Wind Energy Basics
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. 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.
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, 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 eggbeater-style Darrius model, named after its French inventor. Most large modern wind turbines are horizontal-axis turbines.
Utility-scale turbines range in size from 100 kilowatts to as large as several megawatts. Larger turbines are grouped together into wind farms, which provide bulk power to the electrical grid.
Single small turbines, below 100 kilowatts, are used for homes, telecommunications dishes, or water pumping. Small turbines are sometimes used in connection with diesel generators, batteries, and photovoltaic systems. These systems are called hybrid wind systems and are typically used in remote, off-grid locations, where a connection to the utility grid is not available.
SABA Instruments Co., is your One Stop Shop for reliable residential or business wind turbines, off grid and grid tie wind generators, wind generator rotor blades, wind turbine components, and wind turbine accessories, wind turbine inverters. We can offer wind generators which are the perfect choice for energy efficient residential home and business.
A small home wind turbine is a long term investment. Before you purchase a wind turbine, the first factor to consider is if the energy produced by a wind turbine can pay for itself in 10 years or less. In order to achieve this, the wind turbine must be a high quality, reliable, maintenance free wind turbine with excellent performance.
The second factor to consider is installation and ownership cost. Poor reliability, low quality and high maintenance will greatly increase ownership cost and make the wind turbine impossible to pay for itself.
The third factor is environment and safety. A small home wind turbine should be safe for high winds, quiet and have no vibrations to make it residential/home friendly.
