Will Russia’s War In Ukraine Finally Spur A Clean Energy Revolution?

This week President Biden tightened sanctions on Russia, cutting off imports of Russian oil to the United States in response to Russia’s war on Ukraine. The conflict has put a sudden, sharp pressure on an already strained energy system, causing uncertainty—and rising prices.

However, in a recent Quinnipiac poll, 71% of Americans said they favored cutting off Russian oil imports, even if it resulted in higher prices at the pump. And the German Economic Ministry announced plans to speed up wind and solar projects as it seeks to lessen its dependence on Russian energy.

Ira talks with Dan Esty, Hillhouse Professor at Yale University, director of the Yale Center for Environmental Law and Policy, and co-director of the Yale Initiative on Sustainable Finance, about whether the Ukraine conflict might hasten a worldwide shift to greener energy sources. They discuss the role that pressure from commercial entities and investors might have on long-term climate policy.

Searching For Life On The Red Planet Prompts Deeper Questions

As rovers like Perseverance and Curiosity roam the surface of Mars in search of signs of past life, SciFri producer Christie Taylor asks scientists and science-fiction podcasters Mike Wong and Moiya McTie, “How do you define ‘life’ anyway?”

Plus, how to find habitable exoplanets, the case for Europa as a source of more interesting organisms than Mars, and why Star Trek’s hive mind alien, the Borg, is a good example of an alternate way of being alive.

Where Does Toilet Water Go?

Many of us have morning routines that use a lot of water. After the alarm goes off, folks may stumble to the kitchen for a glass of water, then head to the bathroom to use the toilet, brush teeth, and take a shower. That very normal part of many people’s mornings is water-intensive. And where does that all go?

For many Americans, it’s a given that when we do dishes or wash our hands, that water is out of sight, out of mind—we don’t have to think about it again. But wastewater and sewage systems are complex and essential networks to our daily lives. And when they don’t work as we expect, whether that’s due to flooding or aged infrastructure, it’s a major problem.

There’s a whole community of engineers and scientists devoted to improving our wastewater and sewage systems to reflect our changing planet. More people living in cities, and increased rain from climate change are two recent examples of major adjustments that our systems weren’t built to handle. But researchers are now leading projects like New York’s Flood Sense, which alerts residents to sewage exposure, while SARS-CoV-2 detection in city wastewater has demonstrated the importance of monitoring these systems.

Joining Ira to talk about the importance of sewer science is Andrea Silverman, assistant professor of environmental engineering at the NYU Tandon School of Engineering.
