A wind farm is a group of wind turbines in the same location used for production of electricity . A wind farm may be located on onshore/ offshore. Many of the largest operational onshore wind farms are located in the USA and China. The world's first wind farm – consisting of 20 wind turbines rated at 30 kilowatts each – was installed on Crotched Mountain in southern New Hampshire in US in December, 1980 .Europe is the leader in offshore wind energy with the first offshore wind farm being installed in Denmark in 1991.
Offshore wind farms:
Offshore wind farms refers to the construction of wind farms in bodies of water to generate electricity from wind. Better wind speeds are available offshore compared to on land.
Offshore turbines require different types of bases for stability, according to the depth of water. No Noise Pollution . No Injuries to Birds , No loss in scenery . Higher costs as a main challenge.
Onshore wind farms:
Onshore wind farms refers to the construction of wind farms on land. They are most affordable renewable energy resources, Low Cost which is around half the cost of offshore wind and a quarter of the costs of solar photovoltaic panels.
Onshore wind farms operate on land, generally in places of high altitudes or in large open spaces where the wind tends to be strongest. In the United States, the states with the greatest onshore wind capacity include North Dakota, Texas, Kansas, South Dakota, Montana and Nebraska. Onshore wind farms offer several key advantages over offshore farms. The turbines, for instance, are much easier and less expensive to set up, maintain and operate than offshore turbines. Onshore farms also have easier and less costly access to the utility grid. Drawbacks, on the other hand, include weaker yet more turbulent winds than those offshore. Onshore projects also often face opposition from area residents due to aesthetic disruption of landscape as well as the noise pollution issues.

2 .Choose an appropriate location. Check the average wind speed in your proposed area by referring to wind resource maps and information on wind speeds by zip code that are available on most state energy department websites. For wind farms, an annual average wind speed of 11 miles per hour or more is required to power the turbines. Besides wind speed, consider other factors such as access to power lines and environmental or community impact.
3.Research local laws and obtain necessary permits. Each state may have its own rules and zoning laws, so it's best to check with local officials about obtaining a permit to start a wind farm. Though many states and federal governments provide incentives for developing wind farms in the form of tax credits, at times there are restrictions on building wind farms due to air traffic safety, noise, aesthetics and property values.
4 .Buy wind turbines for your farm from a certified energy company. Once you have the necessary permits, purchase wind turbines based on your budget and the type of wind farm you want to start. Again, state laws may govern the type, height, number and quality of wind turbines so this must be considered before purchasing them.
5 .Build power transmission lines or partner with a local company. If you have a large wind farm, then you can set up your own power lines that carry electricity from your wind farm to your customers. Small wind farms usually partner with local power distribution companies that sell the electricity through their own power grid.
