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 episode features special guest Jennifer Hiller from The Wall Street Journal, who wrote about utilities' fears that overbuilding for planned data centers could increase rates for consumers if the projected demand does not materialize.

This week's "Cleantecher of the Week" is Paul Riley, CEO of Lululemon-backed recycling startup Samsara Eco. The company’s technology uses AI to break down tough-to-recycle materials with enzymes, allowing the waste to be converted into resins and made into new products. Congratulations, Paul!
