Wind turbines are emerging as one of the easiest ways to create renewable energy. Wind turbines are fairly easy to build and erect, and unlike power plants, wind turbines can be put up a few at a time. If you need fifty of them, you don’t have to put all of them up at once. This makes them easier to afford, and also allows them to start working sooner. As soon as one is up and connected to the system, it can start generating electricity.

There are a couple styles of wind turbines. The most common are the tower style that have what looks like a windmill on the top. A great thing about this style is that they are made in almost any size. They may be huge, to create a lot of electricity to be fed into a city grid, or small to power a home of workshop. The other style may look like a water paddle or eggbeater set on its side. Small versions of these are sometimes found on top of people’s barns or other buildings.

The method of propulsion is very simple. The energy of the wind catches the blades or arms of the wind turbine, causing them to turn. The blades are shaped in a certain way to allow for them to catch even the lowest winds, but not break in high winds.

When the blades turn, they turn a rotor, which then turns a low-speed shaft. This low-speed shaft turns a gear that is connected to the gear of a high-speed shaft. This shaft runs through a generator housing.

In the generator housing is a magnetic rotor that is attached to the high-speed shaft. This rotor spins in a core made of iron that has copper wire coiled around it. The spinning rotor creates “electromagnetic induction” inside this core, which makes an electrical current. Once this current is flowing, it can be regulated and fed into a grid or electrical system of a house.

Another use for wind turbines is as a backup energy system. For instance, you can have a small wind turbine that charges up a battery backup system that you can use if the power goes out at your house. The turbine will keep these batteries charged and ready for use. A regulator on a system like this will prevent the batteries from overcharging.

The main drawback to wind turbines as a source of energy is that they are only effective in places where there is steady wind. But once they are in a good place, wind turbines create a lot of clean energy. Another great thing about these turbines is that they can be put in places that are no good for habitation or farming, so they aren’t taking up land that is needed for other things. Every year more prime places are found to put them.

Wind turbines are a very realistic prospect for renewable energy in the near future. Some countries are already using wind power as a source for up to 10% of all their electricity. With some more research and refinement of wind turbines, we may soon be seeing ‘wind farms’ all across the country, powering our homes with clean electricity.
