Chicago Mayor Rahm Emanuel, along with other top city officials, has announced the city’s intention to power every one of its public buildings with 100% renewable energy by 2025. This would make Chicago the largest city in the U.S. to power its properties with renewable energy. The announcement comes in direct opposition to recent policy proposals put forward by the Trump administration.

“As the Trump administration pulls back on building a clean energy economy, Chicago is doubling down,” Mayor Emanuel said. “By committing the energy used to power our public buildings to wind and solar energy, we are sending a clear signal that we remain committed to building a 21st-century economy here in Chicago.”

The announcement was made atop the roof of the Shedd Aquarium, which is not a public building, but recently installed 900 solar panels. The Shedd is participating in the mayors Retrofit Chicago Energy Challenge, which also involves installing high-efficiency lighting and large on-site batteries.

The combined energy use of the city’s buildings in 2016 was approximately 1.8 billion kilowatt-hours, which accounts for about 8% of the city’s total electricity use. This is also the equivalent of powering about 295,000 Chicago homes for the same amount of time. In recent years, the city has made significant moves towards its renewable energy goals by eliminating coal use from over one billion kilowatt hours in 2013 alone. The city also reduced its carbon emissions by 7% between 2010 and 2015. Chicago was also named the 2017 ENERGY STAR Partner of the Year Award winner by the U.S. Environmental Protection Agency.

“Today’s action is a historic step forward in establishing Chicago as a clean energy leader,” said Jack Darin, Illinois Sierra Club President. “By moving boldly to repower its public buildings with renewable energy like wind and solar, Chicago is leading by example at a time when local leadership is more important than ever. While President Trump and his administration would reverse America’s progress on climate change and clean energy, Mayor Emanuel is ensuring that Chicago will move forward, and that its residents will benefit from the good jobs and cleaner air that come from renewable energy projects. We look forward to working with the Mayor, community leaders, and the people of Chicago to achieve this bold goal on the path to eventually powering all of Chicago with 100% clean energy.”
