This Week in Cleantech is a weekly podcast covering the most impactful stories in clean energy and climate featuring Paul Gerke of Factor This and Tigercomm’s Mike Casey.

This week's episode features special guest Justin Worland at TIME Magazine, who wrote about the fires that hit Los Angeles in January 2025, and how to prevent similar disasters in the future.

This week's "Cleantecher of the Week" is Josh Silverman, the CEO of Windfall Bio, which figured out how to create microbes that consume leaking methane from cow manure lagoons as their food source. His team’s system tackles one of agriculture’s toughest climate challenges with a low-cost, farm-ready solution. Congratulations, Josh!
