Most people figure that there will always be some more wind coming along later, so they call it renewable.
It will never be depleated. ex. fossil fuels are non renewable because eventually they will run out. Wind will always be around for our use.
Wind Energy

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. Turbines catch the wind's energy with their propeller-like blades. Usually, two or three blades are mounted on a shaft to form a rotor.
A blade acts much like an airplane wing. When the wind blows, a pocket of low-pressure air forms on the downwind side of the blade. The low-pressure air pocket then pulls the blade toward it, causing the rotor to turn. This is called lift. The force of the lift is actually much stronger than the wind's force against the front side of the blade, which is called drag. The combination of lift and drag causes the rotor to spin like a propeller, and the turning shaft spins a generator to make electricity.
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.
Small wind systems also have potential as distributed energy resources. Distributed energy resources refer to a variety of small, modular power-generating technologies that can be combined to improve the operation of the electricity delivery system.
No
Wind energy is used like regular coal energy with a slight difference as wind energy is renewable.
Wind is renewable. Wind energy is renewable because it harnesses the earth's natural winds. Wind power does not consume anything to be produced. It is the same basic concept as hydroelectric power.
The wind turbine manufacturer is the primary consumer of the wind energy. One advantage of the wind energy is clean and renewable.
it is a renewable resource
No
Wind energy is renewable energy.
No, wind is a renewable energy source. The wind will always be blowing!
Renewable
Wind energy is renewable energy.
Yes, a wind turbine is a renewable energy source!!
It is renewable because, wind will never go away. Wind energy is renewable, so solar. Fossil fuels are non renewable. It is important to use wind or solar energy because it is renewable.
Wind is a renewable resource on earth. Wind turbines can be used to catch the wind's energy and be used to create electricity.
yes because wind is a renewable source of energy
The most popular renewable energy sources currently are: Solar energy. Wind energy. Hydro energy. Tidal energy. Geothermal energy. Biomass energy.
Wind turbines produce renewable energy. Energy is considered renewable when it is created by a source that is inexhaustible.
yes wind is a renewable source of energy and that is what turbines use
