Wind energy has been a cornerstone of sustainable energy for several years but has recently come under fire by several organizations and, most notably, President Donald Trump, who has long been an opponent of the concept. Let’s look into what the problem is.
Environmental and wildlife concerns
One big problem with wind turbines is that they pose a significant danger to wildlife, especially birds and bats, with some species already facing frighteningly low numbers. The U.S. Fish and Wildlife Service estimates that wind turbines are responsible for approximately 140,000 to 500,000 bird deaths annually.
Trump, along with a number of other organizations, also believes that wind turbines could be harmful to whales due to environmental disruption caused by increased noise and vessel traffic, which might lead to a higher mortality rate. However, scientists need more research to back this claim up, and there are many opponents to the idea.
Economic and aesthetic criticisms
Trump argues that wind energy is inefficient and heavily reliant on subsidies, making it less viable than traditional fossil fuels, though the price has been coming down in recent years. The observed power density of wind energy is also much lower than theoretical estimates. Wind turbines capture kinetic energy from the wind, but only a fraction of that energy converts into electricity, and the efficiency decreases as you add more turbines within a region due to aerodynamic interference (turbine wakes interacting with each other).
Wind turbines can warm the ground by altering local atmospheric dynamics, particularly through a process known as vertical mixing, leading to a significant rise in temperature in the areas where you find them.
Wind turbines are also criticized for their aesthetics, potentially lowering the value of your home if they are within five miles, but that seems to be diminishing as more people become accustomed to seeing them.

FAQ
Are wind turbines noisy?
Wind turbines produce some noise, but modern designs aim to minimize this. The sound is usually a low-frequency “whooshing” that decreases with distance.
Do wind turbines affect weather patterns?
Wind turbines can affect local weather by altering airflow and atmospheric dynamics. Large-scale wind farms may slightly change wind speeds and surface temperatures in the surrounding areas.
Are wind turbines recyclable?
Most parts of a wind turbine, like steel and copper, are recyclable, but blades, often made from composite materials, are harder to recycle.
How tall are wind turbines?
Modern wind turbines typically stand 280-400 feet tall, with blades that can span over 200 feet. Offshore turbines are often larger.
