Can the U.S. catch up to Europe with offshore wind power?

Staff Report

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.

Just last October, a University of Delaware study showed that the U.S. is farther from commercial-scale offshore wind deployment today than it was in 2005. Before offshore wind can be developed commercially at a large scale, the U.S. must revamp regulations, as well as tax and finance policy, the study explained. Meanwhile, Europe is generating about 8 percent of its total energy capacity from windpower. Continue reading “Feds identify possible wind energy zone near Long Island”

U.S. added 7,200 megawatts of solar power in 2015

Staff Report

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.

The solar sector grew fastest in California, North Carolina, Nevada, Massachusetts and New York, but the market continues to diversify geographically, with 13 states installing more than 100 megawatts of capacity in 2015. Continue reading “U.S. added 7,200 megawatts of solar power in 2015”

Appeals court rejects bid to block EPA Clean Power Plan

States free to move ahead with energy transition plans

Staff Report

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.

An anti-environmental coalition of states and fossil fuel companies had sought an emergency stay in federal court, but the U.S. Court of Appeals for the D.C. Circuit today denied that request, stating that the petitioners’s claims didn’t meet the legal standard for emergency court action.

Climate: Will CO2 emissions drop in 2015?

More signs that global CO2 emissions may be leveling off.

Energy shift pays off

Staff Report

There may be hope for the Earth’s climate after all.

A new report from the Global Carbon Project suggests annual global carbon dioxide emissions from fossil fuels could drop slightly in 2015, contrasting with the rapid growth in emissions before 2014. The findings emphasize the need for action to stabilize and permanently lower global CO2 emissions, the researchers concluded. Continue reading “Climate: Will CO2 emissions drop in 2015?”

Report says U.S. lags on offshore wind energy

University of Delaware study identifies key policy hurdles

Staff Report

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.

According to their paper, published in the Proceedings of the National Academy of Sciences, the U.S. is farther from commercial-scale offshore wind deployment today than it was in 2005.

“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.

The catch-22 of carbon pricing

Energy policies must reflect true price of carbon.

‘Policymakers are more likely to price carbon appropriately if it is cheaper to move onto a low-carbon path …’

Staff Report

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.

The current price of carbon is below zero, once fossil-fuel subsidies are taken into account, and that is slowing the shift toward a low-carbon future, a new paper in Nature concludes. Continue reading “The catch-22 of carbon pricing”

New modeling study shows a “slowdown” effect if too many turbines are clumped together

Staff Report

FRISCO — Wind turbine installations could some day reach a point of diminishing returns if they get too big, according to a new study that evaluated the effects of large wind farms on atmospheric flow and its implications for how much renewable energy the turbines can generate.

The researchers at the University of Kansas did their study in the context of the renewable energy boom. Wind energy accounted for 3.3 percent of electricity generation in the United States in 2011. The study was aimed at learning what happens to the wind when a larger number of wind turbines removes more and more of the energy of atmospheric motion.
