Chicago commits to 100% renewable power for all city buildings

The City of Chicago has committed to power all city properties with renewable energy by 2025.

The pledge makes Chicago the largest U.S. city to implement a clean energy policy for all of its public buildings. Mayor Rahm Emanuel’s Office said that the commitment would be met by multiple means, including on-site generation and the acquisition of renewable energy credits.

“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,” Emanuel said.

The president of Illinois’s Sierra Club hailed the move as an example of badly needed local leadership on clean energy.
