Chicago keeps its New Year’s resolution: All city buildings now use 100% clean power

It takes approximately 700,000 megawatt hours of electricity to power Chicago’s more than 400 municipal buildings every year. As of January 1, every single one of them — including 98 fire stations, two international airports, and two of the largest water treatment plants on the planet — is running on renewable energy, thanks largely to Illinois’ newest and largest solar farm.

The move is projected to cut the carbon footprint of the country’s third-largest city by approximately 290,000 metric tons of carbon dioxide each year — the equivalent of taking 62,000 cars off the road, according to the city.
