Wind generators are devices that convert wind into electrical power. Also known as wind turbines, these generators are electrical. Windmills were the first device to convert wind into wind electrical power. Those wind mills had engines to generate power for applications such as grinding, hammering, pumping, and other different tasks involved in farming.
Today, there are still windmills erected in various farms as the source of their energy especially because the principal source of energy is thousands of miles away from these rural areas. In countries such as Denmark, Spain, Germany, India, and some areas of the United States of America, wind energy is the primary source of electricity.
With global warming and pollution taking their toll on nature, wind generators are considered to be among the huge forms of green energy widely used today. They are practical and advantageous in regions where the wind’s velocity reaches 10mph.
The benefits of wind power are many and the wind being free is the greatest of them all. It is also sufficient and renewable. Those who rely on it believe that wind power is cheap, reduces emission of toxic gases, and is widely distributed.
Over the last decades, the cost of wind energy production has been reduced dramatically by 80%. It can also minimize the greenhouse effect, does not generate pollution, and is more permanent. It is as permanent as the sun, the moon, and the stars. Scientists assert that if all wind power is harnessed together, the energy available will be 10 times more.
As mankind faces the energy crises, wind generators or wind turbines may prove to be among the ultimate solution as the wind is omnipresent. Every country does not have to depend to another to produce electricity from the wind. This is the reason why rural areas or the remotest places on earth can be powered electrically.
Once the wind turbine is constructed, the energy it generates is devoid of greenhouse gases and other pollutants. These turbines are tall. Yet, they actually take up a portion of the land and leave the land below the turbines to be of use for other purposes.
Depending on the sizes used, the wind turbine or turbines can power up an entire house and barn or a village or a small town.
Nevertheless, wind generators or wind turbines come with flaws too. For one thing, constructing wind turbines may actually be expensive. Despite being low in costs in converting winds into energy, a huge quantity of turbines are required to generate electricity enough to power up a decent house.
For another thing, though wind energy does not contribute to air pollution, it produces noise which can be considered to be a form of pollution or contribute to noise pollution.
Another drawback of wind generators is its inconsistency. While it is permanent, it is unpredictable. In areas where a large amount of electricity is needed, a long line of turbines is required to produce the proper amount of electric energy.
Wind generators or wind turbines are beneficial. However, to maximize their advantage, a vast knowledge is needed to ensure that the wind can adequately supply energy.
