Weighing The Risks Of Solar Geoengineering

Guest

Special Crossover Episode with Catalyst

This week, Columbia Energy Exchange brings you an episode of another podcast called Catalyst. 

It’s a weekly show hosted by climate tech veteran Shayle Kann about the future of decarbonization. Each week, different experts, researchers, and executives come on to unpack the latest hurdles to decarbonization and advancing new climate tech solutions. 

This episode is all about weighing the risks and rewards of solar geoengineering. 

In it, Shayle speaks with a climate modeler named Dan Visioni who conducts research on solar geoengineering at Cornell University’s Sibley School of Mechanical and Aerospace Engineering. 

They explore key questions, including:

  • What do we know about the potential effects on ozone, precipitation and ecosystems? What do we need to research, and what could we learn by testing?
  • Which could scale faster: carbon dioxide removal or solar geoengineering?  
  • Solar geoengineering could cost a tiny fraction of the amount required to scale up carbon dioxide removal. Does that mean it could buy us time to draw down emissions in a less expensive manner? Or would its relative affordability enable a rogue actor to deploy it without international collaboration?
  • And who gets to make the final decision on whether the world should deploy solar geoengineering? Whose hand is on the thermostat, so to speak?

Episodes of Catalyst drop every Thursday. The show is a co-production of Post Script Media and Canary Media.

Trends and 2025 Insights on the Rise of Electric Vehicles in the USA

Plug-in electric vehicles (EVs) are reshaping the transportation energy landscape, providing a practical alternative to petroleum fuels for a growing number of applications. EV sales grew 55× in the past decade (2014–2024) and 6× since 2020, driven by technological progress enabled by policies to reduce transportation emissions as well as industrial plans motivated by strategic value of EVs for global competitiveness, jobs and geopolitics. In 2024, 22% of passenger cars sold globally were EVs and opportunities for EVs beyond on-road applications are growing, including solutions to electrify off-road vehicles, maritime and aviation. This Review updates and expands our 2020 assessment of the scientific literature and describes the current status and future projections of EV markets, charging infrastructures, vehicle–grid integration and supply chains in the USA. EV is the lowest-emission motorized on-road transportation option, with life-cycle emissions decreasing as electricity emissions continue to decrease. Charging infrastructure grew in line with EV adoption but providing ubiquitous reliable and convenient charging remains a challenge. EVs are reducing electricity costs in several US markets and coordinated EV charging can improve grid resilience and reduce electricity costs for all consumers. The current trajectory of technology improvement and industrial investments points to continued acceleration of EVs. Electric vehicles are increasingly adopted in the USA, with concurrent expansion of charging infrastructure and electricity demand. This Review details these trends and discusses their drivers and broader implications.
