USGS researchers used a small-scale commercial windmill as an essential part of its new device to measure snowfall in remote areas.

Scientists have found that wind turbines are causing fatalities of certain species of migratory insect-eating bats, although a March 2011 study in Science suggests that solutions to reduce the impacts of wind turbines on bats may be possible.

A drill rig at the Mount Elbert test site in Alaska's North Slope, just west of Prudhoe Bay. USGS joined BP Exploration (Alaska) and the U.S. Department of Energy to drill a test well to study natural gas production from gas hydrate deposits. Read more about the Mt.

Brown's Gulch is below the Brooklyn Mine, a few miles north of Siverton, Colorado, in the Mineral Creek basin.

This image shows an inukshuk, a stone cairn used by indigenous peoples in northern latitudes, particularly in places like northern Canada. 

During Ocean Drilling Program Leg 204, nine sites were cored and wireline logged on the Oregon continental margin to determine the distribution and concentration of gas hydrates in an accretionary ridge setting, investigate the mechanisms that transport methane and other gases into the gas hydrate stability zone, and obtain constraints on physical properties of

A drill rig at the Mallik test site in Canada's Mckenzie Delta.  USGS joined the Geological Survey of Canada, JAPEX, and the Japanese National Oil Company to drill test wells for natural gas production from gas hydrate deposits.
