Wind Power As An Alternative Energy Source
Alternative sources of energy are very much a topical issue nowadays, given how costly fuel has gotten. One form of energy source that is being talked about is wind energy, and the efficiency of wind farms. Utilizing wind as a source of energy means having a renewable power that is incredibly clean. Wind is triggered by shifts in the temperature on the ground, which comes from the heat of the sun, so in fact wind power could be said to be sourced from solar power. Harnessing the wind thus creates electricity.
Numerous nations are now using wind farms as a means to fully use what power can be created by the wind. Working like propeller blades but in reverse, the power of the wind is gathered by the large blades of a number of wind turbines that have been erected in a suitably windy area. These farms are able to produce electricity in huge amounts, when the wind turbines work unitedly. The potential of wind farms will become clear when you are familiar with how they operate. The blades are situated on a shaft, and when the wind blows, it turns the blades and in essence the shaft. The turning of the shaft starts up a generator from which action electricity is generated. It utilizes the same principles as hydropower generation, except that wind power instead of flowing water is utilized.
Sufficient energy for a town or bigger area requires many turbines, because one is hardly sufficient for a home or modest farm. When there is a large grouping of wind turbines, such as a wind farm, working unitedly, much electricity can be produced. Whole towns can be run by the energy that is stored in battery-like storage cells, or existing utility grids. Today wind turbines are so state-of-the-art that they can use wind coming from any direction, even when it is from inconsistent, variable angles.
The efficiency is enhanced as well when the turbines are taller, or if they have larger blades. Computing the efficiency of wind turbines is made tough by the complexity of factors involved. No two wind farms are identical, as a result of the variation in terrain, wind and turbine size. Nonetheless, the typical turbine converts about 20% of the power in wind to electrical energy. Prime production efficiency is reached when the wind blows at no less than 5 miles per hour, and not more than 20 mph.
Although it is not as constant as solar, wind power is more efficient, estimated as 20% efficient versus solar at roughly 14%. Wind technology is progressing, and in comparison with other renewable energy sources, it is favorable. It is becoming an important alternative energy source, but it might take a while for the entire world to jump on board. One country that’s investing a great deal is Germany.
