Effects on Wildlife

Wind energy is a renewable source of power, but it does have some impacts on wildlife. Here’s a breakdown of the two main effects:

Direct Impacts:

• Collisions: Birds and bats are most susceptible to collisions with wind turbine blades. This can cause fatalities, especially during migration periods.
• Some bird species, like raptors (hawks, eagles), are more at risk due to their hunting behavior which can place them in the path of moving blades.

Indirect Impacts:

• Habitat Loss and Fragmentation: Construction of wind farms can disturb wildlife habitat, causing animals to avoid the area. Additionally, the presence of turbines and access roads can fragment habitat, making it harder for animals to move freely.
• Noise Pollution: The operation of wind turbines creates noise that can disrupt wildlife communication and behavior. This can be particularly stressful for animals that rely on sound for hunting, navigation, and mating.

Mitigating the Effects:

The wind energy industry is constantly working on ways to minimize these impacts. Here are some strategies:

• Site Selection: Carefully choose locations for wind farms that avoid important wildlife habitats and migration routes.
• Turbine Design: Developing and using turbine designs that are less visible to birds and bats, or that deter them from flying near the blades. This can include painting blades black or white to increase visibility or using deterrents like ultrasonic sound devices.
• Curtailment: Stopping turbine operation during low-wind periods or peak migration times to reduce the risk of collisions.

Overall Impact:

While wind energy does have some negative effects on wildlife, the industry is working to minimize them.  Studies suggest that wind turbine fatalities are a relatively small contributor to overall bird and bat deaths compared to other human activities like collisions with buildings and cars.

Benefits Off-Grid Communities and Businesses

Implementing a wind energy project for off-grid communities requires careful technical considerations to ensure its effectiveness and sustainability. Here are some key factors to think about:

Wind Resource Assessment:    

• Wind Speed and Availability: The most crucial aspect is understanding the wind resource at the potential project site. Anemometer towers are used to measure wind speed and direction over an extended period. This data is then analyzed to determine if wind speeds are sufficient and consistent enough to generate usable electricity.
• Site Selection: Factors like topography, prevailing winds, and proximity to residences or sensitive areas need to be considered. Wind turbines should be placed in areas with good wind flow and minimal obstructions.

System Design and Sizing:   

• Power Needs: A thorough assessment of the community’s total electricity demand is needed. This will determine the size and number of wind turbines required to meet their needs.
• Turbine Selection: Choosing the right size and type of wind turbine is crucial. Factors like wind speed variations and noise limitations need to be considered. Smaller, community-scale turbines might be more suitable for off-grid applications.
• Battery Storage: As wind is not constant, battery storage systems are essential to store excess energy generated during high-wind periods and provide power when wind speeds are low. Battery capacity needs to be carefully sized based on the community’s consumption patterns and wind resource variability.

Technical Expertise:  

• Project Development: Expertise is needed to navigate permitting processes, conduct feasibility studies, and design the overall wind energy system.
• Installation and Maintenance: Qualified technicians are required to install the wind turbines, batteries, and other system components. Off-grid communities might need to consider partnerships with wind energy companies for ongoing maintenance or training local personnel.

Financial Considerations:   

• Costs: The upfront costs of wind turbine purchase, installation, and battery storage can be significant. Exploring financing options, grants, or subsidies available for renewable energy projects can be beneficial.
• Operation and Maintenance: Ongoing costs for maintenance, repairs, and battery replacements need to be factored into the overall project budget.

Social and Environmental Considerations:  

• Community Engagement: Open communication and engagement with the community throughout the planning process is essential. Addressing concerns about visual and noise impacts is crucial for project acceptance.
• Environmental Impact Assessment: The potential environmental impacts of the project, such as bird and bat collisions, need to be evaluated. Mitigation strategies might be necessary to minimize these impacts.

Additional Considerations:

• Hybrid Systems: For off-grid communities with existing diesel generators, integrating a wind energy system can create a hybrid system. This can reduce reliance on diesel while maintaining backup power during low-wind periods.
• Scalability: Starting with a smaller wind energy system and gradually expanding capacity as the community’s needs grow can be a viable approach.

By carefully considering these technical, financial, and social aspects, off-grid communities can implement wind energy projects that provide clean, reliable, and sustainable power for their residents.

Assessment of Barriers to Wind Energy Development Using Analytic Hierarchy Process

Off-grid wind power systems: Planning and decision making

Wind Energy Essential

Limited Noise

Noise Levels:

• Wind Turbine Noise:
  • A study by the American Wind Energy Association (AWEA) shows that modern wind turbines typically generate noise in the range of 35-50 decibels (dB) at a distance of 500 meters [1].
  • For comparison, here are some common noise levels:
    • Refrigerator hum: 40 dB
    • Conversation at a normal voice level: 60 dB
    • Traffic noise on a busy highway: 80 dB or more [2]
• Regulations:
  • Many countries and regions have regulations that limit wind turbine noise levels at specific distances from residences. These limits are often set around 45-50 dB at a certain distance (e.g., 500 meters) [3].

Noise Reduction Advancements:

• Blade Design:
  • Newer wind turbine blades are designed with aerodynamic features that reduce noise generation. These features include:
    • Serrated edges to reduce whistling sounds
    • Smoother airfoil shapes for quieter operation [4]
• Operational Adjustments:
  • Wind turbine blades can be pitched at specific angles during low-wind conditions. This reduces their rotational speed and consequently, noise generation [5].
• Siting Strategies:
  • Careful placement of wind turbines away from residences can significantly reduce noise impact. Studies suggest that increasing the distance between turbines and homes by just 100 meters can cut noise levels by 5 dB [6].

Impact on Health:

• Studies:
  • The World Health Organization (WHO) reviewed numerous studies on wind turbine noise and health impacts. They concluded that there is “limited evidence” that wind turbine noise below regulatory limits causes adverse health effects [7].

Addressing Concerns:

While the data suggests limited noise impact at regulated levels, it’s important to acknowledge that some people might find the low-frequency sound from wind turbines bothersome.  Open communication and community engagement throughout the wind energy project development process are crucial.  Addressing noise concerns and implementing mitigation strategies (e.g., proper siting, and noise monitoring) can help ensure project acceptance.

Behind the Blades

Amy Robertson Takes on the Complexities of Floating Offshore Wind Energy

As a kid growing up in Clear Lake City, Texas, home of the Johnson Space Center, Amy Robertson was immersed in what was happening at the National Aeronautics and Space Administration. Just about everybody she knew—including her dad—either worked there or had parents who did. So it made perfect sense that, as a kid, she dreamed of joining the space industry.

But not, she emphasizes, as an astronaut. When her dad brought her to work and let her try out the astronaut-training centrifuge, she threw up. And when Alan Shepard visited her classroom and demonstrated how astronauts use the restroom in space, she was officially out. (“Who wants to do that stuff?” Robertson thought.)

Robertson did pursue her space dreams, though, ultimately earning a Ph.D. in aerospace engineering. But the best use of her skills and education seem to be right here on Earth, as offshore wind energy group manager at NREL.

“I was the first person hired at NREL that was devoted to offshore wind,” Robertson said. “But I had no experience in wind! None.” Luckily, that degree in aerospace engineering came in handy. “I'm a structural person, and the crazy thing about floating wind is that it's a structures problem. It's a wind aerodynamics problem, and it's a hydrodynamics problem, too. Finding someone who's an expert in all three is almost impossible.”

So, in , Robertson took her structural experience and her love of a challenge and applied it to the nascent field of offshore wind energy. We caught up with her to find out more about her journey before coming to NREL—and why it’s been an exciting ride ever since. Read the full interview.
