Companies brought 24.9 gigawatts of new installed land-based wind capacity online in the Asia-Pacific region last year, according to the Global Wind Energy Council. China accounted for 21.2 GW of the new capacity.
Researchers have successfully used an artificial intelligence-based system dubbed WaveletFCNN to identify patterns that indicate the presence of potentially damaging ice on turbine blades. Companies could start mitigation efforts earlier if they were aware of the presence of ice, the researches wrote in a paper.
Researchers in Hawaii are exploring wind energy, tidal and other technologies to help the state meet its 100% by 2045 goal for renewables. "We definitely think of Hawaii as a 'postcard from the future' as to how renewables will attach to the grid," says Andy Hoke, a senior engineer at the National Renewable Energy Laboratory.
Wisconsin Gov. Tony Evers will become part of the US Climate Alliance, a coalition that upholds the Paris climate accord's goal to limit greenhouse gas emissions. "Gov. Evers is showing the nation that he intends to lead on climate action, and we look forward to working with the governor on his priorities like investing in transportation infrastructure, locally produced renewable energy, and natural and working lands across the state," Executive Director Julie Cerqueira says.
A bill under consideration in Nebraska that would establish a minimum 3-mile setback distance for turbines would deter future development, residents said during a hearing in Banner County on Saturday. "Anything that can be done to ensure that wind development is not hindered, but encouraged; we need to see that happening in our area," notes Dennis Armstrong of Bushnell.
Sedgwick County, Kan., is considering new rules for wind development that would include a 1.5-mile setback distance for residential properties and 3-mile one for airports and some other buildings. NextEra Energy wants to build a wind farm in nearby Reno County and may be considering one in Sedgwick.
The Environmental Protection Agency has published its action plan for per- and polyfluoroalkyl substances and says it will propose maximum contaminant levels for PFAS in drinking water by the year's end.
The Nuclear Regulatory Commission cited the Pilgrim nuclear plant for a violation in the fourth quarter related to maintenance of its feedwater system. "They've taken corrective actions and they are going to do their best to make sure that not only are the procedures more clearly [articulated], but also that management oversight has increased," said NRC spokesman Neil Sheehan.
The Tennessee Valley Authority released its draft long-term plan for power generation last week. The plan shows the utility won't pursue any new full-scale nuclear plants, but it opens the door for boosting resiliency through the use of small modular nuclear reactors.
The final plan to lower South Carolina Electric & Gas customers' rates instead of paying out initially promised $1,000 rebate checks will benefit customers in the long run, says Dominion Energy spokesperson Rhonda Maree O'Banion. No meaningful effort has been mounted by lawmakers to revise the merger terms to reinstate Dominion's rebate check payments.
