Someday, U.S. electrical power generation may come from 100% renewable energy consisting almost entirely of wind and solar. But predictions of that happening within 10 or 20 years are unrealistic. There are simply too many obstacles standing in the way, among them: the massive investment of capital that would be required, the disruption of entire industries, technical challenges, and considerable societal and environmental impacts.
Congressional Democrats today unveil a “Climate Crisis Action Plan” similar to the Green New Deal proposed by Rep. Alexandria Ocasio-Cortez last year, which sounded like a dream to many progressives and climate activists.
At the heart of the proposal are billions in new subsidies and a federal mandate to achieve 100% renewables.
As states grapple with the need to reduce carbon emissions, widespread retrofitting of industrial facilities and powerplants with capture and storage technology remains an elusive goal and emerging challenge in the U.S.
Almost every international climate change scenario under the 2015 Paris Agreement shows the need for an enormous ramp-up of carbon capture, utilization and storage (CCUS) technologies to meet global goals. Timing matters, not just scale.
There’s an old saw in the trash business that says, “everybody wants their trash picked up but nobody wants it put down.”
That’s not a perfect analogy for what’s happening with renewable-energy projects in New York and New England but the sentiment behind it is familiar.
Capturing carbon dioxide from the fossil-fuel industry is key to slowing dangerous global warming, energy chiefs said in Davos as climate concerns dominated the annual business forum more than ever before.
Oil and gas producers are under mounting pressure to help prevent a damaging rise in temperatures, and carbon capture is increasingly luring investors as a tool to curb emissions.
A greenhouse gas that can cause 12,000 times more warming per tonne than carbon dioxide is rising unexpectedly in the atmosphere, despite reports by its major producers, China and India, that they've mostly eliminated emissions of the gas.
Atmospheric gas measurements at five stations around the world show that emissions of HFC-23 or trifluoromethane reached a record high in 2018 of 15,900 tonnes, reports a study led by Kieran Stanley, a visiting research fellow at the University of Bristol.
