The Clean Energy Industry’s Commitment to Bat Conservation

Bats are normally considered just another part of Halloween. But the scariest thing about bats is what the world would look like if they no longer existed. 听Often misunderstood as a species, bats play a crucial role in a healthy, thriving ecosystem. 听Bats serve as natural pest control and eat many kinds of insects, including mosquitoes. With over 1,400 species, bats help 听a year by eating insects that would harm crops and they also play a vital role in in desert and tropical climates, including 300 species of fruits like mangos and bananas.

Each October, is celebrated across the globe and raises awareness about the need for bat conservation. The U.S. clean power industry is committed to co-existence with bats when building and maintaining new energy projects and the industry has made positive strides to reduce impact on bats.

Wind and solar energy are some of the most environmentally friendly ways of generating electricity. Wind energy has one of the lowest impacts on wildlife and their surrounding habitats of any utility-scale electricity generation.鈥 Good stewardship is a core value for the U.S. clean energy industry and the industry is committed to鈥痜urther reducing its already low impact on the鈥痚nvironment, including bats.

Clean energy developers take a systematic approach to identifying wildlife impacts and engaging in initiatives to reduce if not eliminate them. The U.S. clean energy industry has a long history of partnering closely with the conservation community and federal and state regulators to solve wildlife challenges.

For nearly three decades, industry leaders have worked collaboratively with conservation partners to develop innovative solutions that support wildlife and the environment. From collaborations with the Department of Energy and , to forming the (REWI) and the Renewable Energy Wildlife Research Fund (REWRF), and in partnership with conservation and science organizations to implementing technology such as the, the clean energy industry is committed to coexistence with wildlife.

Here are just a few of the many ways the clean energy industry is aiding and researching new ways to mitigate bat incidents and ensure thriving ecosystems for our flying mammal friends.

Apex Clean Energy鈥檚 Grant Conservation Program

With the company鈥檚 core value of sustainability top of mind, Apex Clean Energy strives to not only advance the sustainability of America鈥檚 energy system as a whole, but also enhance local ecosystems and habitats where Apex鈥檚 projects are developed and operated. That鈥檚 why this ACP member company created the听.

Through Apex Clean Energy鈥檚 Conservation Grant Program, each renewable energy project commercialized by Apex contributes a sum of money, proportional to the size of the project, to support local or regional wildlife conservation, reforestation and flora restoration, protection of sensitive habitats such as grassland or wetlands, and other environmental conservation initiatives in or near project communities.

In December 2022, Apex Clean Energy awarded a $200,000 conservation grant on behalf of El Sauz and Young Wind to Bat Conservation International (BCI). BCI will work alongside Texas Parks and Wildlife and the Texas Department of Criminal Justice to restore or relocate a colony of nearly one million Mexican free-tailed bats from a critical historic bat roost in an old cotton warehouse in Huntsville, Texas. The grant will allow BCI, the Texas Department of Criminal Justice, and the Texas Parks and Wildlife Department to assess the condition of the existing roost within the warehouse and develop designs to either renovate the structure or construct a new, similar one. Additionally, the grant will be used for bat education, outreach, and research at the site and as a local economic uplift for local businesses, as visitors view the bats鈥 nightly flight emergences.

Invenergy鈥檚 Partnership with New York State Department of Environmental Conservation

At ACP member company Invenergy, a multi-year commitment to protect listed bats from predation at one of the remaining New York hibernacula is underway.听 with the New York State Department of Environmental Conservation (NYSDEC) on a mitigation project to address a risk to the state and federally protected northern long-eared bat. Raccoons were accessing a large cave where bats where hibernating, killing numerous bats each year. The Invenergy project team worked with a wildlife consultant to coordinate the trapping and removal of the raccoons at the cave entrance, which eliminated the problem of predation for not only northern long-eared bats, but also for the other bat species using the cave.

Duke Energy鈥檚 deployment of NRG System鈥檚 Bat Deterrent System
In 2019, ACP member was the first to commercially deploy NRG System鈥檚 innovative Bat Deterrent System in the continental U.S. This technology uses high frequency signals to block the echolocation, a radar of sorts, that bats use to navigate in the dark, causing them to avoid areas around wind turbines. Researchers believe the system works by preventing bats from hearing their own echolocation, making it difficult for them to hunt or socialize and causing them to leave the immediate area for more conducive spaces. The system was inspired in part by a natural defense of the , which emits its own sound to block bat echolocation.

The results of the study were largely successful, reducing bat fatalities over 54 percent for the Brazilian free-tailed bat and almost 80 percent for the Hoary bat. The latter species is a species of conservation concern that is found throughout the United States.听听


The clean energy industry supports strong collaboration and research to ensure that wind, solar and storage coexists with wildlife. Achieving a sustainable future depends on significantly expanding our nation鈥檚 clean energy supply while also protecting and conserving the environment. The work underway to successfully co-exist with bats by ACP member companies and the industry writ-large takes us one step closer toward reaching that goal.听 There鈥檚 nothing spookier than the idea of not taking the steps necessary to ensure a clean energy future for all.听
