Existe RISCO na ENERGIA EÓLICA? Qual o RISCO da ENERGIA EÓLICA?

Are there risks associated with wind energy production? Hey Engineering Lovers, we know that the demand for affordable and renewable energy has reached a high level lately. And one of the leading candidates to potentially replace fossil fuels is also one of the oldest is wind energy.

It has been used for centuries to grind grain and power ships, and as far back as the 1930s it has been used to generate electricity. But over the past 40 years, as the demand and price of energy have steadily increased, so have efforts to make wind energy a viable option for large-scale electricity production. The potential of wind turbines, which convert kinetic energy into electrical energy, has been promoted at every step.

But what about the risks? After all, these wind turbines can be colossal, measuring more than 122 meters tall, weighing around 400 tons and equipped with rotating blades that can reach 91 meters each or more. First, let's look at some of the financial risks of wind energy.

Subsidies and incentives offered by the government are creating a sense of urgency for utility providers and cooperatives to install wind farms. But even with financial cuts, wind energy is an operation that is unfortunately still very expensive. According to the American Wind Energy Association, building a 50-megawatt wind farm, which on average would be done with 25 wind turbines, carries an initial cost of about $65 million, and that's before a single kilowatt of electricity.

be generated. In other words, this is the initial investment you need before you start generating energy with it. That's a pretty high price for a venture that completely depends on something as unpredictable as the wind.

Another risk associated with wind farming is destroying the landscape with acres and acres of huge turbines. Thinking about the same hypothetical 50-megawatt wind farm we just talked about, for example, it would require almost 16 square kilometers of total area, about 0. 64 square kilometers per turbine.

Thus, even in relatively isolated areas, these installations can transform a pristine desert area into an industrial monstrosity. Wind turbines can also cause real bodily harm to both humans and wildlife in areas close to their installation sites. Looking from a distance, the blades appear to move slowly, but the top speed of these turbines can approach 320 kilometers per hour, creating deadly obstacles for birds.

For example, birds of prey are particularly vulnerable because they hunt on open plains where visibility is high. One particularly publicized wind farm, Altamont Pass in California, has been the subject of controversy due to the impact that poor planning has had on the bird population. According to the Center for Biological Diversity, about 1,300 eagles, hawks, and other species are killed every year because wind turbines were built along a critical migration route.

But it's not just the birds, but also the people. As with any developing technology, progress and understanding often happen simultaneously. The detachment of a wind turbine blade, although rare today thanks to improvements in design, can occur, and it becomes a very large and very dangerous projectile.

Likewise, wind farms operating in cold climates are also susceptible to ice formation. This accumulated ice can fall or be released by the turbines, potentially endangering people and neighboring properties. There are also more subtle health risks from wind farming.

In a book called "Wind Turbine Syndrome: A Report on a Natural Experiment" by Dr Nina Pierpont, she describes a condition called "wind turbine syndrome" in which wind farms pose real health risks to nearby residents. The subsonic noise generated by the turbines is believed to cause illnesses ranging from headaches and insomnia to dizziness and even depression. This can already be seen in some regions of northeastern Brazil, where residents who live close to these turbines have suffered from various symptoms described in the book and some end up having to leave these regions because they cannot bear to live close to them.

And visually, the oscillating effect of the rotating turbines can cause vertigo and even convulsions. For all its promises, wind energy has its own set of risks that must be weighed against the benefits. After all, it wasn't long ago that oil was hailed as a cleaner, more efficient alternative to coal and helped power the world during the industrial revolution.

To ensure that the installation of wind farms is truly sustainable, it is crucial to carry out comprehensive and careful assessments in several areas. This includes detailed environmental impact studies to understand the potential impact on local wildlife, landscape and ecosystems. Furthermore, financial viability assessments must be conducted to ensure that wind energy investments are economically sound in the long term, considering construction, maintenance and operation costs.

It is also critical to involve local communities from the early stages of planning, ensuring their concerns are heard and addressed in a meaningful way. Additionally, advanced impact mitigation technologies, such as bird detection systems and noise minimization strategies, can be implemented to reduce negative impacts to wildlife and human health. These comprehensive assessments are essential to ensure that wind energy is developed responsibly and sustainably, maximizing benefits while minimizing risks and adverse impacts.

I usually say that there is no perfect solution for anything. The solution for a transition to a clean energy matrix will actually be a set of solutions, merging technologies and uses of different forms of energy capture to compose a truly clean matrix. And I also tend to emphasize that there is no single, perfect solution to the energy challenges we face.

Instead, the transition to a clean energy mix will require a multifaceted approach, combining diverse technologies and energy capture methods. The true solution will lie in a set of complementary solutions, which incorporate a variety of renewable sources, such as solar, wind, hydroelectric and biomass, among others. It's the same as thinking about not putting all your eggs in one basket.

This diversification not only increases the security and reliability of energy supply, but also contributes to a truly clean and sustainable matrix. By merging technologies and taking advantage of the unique characteristics of each form of energy capture, we can create a more resilient energy system aligned with the needs of the environment and society.
