In 2001, a team of engineers at a then-obscure R&D company called AC Propulsion quietly began a groundbreaking experiment. They wanted to see whether an electric vehicle could feed electricity back to the grid. The company’s president, Tom Gage , dubbed the system “vehicle to grid” or V2G. In the boom of the 1920s, U.S.

Among the most articulate and almost certainly the wonkiest is Jesse Jenkins , a professor of engineering at Princeton University, where he heads the ZERO Lab—the Zero-carbon Energy systems Research and Optimization Laboratory, that is. How fast can you ramp your power plants up and down to handle the variability from wind and solar?
