Cleaner Wind Power Electricity
The debate continues in most countries about the merits of different sources of electricity. Most countries use generators that are powered by fossil fuels like gas, coal and oil of which we have only limited resources. As a consequence many countries have been looking into alternative power sources such as solar and wind power electricity. These clean sources of electricity are becoming increasingly popular due to the fact that they are renewable sources.
Differing consumer groups often drive the sources of energy that they feel best suits their needs. However each type of energy source has both advantages and disadvantages that need to be considered as not every source of power is suitable or even available everywhere.
One of the most popular sources of clean energy is wind power electricity because generating electricity from wind has no harmful by-products. As a consequence many of those who care about the environment are campaigning for more wind turbines to produce wind power electricity for their homes. Wind power electricity has none of the drawbacks of traditional powered sources; it is green, produces no smelly gases or plumes of smoke.
To understand how wind can be turned into electricity it is important to understand how the generator works. A generator is the equipment that converts kinetic (movement) energy into electricity. There are a plenty of sites on the internet that can give you a technical understanding but here are the basics. A key component of an electric generator is the “prime mover” which is any mechanical force that rotates a certain part of the generator and in early generators this was done manually with manpower.
This was soon found to be inadequate and so other sources to act as the prime mover were needed. In the 1950s designers began to look at ways of producing generators that harnessed wind as its prime movers. By the 1970’s engineers had a wind turbine generator in operation which then paved the way for a future for wind-powered electricity.
For obvious reasons these wind power electricity generators need to be carefully located in places where there is a constant source of strong wind. The most suitable sites for these turbines tend to be in coastal locations where they benefit from both the breeze on land and sea. With careful positioning these turbines create wind power electricity that can reach from several kilowatts to megawatts which is enough electricity to power a medium-sized community.
Wind power electricity has meant that islands, and other remote locations can produce their own power without the need for expensive and impractical underwater cables from the mainland. Difficult to reach archipelagos have benefited greatly from this clean electric power generation.
There are many obvious advantages provided by wind powered electricity. It solves the problems of our dependence on diminishing fossil fuels and the requirement for environmentally friendly energy sources. Whilst it was once only used for remote communities, wind power electricity is being heralded as a viable alternative for major conurbations.
