Skill OneWind turbines convert the kinetic energy in the wind into mechanical power. This mechanical power can be used for specific tasks (such as grinding grain or pumping water) or a generator can convert this mechanical power into electricity to power homes, businesses, schools, and the like.

Skill TwoWind power captures the natural wind in our atmosphere and converts it into mechanical energy then electricity. People started using wind power centuries ago with windmills, which pumped water, ground grain, and did other work. Today's wind turbine is a highly evolved version of a windmill. Modern wind turbines harness wind's kinetic energy and convert it into electricity.

Skill ThreeWhen wind blows past a turbine, the blades capture the energy and rotate. This rotation triggers an internal shaft to spin, which is connected to a gearbox increasing the speed of rotation, which is connect to a generator that ultimately produces electricity. Most commonly, wind turbines consist of a steel tubular tower, up to 325 feet, which supports both a "hub" securing wind turbine blades and the "nacelle" which houses the turbine's shaft, gearbox, generator and controls.

The current estimate of wind energy potential is 10 times the amount of electricity consumption for the entire country. This strong wind resource varies across the country by region and topography. Wind energy projects are developed by companies that seek out the areas with the strongest wind resource but also review other critical factors like access to land, access to the transmission lines, ability to sell the electricity, and public engagement other significant development factors. Once a site is identified, a developer will conduct wind resource assessment, siting and permitting, transmission studies over a period of several years..

Wind energy is a clean, renewable form of energy that uses virtually no water and pumps billions of dollars into our economy every year. Since 2008, the U.S. wind industry has generated more than $100 billion in private investment. Furthermore, wind energy is a drought-resistant cash crop in many parts of the country, providing economic investment to rural communities through lease payments to landowners. Wind energy helps avoid a variety of environmental impacts due to its low impact emitting zero greenhouse gas emissions or conventional pollutants and consuming virtually no water.
