Key Takeaways
- Chicago has transitioned to 100% renewable energy for all municipal buildings as of January 1, 2025.
- The city’s renewable energy primarily comes from the Double Black Diamond solar farm, the largest east of the Mississippi, providing 70% of its energy needs.
- This shift is estimated to reduce carbon emissions by nearly 300,000 metric tons, while also supporting clean energy job training initiatives.
Chicago Achieves 100% Renewable Energy for Municipal Buildings
As of January 1, 2025, Chicago is powered entirely by renewable energy in all municipal buildings, including its two major airports, O’Hare and Midway. This achievement follows nearly a decade of planning and development, culminating in the completion of the Double Black Diamond solar farm in central Illinois. Spanning approximately 4,000 acres, this solar array has a capacity of 593 MW and is now the largest solar farm east of the Mississippi.
Chicago will source about 70% of its energy for municipal operations from this solar farm. The remaining 30% will be covered through renewable energy credits (RECs), which will give the city time to explore additional renewable energy methods, such as rooftop solar installations. According to Jared Policicchio, the deputy chief sustainability officer, this approach allows flexibility while transitioning to full renewable energy.
The city’s commitment to renewable energy is expected to significantly impact its carbon footprint, reducing greenhouse gas emissions by an estimated 300,000 metric tons annually. Additionally, Chicago has invested $400,000 into a deal for clean energy job training, further reinforcing its commitment to sustainable energy initiatives.
With these developments, Chicago sets an example for urban centers aiming to achieve sustainable energy goals while also promoting economic growth through job training programs in the green energy sector.
