Environmental aspects

ENVIRONMENT

is important for us

RES sector development is a result of economic, technological, social and, above all, environmental conditions.

The demand for energy increases, however energy production may soon be suppressed by tightening the requirements on environmental protection and exhaustion of the traditional raw materials.
Renewable energy provides self-sufficiency for each country, that chooses the solution. It is constantly evolving technology, stimulating the development of regions where wind farms are constructed.
The problem of power industry are the requirements for environmental protection. Poland has to reduce CO2 emissions, reduce energy consumption, produce it from renewable sources. Otherwise our country will pay a multimillion penalties, that each of us will suffer.

Besides the beauty of moving blades of a wind turbine on a background of Polish fields and meadows, nature protection is the most important. The technology of production of wind energy is emission-free. By choosing it, we protect the environment from excessive greenhouse gas emission.

All, above mentioned aspects argue to engage in the industry, the effects of which are beneficial to us all. We deeply believe in the success of wind energy development.

ACOUSTICS 

of the wind mills

Wind turbine, like any mechanical device, emits sound. Its intensity is not greater than the sounds of the devices surrounding us in every household. Sound is calibrated in decibels (dB). The fewer decibels, the device is quieter.

Do wind turbines emit sounds?

The noise level generatred by household Bosh equipment is as follows:

  • fridge: 40 – 50 dB;
  • kitchen hood: 57 – 71 dB;
  • dishwasher: 44 – 48 dB;
  • washng machine: 56 – 78 dB.

The acceptable sound level of the wind farm

The acceptable sound level emitted by wind farm is regulated by Regulation of the Minister of Environment of 14 June 2007 (Dz. U. 2007 r. nr 120 poz. 826) and is within 40-45 dB during night (so it is not higher than the level of noise emitted by household devices), and during the day is within 50-60 dB.

The protection for the inhabitants from excessive emission of sound

Construction of a wind power plant requires the investor to comply with the provisions of the noise. Since the production of the first noisy wind turbines a lot of years have passed and there has been a significant change related to reduction of noise emitted by the turbines. This is a result of, among others, additional silencing, appropriate profiling of blades and a reduced rotational speed.
