How to Generate Electricity From Wind?
If you are like many Americans, you are probably scared to receive the utility bills at the end of the month. This is normal in this uncertain economy.
Did you know that you can save more than 70% on your utility bill by switching to alternative sources of power?
If you want, you can choose to live off the grid and say goodbye to your energy bills for good. Thousands of people are already doing it, and you can to by creating their own homemade wind generators.
How can you create alternative energy and save money?
You can create alternative energy by using the power of three natural elements.
1. Sun power
2. Wind power
3. Hydro power
In this article, we are going to talk about using wind power to create electricity. To make your own energy with wind power, you are going to create your own homemade wind generators.
Before you consider building your own wind generators, make sure that there is enough wind in your area. If there is not enough wind, you will not be able to produce the amount of kinetic energy you need to convert the wind into electricity.
Once you installed your own windmill, you will not have many things to do since they don’t require a lot of maintenance. The only problems I can see would be when a bird is is made prisoner by your windmill, or a major storm in your area. In this case, your tower will probably suffer.
Be aware that installing your own home made wind generators can cost you from a few hundreds dollars to a few thousands. You need to conduct your project seriously and learn about all the option available to you before you start. If you really want to do it yourself, you may want to invest in a good guide like earth4energy manual for example. You will save a lot of money.
The benefits of installing your own windmill generator beside saving money is that you will contribute to the reduction of carbon dioxide reducing emissions.

How do you generate electricity from wind turbine?
The wind turns the turbine. When the turbine turns it was connected to a magnet. The magnet is surrounded but a metal that when the magnet moves produces electricity. The electricty is travelled to grids then into your house to power lights ect.
Hope this helps

The wind turns the blades which turn a shaft that is connected via a gearbox to an alternator. The alternator is powered up (they use a little bit of electricity) and the rotation transferred from the blades of the turbine turns the alternator which generates electricity using electromagnets and coils inside it.
The wind is not constant so a wind turbine only produces, on average, about 20% of its rated output. So, when they say on the news that a wind farm will power 100 houses, they are talking about its rated output. What is will really power is 20 houses.
Unfortunately, there is no mass storage for electricity so it has to be used or dumped. Use means connecting it to the national grid. The trouble is that the national grid needs to stay roughly constant – you don’t want your lights going bright and dim or your TV going off and on – but wind power fluctuates wildly. The solution is to have conventional CO2 emitting power station running to create spare capacity to level out the uneven supply from wind power. When the standby power is not needed, the power station is wasting energy and producing pollution. So, wind power turns out to be much less environmentally friendly than it seems.

The turbine is connected to a generator, which produces electricity. More specifically, a generator creates DC (Direct Current). This can be used to charge a battery, supply DC devices, or run through a circuit called an "inverter" to convert it to AC (Alternating Current) and used to supply typical household appliances.
In many localities, a home wind turbine owner can connect the turbine to their house mains in such a way that when the turbine is generating more power than is currently being used, it feeds out through the electric meter (in effect crediting the owner for the power they’re generating) and into the grid.
p.s. ignore most of what Thorpe has to say – batteries are a perfectly functional means of storing power from a turbine (common setup for people living off the grid); a well located turbine can produce much more than "20% rated capacity"; there are many non-CO2-generating sources of electricity; by it’s nature, the demand and supply of the "grid" is constantly dynamic, and while current technology wouldn’t allow wind-generation to replace all other power sources, it can most certainly be used as a supplemental source (and is – in the U.S. and all over the world)

Agreed, some well sited commercial wind farms operate at over 40% capacity.
Most commercial megawatt class turbines produce AC electricity, not DC. This does make storage nearly impossible for wind power to remain competitive. Some companies are working on storing excess power, or power generated at off-peak times, as compressed air stored in large natural reservoirs or abandoned gas wells.
Conventional plants are required because the wind doesn’t always blow. However, when power output from wind resources is high these plants operate in standby, and some (like natural gas fired plants, which can be quickly restarted) or other peak-load supplying stations completely shut down. There always needs to be a base load supplied by a conventional source. Obviously when running in standby they emit substantially less pollutants than when operating at full or even partial load, so wind turbines certainly are good for the environment.

Me
its an easy way for electricity generation
i’ll tell u thing u can do it home
get a small motor from any ship toy and connect a led to it then rotate the motor using ur hand and look to the led ( it’s turn on ) .
its the same as the wind turbine but using the wind to rotate a big fan that connected to a generator that generate the electricity and there is more tools that enhance the output of the generator e.g a frequency stabiliser the adjust the frequency of the output coz the wind isn’t constant all day and night and that coz vibrations in the frequency ( unwanted thing in the output ) and so on.
and we didn’t work with one turbine but with field of them in a wide place ( desert ) to get more power.
