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 Molly Taft from WIRED, who discusses Elon Musk's AI company xAI's decision to add 19 natural gas turbines to its Colossus 2 data center in Southaven, Mississippi.

This week’s “Cleantecher of the Week” is fourth grader Christian Mango. At 10 years old, Christian researched electric vehicles, cited facts, and wrote to his U.S. congresswoman Virginia Foxx proposing a $5,000 federal EV tax rebate. When she responded by reprimanding Christian as foolish and his teachers as propagandists, Christian made national news for writing the letter. Congratulations Christian!
