For more than 20 years, Adam Browning was solar's biggest cheerleader.

There was 165 MW of interconnected solar in the U.S. in 2002 when Browning founded Vote Solar. The organization quickly evolved into the industry's preeminent advocacy group. When he stepped down as executive director in 2021, that figure stood at 122 GW.

Today, Browning has his sights set on the next big decarbonization story, using lessons learned from solar's twists and turns to take on a "biblical" challenge.

Browning, now the executive vice president of policy and communications for the startup Forum Mobility, looks back on his storied career leading Vote Solar, reacts to the controversial NEM 3.0 ruling in California, and shares why he's starting over to take on fleet electrification.

That's all next on Factor This!
