Supporters of the Green New Deal (GND) draw inspiration from the federal government’s bold experiments of the 1930s. But there’s one progressive model from that era still standing — and thriving — which goes virtually unmentioned by today’s GND activists: the Tennessee Valley Authority (TVA).

Today, the TVA still generates electricity for 10 million people across seven states. And the municipal power company of Chattanooga, Tennessee today operates the country’s most successful and advanced public fiber internet service thanks to the TVA’s 1939 acquisition of the state’s for-profit utility company TEPCO.

That should all sound familiar to supporters of Bernie Sanders, Alexandria Ocasio-Cortez, and the Green New Deal. The TVA is, in fact, our best example of public power — and it’s already here. Bernie’s Green New Deal plan even sought to expand the TVA and create more institutions like it, giving them a mandate to build even cleaner electricity generators and nationwide high-speed internet service.
