The use of wind is first mentioned in Egypt around 3000 B.C., it refers to the use of wind to propel boats (as can be easily guessed, we are talking about sails). Reliable historical records of windmills date back to 644 A.D. They tell of windmills from the Persian-Afghan border of Sistan. For a long time, they were mainly used to propel various types of machinery.

The first windmill to produce electricity was built at the turn of 1887-88, and its designer was Charles Francis Brush, one of the pioneers of the American electrical industry. Its design, however, did not yet resemble the wind farms we know today. The first such power plant, which produced alternating current, was not built by Johannes Juul until 1957. It was built off the coast of Denmark, and even by today’s standards it is state of the art (the construction itself). It was this event that can be considered the beginning of what we call wind farms today.

“Green Electricity.”
Due to the progressive climate crisis, renewable energy sources (RES) are receiving more and more attention. One of them is wind power plants. One of their advantages is low cost of energy – one kilowatt-hour costs up to 0.10 PLN on average. In addition, the operation of wind farms does not produce greenhouse gases. The energy produced in this way does not need to be imported. This factor has a great impact on the environment, since fossil fuels often have to be imported, which leads to significant pollution during transportation, not to mention the devastating impact on the environment during extraction and combustion. In turn, energy generated by wind is the exact opposite – it is considered one of the cleanest due to the fact that it does not emit harmful substances during operation and due to the materials used in the construction of power plants.

Eco-construction for eco-energy
The foundation of most wind farms is made of concrete. Concrete of proper quality makes the structure strong and does not require costly interventions over the long term. This means that, with the exception of the production process (which is constantly being upgraded), the operation of such a power plant does not create additional pollution. You do not need large plots of land to place such a structure – despite the height, they do not take up much space. It is increasingly common to see small windmills that can power individual buildings.

To summarize, wind farms can be a great promising solution for generating electricity. Their advantages include zero emissions, low cost of electricity generation and the longevity associated with the use of concrete. The PCC Group offers concrete and concrete element manufacturers state-of-the-art additives, a complete range of which can be found on the Product Portal.
