Will Wind Power Ever Be An Essential Energy Source?
With the expense of fuel these days, there is much talk about alternative energy sources. One form that is being discussed is wind energy, and the efficiency of wind farms.
Using wind as an energy source means having a renewable power that is unbelievably clean. Wind is triggered by variations in the temperature on the ground, which comes from the heat of the sun, so as a matter of fact wind power could be said to be sourced from solar power. The wind is then channeled to generate electrical energy.
Wind farms as a large-scale method of capturing the energy produced by wind has been adopted by many countries. Much like the propellers on an airplane, the blades of wind turbines, erected in large numbers in one location, are used to capture the power of the wind. These farms are able to generate electricity in huge amounts, when the wind turbines work together. An understanding of the principles involved in wind farms will illustrate their potential effectiveness. The way wind turbines operate is, the propeller turns a shaft when the gusts of wind turn the propeller blades. The shaft that is turning is linked to a generator, which is cranked by the spinning action, making electric power. Hydro-power is exactly the same, except for using water instead of wind as the source of energy.
One turbine by itself will not produce energy for more than a house or farm, so it takes more than one to produce energy for a large area. When there is a large grouping of wind turbines, such as a wind farm, working together, much electric power can be created. Whole communities can be run by the energy that is stored in battery-like storage cells, or existing utility power grids. The technology behind wind turbines has matured remarkably, so that now they are effective irrespective of which way they face compared to the wind - even swirling winds can be utilized.
Larger blades and higher turbines also make for increased efficiency. Since there are many factors that have to be analyzed, it is hard to determine the exact efficiency of wind turbines. There is no constant, when it concerns wind farms, since they change so much in terrain, size of turbines, and the amount of wind. In general, the amount one turbine will convert the energy in wind to electric power is more or less 20 percent. When the wind is blowing between 5 and 20 miles an hour, that is when the production is the most efficient.
Wind power with an efficiency rating of 20 percent is higher than solar by five to seven percent, but solar is much more constant than wind. Wind technology is progressing, and when compared to other renewable sources, it is favorable. It is becoming an important source of alternative energy, but it might take a while for the whole world to jump on board. One country that's investing a lot is Germany.
