There are several different types of wind energy. At its most basic wind is really a form of solar energy as wind is formed from the warming of the earth. Winds occur because the entire earth is not heated to the same temperature and land heats up much faster then water. These temperature differences produce wind. It is possible to gather this wind energy and turn it into various different types of power and one of the most popular engines for this today is the wind turbine.
To collect wind energy the wind is used to rotate blades on a windmill or turbine which converts this rotary motion into electricity. This electricity can be employed for many different activities including pumping water or powering your household.
A wind turbine is a tall tower with huge propeller vanes. Unlike a fan which is run by electricity the wind turbine moves due to the wind and this movement is what produces electricity. The blade turns, the shaft spins and this shaft is connected to a generator that produces electricity. The majority of wind turbines use a horizontal axis though there are vertical axis turbines that look more like egg beaters than propellers. The largest wind turbines are horizontal axis turbines.
Wind energy is desirable because it does not create any greenhouse gasses and is renewable. You can collect as much wind power as you want and there will still be enough of wind in the future. It also does not produce any greenhouse gases or air pollutants.
Whilst wind power is very cost efficient the initial costs are still very high, though you will soon make this money up by all of your energy savings. Most of the cost is purchasing the machinery. However there is not much maintenance required, no fuel and very low operating costs.
The main concerns with wind turbines are that the blades may produce a lot of noise and are not very pretty to look at. For this reason, wind farms and even residential turbines are usually placed far away from view and out of hearing distance. The blades also have killed birds and bats that have flown into the blades. Most of the newly designed wind generators have reduced problems and it is possible to disguise the wind turbine.
As long as there is even a slight breeze you can get energy from the wind. However when there is no wind you may have issues. The only way to store wind energy is to connect batteries to the wind generator or are directly hooked into the electrical grid. As this technology grows, there will be better choices for storage of the energy, making wind power accessible to more people.
