Wind with its power can produce enough energy to light up a city, provide energy for a factory, and even fly a kite. With something so remarkable as wind power, it is also a marker of the seasons changing. Actually, wind is the forces of air that flows along waters. According to the U.S. Energy Information, wind is just simply air in motion.
Wind is created upon how fast land and water on Earth are heated. As land is heated much faster than water, the cooler air interacts with warmer air, creating wind. But why is wind such an important renewable energy source?
Wind has been a renewal energy resource for centuries. Wind was used by early Egyptians to carry them overseas and windmills were created to pump water and used to produce food. By the 1920s, windmills were common manufacturers of electricity. But within a decade, power lines and the consumption of fossil fuel replaced them as energy sources. However, nowadays, with concerns of lack of fossil fuel and its detrimental effect on the environment, there are more and more wind farms or wind plants throughout the world.
The top wind farms in the world are:
1. Roscoe Wind Farm located in Roscoe, Texas in the United States, produces 781.5 MW (MegaWatts). This wind farm began as a project in 2007. It provides enough energy for 60,000 homes. It is estimated that by 2015, Roscoe Wind Farms will provide over 5,000 MW in new renewal energy for Texas. This powerhouse has led to future projects close to Abilene, Texas and to the Champion project, a 126 MW wind farm.
2. Horse Hollow Wind Energy Center located in Texas, produces 735.5 MW. It covers almost 47,000 acres of land in the counties of Taylor and Nolan in northwest Texas.
3. Walney Wind Farm located in the United Kingdom, produces 367 MW. It is located 15 km (approximately 9 miles) offshore of Walney Island, Cumbria of the United Kingdom shoreline. It consists of 2 Walney Wind Farms. Walney 2 began operation on November 2011. And Walney 1 recently started operation in February 2012. It produces enough energy to supply 320,000 homes.
4. Thanet Offshore Wind Project located 12 km (approximately 7 miles) from the Foreness Point on the eastern side of Kent in the United Kingdom produces 300 MW. It supplies enough energy for 200,000 homes. It is one of the largest offshore wind farms in the world housing 100 turbines that covers an area of 35 square km (13 square miles).
5. Gansu Wind Farm located in western region of China is proposed to harness 20,000 MW by 2020. This wind farm project began in 2008. By 2010, it produced more than 5,000 MW. This project is also referred to as the Jiuquan Wind Power Base.
Renewable energy sources are among us everyday. With the signal of climate change, wind provides the type of renewable energy that can be seen throughout the world. This type of clean energy source is harnessed in wind farms.
