot of energy to manufacture, but over the course of their life, they generate much more energy than was used to manufacture them.
Did you ever play with a pinwheel as a child? The colorful things that spin on the end of a stick?
Imagine the pinwheel is connected to a tiny generator. The wind causes the pinwheel to spin, and that turns the generator, and makes it generate electricity.
Wind turbines of course do so on a large scale.
Yes they reduce costs, and provide a very clean source of energy.

Thomas asks...
IN WHICH INDUSTRY WE USE WIND ENERGY?
WINDENERGY can be used for power generation I know also that WINDENERGY in farming,WIND pumps,
WINDENERGY is a pollution-free, infinitely sustainable form OFENERGY.
thanks
WINDMILL FARMS ANSWERS:
Any industry can use electricity from wind generators
George asks...
WHAT OTHER SOLUTIONS ARE THERE NOT TO USE WIND TURBINES/WIND ENERGY?
I am trying to find solutions on what people can do not use WIND turbines because it has so many disadvantage OF having it. I need solutions what can people do so we wont use them anymore.
WINDMILL FARMS ANSWERS:
If you are in the UK this is the answer due to Government subsidy.
We have installed solar panels that we own so know how the system works.
"Free" ones are just that. The house owner gets the "free" use of electricity generated so you can save on your electric bill.
However to fully benefit you have to be careful when you use electricity. For example if you use a washing machine / dishwasher / tumble dryer at night when the panels aren't generating you don't/can't get free electricity! During a sunny day the panels might be generating 1kw but if you switch on a 2kw appliance you pay for the excess1kw needed to run the appliance.
So yes you will save some money on your electric bill but probably only 40% certainly not 100% of your bill.
The owner of the panels (i.e us!) is the one to benefit. We have a 4kWh system (biggest allowed under Government subsidy) and get paid +/-46p per kilowatt hour generated. We all buy electricity from the Power Companies at 12-14p unit so it is a huge subsidy - which the rest of you are paying - not the Government - one reason why bills are so expensive now!
As a generalisation the capital cost was lb12,000 but I am earning +/- lb1600 year. To put another way although I still buy some electricity and all gas in effect we will be getting all our gas / electric "for free" and about lb600 extra cash in hand!
If you have the cash BUY YOUR OWN as the scheme is Government guaranteed for 25 years!
In investment terms it is a 8-12% TAX FREE return for 25 years - you can't get anything like that anywhere else.
If you want more specific help email me and I can do the figures for your house and send some pictures of our installation.
P.S. Even on dull days it still generates. Recently on a rainy grey overcast day we were still generating about 240w. So in Janaury when it will be freezing with perhaps snow on the ground as long as the sun is shining we will be generating! It converts light to power - heat is not needed to make it work!
Donna asks...
WHAT ARE THE ENERGY CONVERSIONS THAT OCCUR IN CREATING ENERGY USING WIND?
In point form, how is ENERGY generated from WIND and what ENERGY conversion occur?
WINDMILL FARMS ANSWERS:
Wind energy is kinetic energy, the kinetic energy of the wind is converted into mechanical energy (still kinetic really) which is converted into electrical energy by the rotation of conductors in a magnetic field or the rotation of a magnetic field around conductors.
The wind energy itself is created from heat energy, which is created from electromagnetic (light) energy from the Sun which is created by nuclear energy from the fusion of hydrogen.
