Chicago's 139 Fully Gas Free Buildings

These buildings are already all-electric, and feature some of the most famous buildings in the city! If even the John Hancock center or Marina Towers can run off of only electricity, your building can too.

Note: This list is of buildings that use neither natural gas nor a district steam system, since all district steam systems in the city are currently powered by burning natural gas (to the best of our knowledge).
