They had an installed capacity of approximately 282, 482 MW (megawatts) by the end of year 2012. Wind energy production is about 450 TWh which accounts for 2.5% of the total global electricity usage and production. (Wikipedia, pr. 4)
Regions where wind power is widely used include United States, Asia and Europe. However, other countries that have achieved have also attained some notable high levels of wind- energy usage include Denmark (21%), Germany (9%) and Ireland (14%). Also Spain (16%) and Portugal with 18%. In the year 2011, Germany and Spain had about 50% of their electricity being sourced from solar and wind. A recent study of 2011showed that over 83 countries worldwide are using wind- power for commercial and business basis. Most of the large onshore operational wind farms are found in the United States of America (USA). London Array in the UK (United Kingdom) was declared the largest offshore wind farm all over the world producing about 630 Megawatts (MW). Its runners-up is the GGWF (Greater Gabbard Wind Farm) that produces about 504 Megawatts (MW). Gwynt y Môr wind farm is one of the largest running projects. It is under construction and is aimed to produce approximately 576 megawatts (MW). (Wikipedia Pr. 4)
Among the problems that would be encountered in wind energy includes noise pollution. This is caused by the wind turbines as they rotate. Wind turbines must be located in open areas free from interference from trees and large buildings. This enhances the rotation of the turbines. On the other hand, this will lead to deforestation as people will cut down trees to settle wind turbines (Rosenbloom Pr. 3).
The author’s primary focus was on crude oil. David argues that the prices of the commodity is always on the rise and that it also causes environment degradation. In addition, he argues that the oil levels are going down. In connection to this, he suggests that the World should turn to wind
