Warming Up to Solar Energy in Chicago, Cook County
April 11, 2017

Community solar is ready to move forward in Chicago and Cook County.
When Chicagoans drive toward Des Moines, Indianapolis and Springfield, they see local wind turbines helping to power our transition to a clean energy future. Here in Cook County, our best renewable energy growth opportunity is installing modern solar energy panels on residential and commercial building rooftops and on underutilized “brownfield” industrial sites.
Solar energy development is being driven by smart policies, technological improvements, and civic and political leadership. The Illinois Legislature passed a modernized Renewable Portfolio Standard, which, if implemented well, can jump-start solar energy installations and financing. It’s especially important for Illinois to move quickly to leverage the federal Investment Tax Credit for solar energy that is available over the next four years.
There have been huge technological innovations in almost all solar energy equipment. Solar panel costs have dropped from $4 per watt to less than 40 cents per watt over the past 10 years, and solar inverter efficiency has improved to close to 99 percent.
Since 2015, Cook County has partnered with the city of Chicago, Environmental Law & Policy Center, Elevate Energy, Commonwealth Edison and West Monroe Partners to advance development of new community solar projects. In 2011 the City of Chicago solar formed an energy partnership with the Illinois Institute of Technology, Environmental Law & Policy Center and West Monroe Partners. Both SunShot initiatives, supported by U.S. Department of Energy grants, accelerate solar energy projects, streamline processes and remove barriers.
