Wind turbines can be built on existing farms or ranches. This greatly benefits the economy in rural areas, where most of the best wind sites are found. Farmers and ranchers can continue to work the land because the wind turbines use only a fraction of the land.
What is Wind Farm?
A wind farm or wind park also called a wind power station or wind power plant is a group of wind turbines in the same location used to produce electricity. Wind farms vary in size from a small number of turbines to several hundred wind turbines covering an extensive area. Wind farms can be either onshore or offshore.
Types of Wind Farm
Offshore wind energy or offshore wind energy is the use of wind farms that are built in bodies of water, usually in the ocean, to generate wind energy to electricity generation. Compared to land, higher wind speeds are available offshore, so the electricity generation of offshore wind energy per installed capacity is higher.
How does wind energy work?
A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag.
Where can wind turbines be built?
Wind turbines can be built on land or offshore in large bodies of water like oceans and lakes. The U.S. Department of Energy is currently funding projects to facilitate offshore wind deployment in U.S. waters.
What causes wind?
Wind is a form of solar energy caused by a combination of three concurrent events: 1 The sun unevenly heating the atmosphere 2 Irregularities of the earth's surface 3 The rotation of the earth.

How do wind turbines work?
Winds are caused by the heating of the atmosphere by the sun, the rotation of the Earth, and the Earth's surface irregularities. For as long as the sun shines and the wind blows, the energy produced can be harnessed to send power across the grid. Wind turbines can be built on existing farms or ranches.
Why is wind energy important?
Because the electricity from wind farms is sold at a fixed price over a long period of time (e.g. 20+ years) and its fuel is free, wind energy mitigates the price uncertainty that fuel costs add to traditional sources of energy.

Criticism
The environmental impact of wind farms is minor compared to that of fossil-fueled power plants. Wind power consumes no fuel, and emits no air pollution, unlike fossil fuel power sources. The energy consumed to manufacture and transport the materials used to build a wind power plant is equal to the new energy produced by the plant within a few months.
