The Basic Facts about Wind Energy
One of the form of solar energy is wind.t 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. This wind flow, or motion energy, when “harvested” by modern wind turbines, can be used to generate electricity.
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.Specific tasks such as grinding grain or pumping water or generator can convert this mechanical power into electricity to power homes, businesses and schools with the help of mechanical power.
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 then connects to a generator and makes electricity.
Horizontal-axis variety like the traditional farm windmills used for pumping water, and the vertical-axis design name after its French inventor are the two basic groups of modern wind turbines. Most modern wind turbines are classified as horizontal-axis turbines.
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. We all know that wind energy is a free and renewable resource that is why 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.
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. Roughly 80% of the cost is the machinery, with the balance being site preparation and installation. 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 generator, however, wind costs are much more competitive with other generating technologies because there is no fuel to purchase and minimal operating expenses.
Using our alternative resources as alternative energy can solve different issues. Utilizing this energy sources will help our environment clean and other energy consumptions we are experiencing nowadays.
