Wind turbine
Produced energy from wind is renewable. The main part of producing energy out of wind is the wind turbine. In Swiss we got over 57 of them. But how do they produce energy out of wind? It’s simple. The turbines have three rotor blades which rotate when there is enough wind blow. By rotating, they start an engine which produces energy and uploads the energy into the power line. It is important for the wind farm to be able to store electricity so that it can also be used when the wind turbines are at a standstill - for example during maintenance work or difficult weather conditions in alpine winter. For space reasons, it will likely result in battery storage - six stores the size of shipping containers. Each storage facility must be able to store the daily production of electricity from a wind turbine.[Wind turbine, 2010] [How to save wind energy, 2017]

Another type of mechanism with windpower is the windmill. In the middle age the farmer used the windmill to produce flour out of wheat.

Wind turbine in Switzerland:
In Switzerland there are not so mandy windturbine, thats because siwtzerland is not a typical country for them. But in the canton of jura and in some mountains there are windtrubine. Switzerland has not so much space for those big windturbine,but in this case there are some ‘parks’ weher it has some windtubine that are enough. They are mostly build in industriezone.

Change of Windturbine over Decades:
Between 1978 and 2010, the wind speed declined by an approximate 0.3 kilometers per hour per decade. From 2010 to 2017, however, the wind speed rose by 0.9 kilometers per hour. According to the survey, the electricity that could be selected from a conventional system using the wind has increased by a circular 17% since 2010. In addition, the increase was 22% in North America and Europe, and within 11% in Asia. So from year to year there are not more windturbine in switzerland, only when they find some free space they can build some even if the wind speed increases.
