A carbon dioxide (CO₂) injection well drilled by the Southeast Regional Carbon Sequestration Partnership (sponsored by the U.S. Department of Energy) at the Cranfield CO₂ test site in Mississippi. The well was drilled to test the effectiveness of injecting and storing CO₂ in a deep saline reservoir.

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.

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
