In the United States, the removal of dams now outpaces the construction of new ones—with more than 1,400 dams decommissioned since the 1970s—and a new study (link is external) suggests that the ecosystem effects of dam removal can be predicted.

Fossil fuel combustion is the main contributor to black carbon collected at five sites around the Arctic, which has implications for global warming, according to a study by an international group of scientists that included a team from Baylor University.

Coal-fired power plants produce more than just the carbon dioxide that contributes to global warming. 

Los Angeles is abandoning its $5 billion plan to rebuild three aging natural gas-fired power plants, deciding instead to phase out the plants and invest in renewable energy, Reuters reported.

A set of technologies that is expected to have its first results four years from now is designed to resolve one of the world’s greatest oil and gas exploration challenges today: carbon dioxide (CO2) and methane (CH4) emission in the atmosphere. 

More than 2.4 million miles of energy pipelines crisscross the United States. If assembled end-to-end, they would circle the Earth almost 100 times!

Recovery of vegetation on plugged and abandoned oil and gas well sites on the Colorado Plateau is influenced by time, moisture, nonnative plants and the type of plant community that was originally in place before well sites were constructed, according to a recently published study by the U.S. Geological Survey.

Scientists have created flags that can generate electrical energy using wind and solar power.

Green plants capture light that spans the visible solar spectrum, and while a broad spectral range is required for sufficient absorption, the process requires energy to be funneled rapidly and efficiently downhill to drive charge separation and water splitting.

Perovskites — a broad category of compounds that share a certain crystal structure — have attracted a great deal of attention as potential new solar-cell materials because of their low cost, flexibility, and relatively easy manufacturing process.
