The Wind Resource Atlas of the United States will give you a rough idea if you are in a locations with wind potential -- here is how to use it.
Basic information on wind energy and wind power technology, resources, and issues of concern. Wind Energy and Wind Power Wind is a form of solar energy. This wind flow, or motion energy, when "harvested" by modern wind turbines, can be used to generate electricity.
How Wind Power Is Generated 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.
Wind Turbines Wind turbines, like aircraft propeller blades, turn in the moving air and power an electric generator that supplies an electric current. Simply stated, a wind turbine is the opposite of a fan.
Instead of using electricity to make wind, like a fan, wind turbines use wind to make electricity. The wind turns the blades, which spin a shaft, which connects to a generator and makes electricity.
Wind Turbine Types Modern wind turbines fall into two basic groups; the horizontal-axis variety, like the traditional farm windmills used for pumping water, and the vertical-axis design, like the Power of wind Darrieus model, named after its French inventor.

Wind Power Inc. is a dormant company and its principals are retired. If you need to make contact, please use the following information: Dale Johnson. Wind Power Animation. This aerial view of a wind turbine plant shows how a group of wind turbines can make electricity for the utility grid. The electricity is sent through transmission and distribution lines to homes, businesses, schools, and so on.
Most large modern wind turbines are horizontal-axis turbines. Turbine Components blade or rotor, which converts the energy in the wind to rotational shaft energy; a drive train, usually including a gearbox and a generator; a tower that supports the rotor and drive train; and other equipment, including controls, electrical cables, ground support equipment, and interconnection equipment.

Electricity from these turbines is fed into a utility grid and distributed to customers, just as with conventional power plants. See Wind Energy Photos page for wind farm photographs.
Wind Turbine Size and Power Ratings Wind turbines are available in a variety of sizes, and therefore power ratings. The largest machine has blades that span more than the length of a football field, stands 20 building stories high, and produces enough electricity to power 1, homes.
A small home-sized wind machine has rotors between 8 and 25 feet in diameter and stands upwards of 30 feet and can supply the power needs of an all-electric home or small business. Utility-scale turbines range in size from 50 to kilowatts. Single small turbines, below 50 kilowatts, are used for homes, telecommunications dishes, or water pumping.

Wind resources are characterized by wind-power density classes, ranging from class 1 the lowest to class 7 the highest. Good wind resources e. Wind speed is a critical feature of wind resources, because the energy in wind is proportional to the cube of the wind speed.
In other words, a stronger wind means a lot more power. Advantages and Disadvantages of Wind-Generated Electricity A Renewable Non-Polluting Resource Wind energy is a free, renewable resource, so no matter how much is used today, there will still be the same supply in the future.
Wind energy is also a source of clean, non-polluting, electricity.
Unlike conventional power plants, wind plants emit no air pollutants or greenhouse gases. According to the U. It would take a forest of 90 million to million trees to provide the same air quality. Cost Issues Even though the cost of wind power has decreased dramatically in the past 10 years, the technology requires a higher initial investment than fossil-fueled generators.
If wind generating systems are compared with fossil-fueled systems on a "life-cycle" cost basis counting fuel and operating expenses for the life of the generatorhowever, wind costs are much more competitive with other generating technologies because there is no fuel to purchase and minimal operating expenses.
Most of these problems have been resolved or greatly reduced through technological development or by properly siting wind plants. Supply and Transport Issues The major challenge to using wind as a source of power is that it is intermittent and does not always blow when electricity is needed.
Wind cannot be stored although wind-generated electricity can be stored, if batteries are usedand not all winds can be harnessed to meet the timing of electricity demands.
Further, good wind sites are often located in remote locations far from areas of electric power demand such as cities. Finally, wind resource development may compete with other uses for the land, and those alternative uses may be more highly valued than electricity generation.Online shopping for Patio, Lawn & Garden from a great selection of Solar Panels, Energy Controllers, Solar & Wind Power Parts & Accessories, Solar & Wind Power Inverters & more at everyday low prices.
