How Climate-Induced Risks Affect Power System Planning In The U S Southeast

Password Remember me New to Energy Central? Applying for membership with Energy Central allows you to connect with a network of more than 200,000 global power industry professionals. Typically, climate change risks to electric power supply and demand are investigated separately. A new study led by Fonseca in  Environmental Science & Technology takes on both. In so doing, the study highlights opportunities for how long-term energy planning might include a more comprehensive assessment of climate change impacts, and how adaptation and mitigation strategies can converge. In this study, Fonseca and 10 co-authors evaluate planning for capacity expansion in the U.S. Southeast in 2050. They use a series of models to explore energy mixes that include coal, hydropower, nuclear, solar, natural gas, and wind in the future relative to today. Their multi-model framework captures climate change impacts of an ensemble of future climate change projections. The suite of simulation models

The Arctic Is Now Leaking Out High Concentrations of Forever Chemicals

The Arctic Is Now Leaking Out High Concentrations of Forever Chemicals 29 JULY 2021 Polyfluoroalkyl and perfluoroalkyl substances (PFAS) are known as forever chemicals because they don t naturally break down in the environment. Now a new study reveals the increasing pace of Arctic ice melt is leaking more of these chemicals into the environment.   PFAS don t originate in the Arctic, but they do settle there – they re used in all kinds of human-made products and processes, from pizza boxes to foam used to fight fires. Once released into the atmosphere, they re often trapped in Arctic ice floes. This is nothing new. But in a worrying new study by chemists from Lancaster University in the UK, it appears the concentrations of PFAS in bulk sea ice are closely related to the salinity of the water. So the more briny the sea, the more concentrated these forever chemicals get.
