- What Is Wind Energy? Wind is simply air in motion. Winds are created by the sun's uneven heating of the atmosphere in combination with the irregular surface of the earth and the earth's rotation. These winds can be harvested using wind turbines and used to make electricity. The force of the wind makes the wind turbine blades spin, and the energy of this motion is converted into electricity by a generator. See a brief wind turbine animation on DOE's Energy Basics Web site. Wind energy is a free, renewable resource. Its use does not affect its future supply. How Can We Use Energy from the Wind? Wind turbines can convert the energy in the wind into mechanical power that can be used for a variety of activities like pumping water. Wind turbines can also use generators to convert wind energy into electricity.

Wind Energy Wind turbines can be used as stand-alone applications, or they can be connected to a utility power grid or even combined with a photovoltaic (solar cell) system. For utility-scale sources of wind energy, a large number of wind turbines are usually built close together to form awind plant. Several electricity providers today use wind plants to supply power to their customers. Stand-alone wind turbines are typically used for water pumping or communications. However, homeowners, farmers, and ranchers in windy areas can also use wind turbines as a way to cut their electric bills.

- Definitions. Wind energy is kinetic energy of wind exploited for electricity generation in wind turbines. Wind energy, like other power technologies based on renewable resources, is widely available throughout the world and can contribute to reduced energy import dependence. As it entails no fuel price risk or constraints, it also improves security of supply.

- Chapter 16: Wind Energy. Wind can be used to do work. The kinetic energy of the wind can be changed into other forms of energy, either mechanical energy or electrical energy. When a boat lifts a sail, it is using wind energy to push it through the water. This is one form of work.

- Credit: Warren Gretz. We have been harnessing the wind's energy for hundreds of years. From old Holland to farms in the United States, windmills have been used for pumping water or grinding grain. Today, the windmill's modern equivalent-a wind turbine-can use the wind's energy to generate electricity. Wind turbines, like windmills, are mounted on a tower to capture the most energy. At 100 feet (30 meters) or more aboveground, they can take advantage of the faster and less turbulent wind.

- Learn how long humans have been using windmills, how big wind turbines can be, how much of the world’s electricity is generated from wind power and much more. Wind power involves turning energy from the wind into other forms of useful energy. Wind power can be harnessed in a number of different ways.For example, windmills create mechanical energy, sails move boats and wind turbines generate electricity.Windmills have been around for a long time, they were used in Persia (Iran) as far back as 200 B.C. Wind energy is clean and renewable.Large groups of wind turbines are called wind farms. Around 80 different countries use wind power to generate electricity commercially (as of 2009). In 1997 wind power generated only 0.1% of the world’s electricity, this increased to 1.5% in 2008 and 2.5% in 2010.ind energy is clean and renewable.

Wind Today, wind power provides 1.8 percent of all the energy consumed in the United States. Though wind power has increased substantially since 1970, it constitutes only a small fraction of U.S. electricity supply. In 2013, wind power accounted for 4.4 percent of all electricity generated in the U.S. Wind power can be viable for companies in areas where prevailing conditions are favorable, especially if the government compels the production of renewable energy.

Wind energy One wind turbine can be sufficient to generate energy for a household. Because wind is a source of energy which is non-polluting and renewable, wind turbines create power without using fossil fuels, without producing greenhouse gases or radioactive or toxic waste. Wind power reduces global warming.

What Is Wind Energy Used For? The blades are connected to a rotor that is connected to a main shaft. When the wind blows, the blades turn all the connected items, producing electricity via the generator. Wind energy is delivered to the power grid just like coal, nuclear or solar energy and can be used wherever electricity is used. Because wind is generated due to uneven heating in the earth’s atmosphere, wind energy can be considered a form of solar energy.

- Wind 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.

Wind power Wind power is extracted from air flow using wind turbines or sails to produce mechanical or electrical power. Windmills are used for their mechanical power, windpumps for water pumping, and sails to propel ships.ind power is very consistent from year to year but has significant variation over shorter time scales. It is therefore used in conjunction with other electric power sources to give a reliable supply.

How Do Wind Turbines Work? The terms  wind energy  or  wind power  describe the process by which the wind is used to generate mechanical power or electricity. Wind 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.ind is a form of solar energy. Winds are caused by the uneven heating of the atmosphere by the sun, the irregularities of the earth's surface, and rotation of the earth. Wind flow patterns are modified by the earth's terrain, bodies of water, and vegetative cover.
