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 Christopher Mims from The Wall Street Journal, who wrote about how several startups are bringing solar-powered vehicles closer to reality.

This week's "Cleantecher of the Week" is Ramón Méndez Galain, Uruguay’s energy secretary. Under his leadership, the country went from relying heavily on fossil fuels to establishing a stable grid powered almost entirely by renewable sources. Within just five years after he took over, renewables powered 98% of the country. Congratulations, Ramón!
