The Big Interview: John Arnold

If you work around climate or clean energy, you probably know about John Arnold. Although he began his career as a natural gas trader, Arnold has since become one of the country’s most important clean energy investors. He’s the chairman of Grid United, a transmission development firm undertaking some of the country’s most ambitious power line projects, and he is an investor in the advanced geothermal startup Fervo. He and his wife Laura run the philanthropic organization Arnold Ventures.

On this week’s episode of Shift Key, Rob talks with Arnold about the current energy chaos and what might come next. They discuss Arnold’s first trip to China, whether Congress might pass permitting reform this year, and what clean energy companies should learn from the fossil fuel industry. 

Shift Key is hosted by Robinson Meyer, the founding executive editor of Heatmap News.
