Using a vast sample of data collected in a citizen science project, researchers say they’ve been able to discern how hydropeaking affects aquatic insects that form the base of river food chains. The information could help resource managers develop alternative hydropower practices that aren’t as harmful to ecosystems, according to a new study published in the journal BioScience.
Hydropeaking refers to the practice of increasing river flows at times of peak demand, generally during the day. This study shows how abrupt water level changes affect aquatic insects in every stage of life. The research was done by scientists with the U.S. Geological Survey, Oregon State University, Utah State University and Idaho State University.

Can the U.S. catch up to Europe with offshore wind power?
The U.S. is lagging far behind European countries when it comes to developing offshore wind power, but that’s starting to change.
This week, the Bureau of Ocean Energy Management took another step toward boosting ocean windpower by identifying an 8,130 acre wind area energy south of Long Island, New York, that could one day be leased for development and help generate electricity where it’s needed most — close to densely populated East Coast communities.
The U.S. solar power market grew by 17 percent in 2015, adding more than 7,200 megawatts of photovoltaics and outpacing the growth of the natural gas capacity additions for the first time ever. In all, solar supplied 29.5 percent of all new electric generating capacity in the U.S. in 2015.
States free to move ahead with energy transition plans
A federal appeals court this week rejected a last-ditch effort by fossil fuel companies to block implementation of the EPA’s Clean Power Plan, which is aimed at curbing heat-trapping pollution from power plants.
University of Delaware study identifies key policy hurdles
The U.S. has fallen way behind on developing its potentially huge offshore wind energy potential, according to University of Delaware researchers, who identified some of the obstacles in a recent study.
“As we celebrate the 10-year anniversary of the U.S. Energy Policy Act of 2005, it is disheartening to see that while land-based wind and solar have reached new heights, U.S. offshore wind has remained a missed opportunity,” the paper’s lead author, Jeremy Firestone, said in a release that summarized the study findings.

‘Policymakers are more likely to price carbon appropriately if it is cheaper to move onto a low-carbon path …’
LINZ — If government leaders want to encourage a shift to renewable energy, their polices must reflect the true price of carbon, including the hidden environmental, health and societal costs of burning coal and oil.
