Busting Wind Energy Myths


Busting Wind Energy Myths

The article aims at dispelling the myths around wind energy, the technology gaining momentum rapidly in the highly developed economies. Whether it is truly economically feasible? What about environmental harms? Let’s study the most thought-provoking questions under the microscope here and now.

  1. Wind power is expensive

Wind energy is competitive in regions with moderate to high wind speed. Given the fact that the manufacture of wind energy equipment requires constructing wind turbines (50% of total cost accounts to turbine manufacturing), the entire process is deprived of utilising raw materials, reducing environmental pollution and dozens of other operational expenses.

In addition, the cost of wind energy is decreasing annually due to the new technologies, unlike the energy produced at plants running on coal or uranium.

  1. Wind power is an unreliable source of energy

Weather affects the amount of energy generated by wind power. However, it does not mean that wind farms are unreliable. Unlike modern power plants, wind power can run smoothly even in the event of a breakdown of one of the wind turbines – for the rest of the installation will work.

  1. Wind turbines during short periods of time

At full capacity wind power plant is operating only 10% of the time, despite the fact that they are built in windy areas. However, wind turbines generate electricity throughout most of functioning the time (65-80%), although the amount of energy produced can vary.

Nevertheless, none of the plants produces energy at 100% of the declared capacity on a constant basis. In addition, the sectors are often closed for repairs and maintenance.

  1. Wind turbines are inefficient

Wind turbines demonstrate nice efficiency and to prove this, an energy return can be calculated – the interval of time during which a certain amount of energy produced. Wind station, according to research by US scientists from the University of Madison-Wilson, produces 17-40 times more energy than they consume, while conventional nuclear power plants can boast only 16 times mark.

  1. Wind turbines are very noisy

The neoteric solutions in the construction of wind turbines have enabled the engineers to overcome the problem of noise. In particular, the aerodynamic noise reduced by changing the thickness of the turbine blades and their position relative to the wind direction. The level of noise, emitted by turbine at a distance of 250 m is no more noise than the noise of a conventional refrigerator.

  1. Wind turbines are dangerous to humans and animals

Wind energy is not related to the emissions of harmful gases into the atmosphere, water pollution or soil contamination. Throughout 30 years of its full-fledged functioning no significant accidents with wind turbines have been recorded.

  1. Wind turbines are expensive to maintain

As a rule, turbine farm owners have in-staff engineer team or partner with seasoned industry experts, such as Granada Material Handling, providing a broad variety of wind turbine services as well as assisting with wind turbine inspections at more than democratic prices.
