The commercial use of wind turbines dates back to the First World War. These were used to power hospitals, schools and railroads. With the onset of mass production, the need for such a utility also became evident. It is now possible to make electricity from the natural energy of the wind. One of the reasons why such an effort was necessary was the post-war world where food and commodity prices were extremely high. This meant that there would be little left over after the war to feed the needs of the people.
There are many factors which determine the strength and the level of air density at a particular location. They are well known and can easily be predicted. This information on the atmospheric conditions will be helpful in determining the amount of energy which can be produced by a wind turbine. Among these factors are the local weather conditions, the wind speed and the density of the air.
To compensate for the local lack of wind energy, the developers of wind turbines came up with ways of increasing the strength of their blades. The new turbines that are being installed nowadays are much stronger than those which were first put up. In fact, the new ones are now more than twice as strong as the old ones. The development of the technology is also a factor why electricity generation from such turbines has become efficient nowadays. For one thing, the tips of the blades have been made much sharper so that they can catch the most wind flows.
The question “how do wind turbines work?” has still not been adequately answered. There are theories that this type of device draws energy from the wind or from some kind of alternate source. But to answer it, researchers have developed better ways of converting the rotational energy into electricity. For more info https://reblade.dk.
