Stanford professor Mark Jacobson wasn’t just dreaming of a world powered by renewable energy back in 2009—he was doing the math and architecting the plan. Jacobson teamed up with actor-turned-eco-hero Mark Ruffalo to co-found The Solutions Project with a mission to transition the world to 100% renewables by 2035. As Jacobson's vision took root, states and cities began making 100% renewable pledges. By 2019, his idea had reached Capitol Hill when AOC and Senator Markey introduced the Green New Deal. Jacobson’s message? We can pull it off, it’ll save us trillions, and spare millions of lives. Plus, if you’re lucky enough to live in just about any state that’s ahead of the curve, you’re already paying some of the lowest energy bills in the country.
