Renewable forms of energy are those that replenish themselves
naturally and at a faster pace then they are used. One, almost perfect,
example of renewable energy is wind.
Wind is the natural motion of air. It occurs whether we are around or not. In that sense, it is a natural form of energy. Specifically it happens because cold air replaces warm air. As warmer air near the ground is heated it rises to be replaced by the cooler air above.
The challenge in using this type of energy is figuring out a way to capture it. There are probably dozens of ways that this can be accomplished, but the prevailing method of capturing wind energy today is to convert it into electricity and store it.
Typically, the method used to capture energy from the this type of energy are wind turbines. Briefly summarized, a wind turbine generates electricity from moving air. It captures energy from the wind using blades that are easily turned by the wind. It then transfers that energy to a generator shaft. Such a turbine is similar in concept to a wind mill. The difference is that energy from a wind turbine is stored. Energy from a wind mill is used directly to crush grains or pump water. In other words, energy from a wind mill is used directly.
The popularity of wind energy is being highlighted by the number of municipalities that are helping to offset the initial costs of installing wind turbines or wind mills through tax credits. Wind power plants, i.e. cluster of wind machines are also often partially supplemented by the government.
This type of energy is not a perfect form of renewable energy, however. If the wind is not blowing, no energy is being created. Therefore, wind energy is not a form of energy that can be used without having some sort of a backup source of energy.
In a way, wind energy is an indirect form of solar energy. That is because without the sun heating the surfaces of the air, we would not have wind.
Is wind energy enough to help us to rid ourselves of our over reliance on non-renewable forms of energy like coal and oil? At present, this is unlikely as only a little over one percent of all the energy generated in the U.S. comes from the wind. But even though it is a small amount of energy when contrasted to the amounts of energy required to power the entire county, it is enough to partially power mechanical machines and appliances used in many farm areas.
