The exploitation of wind energy with the construction of wind farms has been put in action since the end of the 20th century.
According to the European Commission, wind energy is going to become the main source for the production of electricity until 2050 while the USA aim on producing 20% of electricity from wind energy until 2030. In theory, wind farms are being presented as a sustainable, renewable, and clean source of energy that doesn’t emit pollutants.
It is also considered that the construction of wind farms plays a role in improving the economy and attracting investments.
When this is put in action though, wind farms seem less “green”. Since the wind has a small energetic dynamic, in comparison to other sources, huge turbines and very big quantities of land are needed in order for the wind farms to be made which leads to trees being cut, the alteration of vegetation and the habitat of many animals and organisms. At the same time, the wind turbines set a threat to many birds and flying species that may be hit, especially if we think about threatened species or migratory birds. When it comes to offshore wind farms, the vibration that is created below the surface of the sea has a big impact on fishes and sea life.
Many residents are also objecting to these constructions because of the noise that reaches a big spectrum around the wind turbines as well as the visual destruction for specific sceneries. Lastly, it has been shown by research that the wind energy model can result in the rise of temperatures in the atmosphere by 0.24 degrees Celsius due to the movements of the turbines.
As the intentions of constructing more and more wind farms are becoming clearer and the opposition of the people is becoming more intense, we really need to think whether this solution really is environmentally right and sustainable for both the planet and its beings.
