Interest is booming in renewable energy sources, especially in the areas of wind, solar, and biofuels. Such energy sources have huge benefits, including diversification of the nation’s energy portfolio, new jobs, and potential reductions in greenhouse gas emissions. Yet these energy sources sometimes have adverse effects on ecosystems and the wildlife that live in them, such as bats, birds, and reptiles and amphibians.
Yet as our nation’s energy portfolio continues to grow in these areas, it is critical that development be guided by the best science available so that it happens in the right way and the right places.
USGS is in a unique position to provide that science, bringing together many fields of research to help managers, policymakers, industry, and others make decisions that allow for energy growth while responsibly lessening conflicts between renewable energy, ecosystems and wildlife. We bring new focus not only by using large-scale landscape or regional approaches for evaluating potential impacts to species and habitats, but also by unraveling the effects on the “small” scale, such as how and why a bat interacts with the blades of a wind turbine at night and whether solar panels block a migration path between feeding and breeding areas.
Our country’s know-how and ingenuity – combined with science – can help the United States grow a responsible, sustainable, and diversified energy future. |

Duck! Long-Tail Ducks Avoid Cape Wind Energy Project: Satellite tracking of long-tail ducks over three wintering seasons confirms that while they use the Nantucket Sound regularly in their daily movements, they did not use the area proposed for the Cape Wind Energy Project as a roosting site during the time frame of the study.
The U.S. Geological Survey research looked at one of the world’s largest populations of long-tail ducks and found that hundreds of thousands of these elusive birds engage in a bizarre 30-50 mile morning commute from Nantucket Sound to the Atlantic Ocean, returning each evening.
