Wind Power Generator

A wind turbine is any device that wind energy in a usable form of energy. The most common type of wind turbine is a three-bladed wind turbine, wind energy into electricity. The wind turbine is an increasingly popular form of electricity generation, as many nations turn away from traditional energy sources, oil and toward renewable energy sources.

In a way, some wind energy from one form used to convert into another can be regarded as a wind power generator. From this perspective could even be something as simple as a sail on a sailing ship can be regarded as a wind power generator, the conversion of wind energy in the swing of the ship. A windmill attached directly to a water pump or a grain processor could also be seen as a wind turbine. This early type of wind turbine was in operation as far back as the 2nd Century BC in Persia, and the technology around the world spread over the next millennia.


More commonly, however, a wind turbine at a single device that wind energy into electricity would be considered. In this sense, the earliest devices appeared in the late 19 Century. By the end of the first decade of the 20th Century, nearly 100 generators were mounted windmills in the United States, with some producing up to 25 kW. During the 1920s and 1930s to increase the wind power generator in popularity in the United States as a source of small amounts of electrical energy in rural areas which were not attached to any type of centralized power.

With the advent of a more robust national grid, with coal and nuclear power plants, was the use of wind energy generator in the United States. Although still used in the 1960s and 1970s on farms for things such as pumping water some generators have been used to actually produce electricity. Beginning in the 1980s, this began to change, with the modern wind turbine a performance, and a growing interest in alternative energy sources, oil.

The modern wind turbine is usually on a horizontal axis, with three knives. The generator direction changing, the wind, as determined by a simple computer. They will most efficiently capture the power of wind, with as little as possible about wobble. A modern wind turbine is usually at the top of a column of some 200 to 300 feet (60m to 90m), set high and the leaves themselves are between 60 and 130 feet (18m to 40m) long. Most generators have variable speeds so that they best use the wind, and it can be turned off manually when wind speeds are too high to ensure that no harm comes to the device.

Currently, wind power accounts for only about 1% of total global energy production, or about 95 GW. Some countries have much more invested in wind energy, but with nations such as Portugal and Spain generate around 10% of its energy from wind, Denmark produces around one fifth of its energy from wind, and countries like Ireland and Germany produce more than 5% of its energy from wind .
