Wind energy, like all energy sources, has the potential to harm the environment by reducing, fragmenting, or degrading habitat for wildlife, fish, and plants. Additionally, rotating turbine blades might endanger flying fauna such as birds and bats. Because of the potential for wind power to have a negative impact on wildlife, and because these difficulties could delay or prevent wind development in high-quality wind resource areas, impact reduction, siting, and permitting issues are among the wind industry’s top goals.
WETO supports in projects that strive to describe and understand the impact of wind on wildlife on land and offshore to address these concerns and encourage environmentally sustainable growth of wind power in the United States. Furthermore, through centralized information hubs like Tethys, WETO engages in operations to collect and disseminate scientifically rigorous peer-reviewed studies on environmental consequences. The office also invests in scientific research that allows for the development of cost-effective technology to reduce wildlife impacts at both onshore and offshore wind farms.
WETO strives to foster interagency collaboration on wind energy impacts and siting research in order to ensure that taxpayer monies are used wisely to solve environmental challenges associated with wind deployment in the United States.
- For more than 24 years, the office has supported peer-reviewed research, in part through collaborative relationships with the wind industry and environmental groups including the National Wind Coordinating Collaborative (NWCC) and the Bats and Wind Energy Cooperative.
- The NWCC was established in 1994 by the DOE’s wind office in collaboration with the National Renewable Energy Laboratory to investigate a wide range of issues related to wind energy development, such as transmission, power markets, and wildlife impacts. The NWCC’s focus has evolved over the last decade to addressing and disseminating high-quality information about environmental impacts and remedies.
- In May 2009, the Department of Energy’s wind office announced approximately $2 million in environmental research awards aimed at decreasing the hazards of wind power development to vital species and habitats. Researchers from Kansas State University and the NWCC’s Grassland Community Collaborative published a paper in 2013 that revealed wind development in Kansas had no significant impact on the population and reproduction of larger prairie chickens.
- The Bats and Wind Energy Cooperative has been involved in numerous research projects funded by DOE’s National Renewable Energy Laboratory since its inception in 2003, including studies evaluating the impact of changing the cut-in-speed of wind turbines (the minimum wind speed at which wind turbines begin producing power) and the use of ultrasonic acoustic deterrents to reduce bat impacts at wind turbines.
- Through a competitive funding opportunity, WETO is also financing research and development projects that increase the technical preparedness of bat impact mitigation and minimization solutions. Bat Conservation International, Frontier Wind, General Electric, Texas Christian University, and the University of Massachusetts are among the companies, universities, and organizations receiving funding from the Energy Department to field test and evaluate near-commercial bat impact mitigation technologies, which will provide regulators and wind facility owners-operators with viable and cost-effective tools to reduce bat impacts.

The Status and Findings of Developing Technologies for Bat Detection and Deterrence at Wind Facilities webinars hosted by the National Wind Coordinating Collaborative provide project updates and testing findings as of March 2018.
- WETO chose six teams in 2016 to work on improving solutions that will safeguard eagles that share airspace with wind turbines. For breakthrough, vital eagle-impact minimization technology research and development projects, more nearly $3 million was allocated across the six teams. The research financed by this grant will equip wind farm owners and operators with practical and cost-effective strategies for reducing potential eagle impacts. This important study expands on the Energy Department’s efforts to facilitate wind energy deployment while also ensuring animal coexistence by addressing siting and environmental concerns. If the study is successful, it will safeguard wildlife while also giving new tools for the wind industry to reduce regulatory and financial concerns.
- WETO is a supporter of research on biological interactions with offshore wind turbines. With this funding, researchers are gathering crucial data on marine life, offshore bird and bat behavior, and other factors that influence the deployment of offshore wind turbines in the United States. The Biodiversity Research Institute and a diverse group of collaborators, for example, completed the largest ecological study ever conducted in the Mid-Atlantic to produce a detailed picture of the environment in Mid-Atlantic Wind Energy Areas, which will aid permitting and environmental compliance for offshore wind projects.
