The wind energy sector reached record-high production rates in 2020. As eco-consumer demands increase, we can expect the industry’s success to follow. Renewable energy expansions can improve atmospheric conservation and generate ecological challenges.

Combining technology and nature has its downfalls, interfering with habitat and resource stability. Wind turbines specifically impact winged animals, altering their transportation environment. Environmental engineers and scientists evaluated the interactions between birds and wind turbines and developed low-impact technology.

The Importance of Wind Energy

President Biden established a national carbon neutrality goal upon taking office. He plans on achieving the objective by developing an electric grid. We can create enough energy to support the project by diversifying the power sources.

Wind turbines achieve a maximum 50% power efficiency rate in optimal weather conditions. Expanding on and off-shore production projects can support the transition from fossil fuels to renewable energy sources. Adopting clean electricity is essential to preventing further climate change effects.

Conventional energy sources release greenhouse gas emissions during combustion. Naturally, Earth relies on a consistent atmospheric composition, generating life-sufficient surface temperatures. They support the global ecosystem’s stability, preserving resources and humanity’s longevity.

Organically, the atmosphere absorbs sunlight, produces heat, warms the surface, reabsorbs additional energy and emits it to space. When greenhouse gases invade the environment, they increase the heat production rate. Additionally, they trap excess energy in the atmosphere rather than sending it to space.

Over time, greenhouse gases increase the global temperature. Wind energy offers an emission-less alternative, preventing the enhanced greenhouse effect. Expanding production can improve the sustainability of the energy sector and prevent adverse climate change effects.

Ecological Challenges

Wind power’s interference with biodiversity generates significant concern amongst environmental professionals. Turbines create fatal challenges for birds and bats in their regions. A team of researchers found that wind energy systems kill up to 500,000 birds annually.


A variety of factors influence the deadly collisions between bats and turbines. Inefficient planning and mapping strategies place production systems in migratory routes, decreasing safety. The color of turbines also reduces their protection of biodiversity.

Birds and bats may mistake the reflective turbine surface color as a water source. They fly into the system at full speed, expecting a soft landing. Some animals also misidentify the devices as trees for roosting and fly into the rotating blades.

Professionals can alter the structure of turbines, adding collision prevention features. Installation workers may also study the migration patterns and limit interferences. A team of researchers at Duke University explored the associated ecological challenges and developed an effective solution.

Sustainable Solutions

The additive technology utilizes ultrasonic acoustics, signaling the presence of a turbine. Professionals searched for a sound that prevents bats from entering certain regions. When they identified the noise, they recorded it for reuse.

Researchers placed speakers around a turbine and played the frequency on a loop. The high-pitched acoustic is out of a human’s hearing range, decreasing noise pollution. Turbine owners can use the technology to keep bats away from wind farms.

They can also limit all bird collisions by altering the system’s color. Decreasing the reflectivity of a turbine could reduce fatal interactions. Adding a natural or alerting color to the device may enhance biodiversity in designated regions.

Engineers also developed a protective turbine alternative that significantly reduces collision fatalities. Ampyx Power released a wind power production drone without a tower. The device connects to a ground-level generator by a tether.

The drone accesses peak energy production heights, extending upwards of 660 feet. It generates more electricity than a traditional turbine and decreases collision risks. The drone circulates in the air, collecting and generating electricity for immediate use.

Vortex is another sustainable wind power production company revolutionizing the energy sector. They developed a less biodiversity degrading device that generates clean electricity without turbine blades. The bladeless model limits collisions by removing high-speed, rotating elements.

Large turbines with heavy blades can reach 180 miles per hour rotation speeds. Their fast circulation sucks in and hits many winged species. Removing blades from turbines can successfully decrease bird fatalities.

The Importance of Biodiversity

Protecting birds and other winged species is essential to the stability of Earth’s ecosystem. They ingest seeds and disperse them through their droppings when they travel. Without their expansion of certain species, they may go extinct.

Additionally, bats pollinate flowers and promote plant growth. Protecting trees and other vegetation decreases atmospheric pollution. A single tree can filter 48 pounds of greenhouse gas emissions annually. Processing surface pollution limits the accumulation of pollutants in the environment.

When we preserve bird species, we also improve atmospheric conditions. Optimizing wind turbines to enhance biodiversity can further decrease emissions. Together, environmental conservation efforts and renewable energy production can prevent climate change.

Improving Regulations

You can help protect bird species and the global ecosystem by voting for change. We must improve our on and off-shore wind power production regulations. Additionally, you can reach out to your local government officials and develop species protection programs, fighting for efficient migration mapping before installing turbines.
