Wind Energy; How Wind Turbines Work

Updated on February 23, 2012

Many governments around the world have recognized the need to subsidize their energy needs with renewable energy like wind farms. Wind farms are versatile because they can be placed on land or offshore. Wind farms have been built on shore for several decades. The worlds first wind farm was built on the side of Crochet Mountain in southern NH in December 1980. It consisted of 20 wind turbines rated at 30 kilowatts each. The United States also has the largest onshore wind farm in the world The Roscoe wind farm is located in Texas and was completed in 2008. It has a capacity of 781.5 megawatts of power. Horse Hollow Wind Farm also located in Texas has a capacity of producing 735 Megawatts of electricity.

As of September 2011 there is approximately 43,635 megawatts of wind energy being produced in the United States. Here is a map by state showing wind generation assets.

There are several prime locations in the United States for wind farms. These areas have a consistent wind supply and appropriate terrain. Onshore farms are beneficial to the landowners as tax benefits as well job creators, and a great source of income. Although most of the shoreline in the US in not suitable for offshore wind farms. The west coast has steep drop offs and deep canyons. The east coast has several locations with suitable underwater terrain. There are currently no operational offshore wind farms in the US. There are two that are proposed and approved wind farms one off the coast of Nantucket, which will produce 454 megawatts of power, and the other offshore wind farm in Delaware, which will produce approximately 200 megawatts. These will be the first offshore wind farms in the United States

New technology has made the harnessing of wind power, capable of producing more electricity than ever before. Wind generated electricity is only one part of the solution to our growing energy needs. More frequently are residential homes; businesses and schools have turned to small wind turbines to subsidize energy from the grid. Learn how to build your own wind turbine

There are several types of wind turbines. There are the typical multiple blade horizontal axis turbines. Vertical blade turbines come in many styles. I have even seen homemade vertical turbine made from old 55-gallon drums. Newer designs are emerging all the time. Turbines with multiple shafts stemming from one base, limit over all ground disturbances while maximizing wind-harnessing power. Even floating turbine, which are portable and can be used where ground conditions will not allow traditional turbines. Watch This Video To See How Wind Turbines work
