The arguments that could be used to challenge the idea of using wind power to provide electricity to the whole country is that there is a difficulty in capturing wind, wind power causes visual and sound impacts, as well as an impact on fauna.

Explanation:

Wind energy is a widely used method for obtaining power through wind power, which drives windmill and windmill-like mechanisms connected to a generator that produces electricity.

The main advantage of wind energy is that it is considered a clean energy, that is, obtained from renewable sources and without generating any kind of polluting waste during its production and consumption.

Although wind energy is one of the best options for obtaining energy from renewable and clean sources, it is possible to see some negative points of this technique. These negative points are:

Difficulty catching wind: Because it is totally dependent on wind and air currents, it is possible that an unfavorable climate will compromise production; Visual Impact: The installation of wind turbines can cause major changes in the landscape, either due to the space required to install the equipment or the size of the necessary mechanisms; Animal Impact: Modifications related to the installation of wind energy equipment change the habitat of several animals, especially migratory birds, so that they have to adapt; Sound impact: Wind energy production is very noisy, which can frighten animals and disrupt the daily lives of people living in areas near the wind farm.
