Were the 2022 whale deaths off the US East Coast caused by offshore wind development?
The 2022 whale deaths have not been linked to offshore wind surveys or construction. Research has found no evidence of wind farms driving whale deaths, and responsibly developed wind farms avert systemic harms of fossil fuels.
Bad practices like construction during peak migration, high-speed vessels, or not monitoring whale presence can increase risk. However, established regulations such as seasonal construction limits, population monitoring, and vessel-speed rules reduce exposure. Once operating, turbine noise is significantly less disruptive than ships.
According to the NOAA, boat collisions and fishing gear entanglement account for most whale deaths, not wind turbines.
In contrast, fossil fuel drilling and burning routinely harm marine life. Oil and gas exploration uses highly disruptive sonar, oil spills kill marine animals, and emissions acidify oceans, weakening coral and shellfish. Warming causes population-level harms to marine mammals through altered migration routes and habitat loss.

About fact briefs published on Gigafact
Fact briefs are short, credibly sourced summaries that offer “yes/no” answers in response to claims found online. They rely on publicly available, often primary source data and documents. Fact briefs are created by contributors to Gigafact — a nonprofit project looking to expand participation in fact-checking and protect the democratic process.