WETO also collaborates with other federal agencies to create recommendations to help developers comply with statutory, regulatory, and administrative requirements for wildlife protection, national security, and public safety. The Wind Energy Technologies Office, for example, collaborated with the Department of the Interior on the Land-Based Wind Energy Guidelines and Eagle Conservation Plan Guidance.
What are the three disadvantages of wind turbines?
Wind energy’s disadvantages
The proportion of rural patients reporting harmful effects from exposure to industrial wind turbines is expected to rise in Canada, according to family physicians (IWTs). Reduced quality of life, irritation, tension, sleep disturbance, headache, anxiety, depression, and cognitive dysfunction have all been reported by those who live or work in close proximity to IWTs. Anger, grief, and a sense of unfairness have all been experienced by some. Wind turbine noise, infrasound, unclean electricity, ground current, and shadow flicker have all been suggested as possible causes of symptoms. 1 Patients experiencing adverse effects from IWTs may have severe and pervasive symptoms, and may feel further victimized by a lack of caregiver comprehension. Family physicians should be aware of this.
Do windmills have a negative impact on property values?
Wind energy has proven to be beneficial to rural areas. Rural towns have reaped major benefits, whether in the form of new job possibilities, increased county revenue, or direct compensation to landowners.
Any new discovery, though, comes with its own set of risks. Local citizens are frequently concerned about the impact of a wind farm on property values. Several studies have looked into the impact of wind farms on property values.
In 2013, the Lawrence Berkeley National Laboratory completed a research that used data from the sales of over 50,000 properties in 27 counties across nine states. With 1,198 sales within one mile and 331 sales within half a mile near wind projects, these properties were all within 10 miles. Data was also used from before a project was announced, during the post-announcement, pre-construction period, and during the project’s operation. The study discovered no indication of a pricing effect on properties near wind turbines.
While wind farms do not appear to have a significant impact on property values, site selection is still a critical component of wind energy development. Developers, in collaboration with county and community leaders, must figure out how to address concerns and mitigate the effects of new development while allowing landowners to host wind turbines if they so desire.
Identifying issues and concerns of local citizens, frequently through public forums to debate proposed projects and provide information, is a good beginning step. These discussions can provide an opportunity for county authorities to receive information that will help them make choices concerning local rules, as well as an opportunity for developers to answer questions and use comments to improve their projects.
Other local difficulties can be avoided or managed with careful siting and fair, well-informed requirements. Rural communities can collaborate with developers to improve wind energy projects and continue to profit from new renewable energy sources.
What is the minimum distance between a house and a wind turbine?
Your expert installer should be able to assist you in determining the ideal position for your wind system. The following are some of the general considerations they will address with you:
- Considerations for Wind Resources If you reside in a hilly area, be cautious when choosing an installation location. On the same land, if you put your wind turbine on top of or on the windy side of a hill, you’ll have better access to prevailing winds than if you put it in a gully or on the leeward (sheltered) side of a hill. Within the same property, you can have a variety of wind resources. You need to know the prevalent wind directions at your site in addition to measuring or finding information about annual wind speeds. You must also consider existing impediments such as trees, buildings, and sheds, in addition to geological formations. You must also account for future obstacles, such as new structures or trees that have not yet grown to their maximum height. Your turbine must be 30 feet above anything within 300 feet, and it must be located upwind of any buildings or trees.
- Considerations for the System Only tiny wind turbines that have been tested and certified to national performance and safety standards should be considered. When deciding where to put the tower, make sure there’s enough area to lift and lower it for maintenance. If your tower is guyed, make sure there’s enough space for the guy wires. You must also consider the length of the wire run between the turbine and the load (home, batteries, water pumps, etc.) whether the system is stand-alone or grid-connected. The wire resistance can cause a significant quantity of electricity to be lost; the longer the wire ran, the more electricity is lost. The cost of installation will rise if you use more or larger wire. When you use direct current (DC) instead of alternating current (AC), your wire run losses are higher (AC). Inverting DC to AC is recommended if you have a long wire route.
Is it true that wind turbines are noisy?
Wind turbines are no exception to the rule that everything with moving parts makes noise. Wind turbines, on the other hand, are normally quiet in operation, especially when compared to the noise produced by road traffic, trains, airplanes, and building activities, to name a few.
