Residential Wind EnergyResidential wind energy is gaining a new popularity with the development of a greater variety of wind turbines. Wind power has been used for centuries. Probably the most widespread use was to harness the power of the wind to drive sailing ships. Another noteworthy application was to power windmills used to pump water, particularly in Holland. Today wind power most commonly refers to harnessing the wind by means of wind turbines and converting it to electrical energy. Wind turbines consist of two or three propeller-like blades, a rotor and a generator which are mounted on towers. As the wind turns the blades, the kinetic energy in the wind is converted into mechanical power. The generator then changes it into electricity. There are various sizes of wind turbines. The larger commercial scale turbines range in size from 100 kilowatts to several megawatts. These larger scale units are typically grouped together on wind farms. There are also off-shore versions of these wind farms. Denmark has been a leader in the development of wind power generation. Danish company Vestus represents about 23 percent of the global production of wind turbines. Europe has a target of 12 to 14 percent of electrical generation from wind by 2020 the American target is 20 percent by 2030. This will mean a tremendous expansion in the market for wind turbine construction. The U.S. is demonstrating the fastest growth in wind power generation closely followed by China. The province of Ontario is the Canadian champion. There is also steady growth in small turbine production. Some farmers in Ontario have installed wind turbines on their land. This helps reduce energy costs. At the times when the turbines produce more electrical energy than the farm needs they can Feed the extra back to the grid and the farmer is compensated for this contribution. In the last few years residential wind energy has experienced significant growth. There are an increasing number of people who choose to live off-grid. In some cases it is very expensive to bring in conventional electric power because of the distance from existing power lines. Quite often it is a commitment to be self-sustained. residential wind turbines have become more efficient and more reliable making this feasible. Often a home owner will set up a solar array to provide energy when there is insufficient wind to meet power needs. Both wind and solar power require a battery storage system to keep an even flow of electricity. Also, a gasoline or diesel generator will probably be necessary to have an uninterrupted flow of electricity. Currently, residential wind energy is the fastest growing sector in the renewable energy market. There is good reason to believe that there will continue to be much growth in the residential wind energy sector for years to come. The company Evolve Green is an established Canadian company that carries a wide range of wind turbines. They ship to Canada, the U.S. and many international locations. Prices are in USD but include all costs and hassles involved with bringing the units into Canada . They deal with all warranty claims and maintain replacement parts.
