This Week in Cleantech is a weekly podcast covering the most impactful stories in clean energy and climate in 15 minutes or less featuring Paul Gerke of Factor This and Tigercomm’s Mike Casey.

This week's "Cleantecher of the Week" is Tom Steyer, Co-Executive Chair of Galvanize. He reminds us that when we talk about climate now, the conversation is about technology, costs, and politics, which is important. However, we cannot lose sight of what this is truly about: passing on a livable planet. Tom reminds us about this after a weekend camping with his grandkids. Congratulations Tom!
