Windturbines for Clean Energy

Wind energy or often called as well wind power specifies a technology by which the wind is used to generate mechanical power or electricity.

Along with water, it has been utilised since centuries as a reliable power generation source.

Wind starts to blow when the atmosphere is unevenly heated i.e. by the sun or irregularities on earths surface.

The propellors of wind turbines turn in the moving air and power a generator which in turn produces electric current.

The major leap for this technology was made possible by the use of new materials, allowing to manufacture turbines and propellers, bigger then ever before, onshore as well as offshore.

Modern windturbines can generate according to the present standard up to 2 MW with a single mast. Therefore  it  has become possible to build large windparks feeding the electricity grid with power.

But not only the big size is of interest.

Especially remote areas and farms without grid connection do have needs to be supplied with energy in order to power their electric machines. Generation of power using fossile fuels is often difficult, as spare parts, oils and operating medias are costly and their availability sometimes limited.

Windturbines are therefore, depending on the specific location, an ideal tool to provide electricity to operate pumps for irrigation or in combination with other systems power entire villages.

In the last years investment costs for windturbines showed an decreasing trend and, if compared with fossile fuel generation on the long run, is most competitive due to minimal maintenance costs and virtually no-operating cost.

Windturbines are available in different designs and various capacities.
