Wind power and future of renewable energy

Abstract:
Due to the development of technology around the world, the need of energy is increasing every year. But, what would be the best way to produce energy without polluting the air, or depleting fossil fuels? Renewable energy would also be the best solution for this problem. Of the available sources of renewable energy, wind power shows much promise. Wind turbines have been used through many generations, and the technology continues to develop. Wind Energy provides a feasible energy alternative to traditional fossil fuels.
Introduction:
The need for alternative energy is a pressing issue for countries all over the world. One of the solutions this for problem is wind power, which has been

This is because they can generate electricity in low wind speed. On the other hand, “vertical axes are suited well to the turbulent wind found in urban areas, and they
don’t make a lot of noise while turning. But they require high wind speed wind to start rotation.”(Scottish executive, 2007)

As we can see, many countries have used wind power to generate electricity, and the results that they have are very good. “By 2001, wind turbines around the globe were generating 30 terawatt-hours (TWh) of electricity. About one-fifth of that was being produced in North America. By 2002, worldwide wind generating capacity was expected to exceed 25,000 MW. The European Wind Energy Association hopes to install 40,000 MW by the year 2010, which would be enough
to supply electricity to about 50 million people.” (Wind Power in View, 2002). The United States has installed more new wind energy capacity than any other country in the world in 2005. (Wind energy – 2005)
Advantages and Disadvantages
Even though wind power has been used for a long time, it is not 100% efficient. The technology generates much noise while the turbines rotate, which may affect your television signal. Wind Power has both advantages and disadvantages. First, the wind is made because heat from the sun to our atmosphere is uneven; so, some paths become warmer than others. These warm patches of air rise and create wind. (Wind power- energy from the air). Wind is
