Are Any U.S Cities Running Completely on Green Energy?

Several small-to-medium American cities, such as Burlington, Vermont, and Aspen, Colorado, have successfully transitioned to 100% renewable electricity on an annual basis. These communities utilize a combination of wind, solar, hydroelectricity, and biomass to meet their power needs, often verified through renewable energy credits and long-term contracts. While these achievements represent significant milestones in decarbonization, the episode clarifies that "green energy" status currently applies only to the electrical grid rather than total energy consumption. Most residents in these areas still rely on fossil fuels for transportation, aviation, and heating systems. Consequently, these pioneering municipalities serve as scalable models for clean energy procurement, even as they face ongoing challenges regarding grid reliability and the need for broader electrification.
