Even Smart People Are Still Arguing About Fossil-Free Electricityby 3p Contributor on Friday, Jul 21st, 2017 CLIMATE & ENVIRONMENTSHAREClick to share on Twitter (Opens in new window)25Click to share on Facebook (Opens in new window)2556Click to share on LinkedIn (Opens in new window)56Click to share on Google+ (Opens in new window)Click to email this to a friend (Opens in new window)Click to print (Opens in new window)U.S. cities like Chicago have pledged to continue working toward the Paris Agreement on Climate Change. By Felix Kramer and Rosana FrancescatoAt a pivotal moment for climate strategies, scientists and business leaders have started a public debate about how fast and how fully we can leave oil, coal, and gas behind. More people now recognize climate change as the pre-eminent issue of our time, a core focus of resistance, and a source of massive economic opportunities.Imagine looking back and saying, “The Anthropocene Epoch started dangerously, as human activity threatened our future. But that sparked an unprecedented transition that protected our air and water. Every country pulled together to ensure a livable world. Our confidence, ingenuity, and resolve made it humanity’s greatest triumph.”After the U.S. government walked away from its international climate commitments, other key players including companies, cities, and states – where much of the action was already taking place – upped the ante. Policies, legislation, and entrepreneurship increasingly reflect this urgency. Globally, cities and companies are setting timetables to get off fossil fuels. Some are already there! Roadmaps created by Stanford engineer/atmospheric scientist Mark Z. Jacobson and the Solutions Project he co-founded helped make “100 percent renewables by 2050” a meme.But some have privately questioned the goal’s assumptions, research, and feasibility. Now 21 prominent climate scientists have issued a comprehensive public critique in the same Proceedings of the National Academy of Sciences where Jacobson published in 2015. Jacobson’s team gave broad and line-by-line responses, to which the critics responded.This debate highlights the views of experts who support renewables, but believe the electric grid needs a “many of the above” portfolio. To keep the lights on, they say we may long need 20 percent low- or zero-carbon non-renewable baseload capacity. They favor keeping open most atomic plants. They support efforts to develop affordable next-generation nuclear, CCS (carbon capture & sequestration), hot fusion, and LENR (low energy nuclear reactions). They hope these can be deployed at scale in time to make a difference.
