ELPC plays a critical role advancing environmental solutions in Illinois, based out of our headquarters in Chicago. From elected officials to the courts to the state’s key commissions, boards, and agencies, we know Illinois’ leaders and we know how to get things done. ELPC is accelerating renewable energy, retiring polluting coal plants, improving transportation, safeguarding clean water and air, and protecting wild places like the Savanna Sand Prairie and the Shawnee National Forest.

Illinois is the economic capital of the Midwest, as a hub of business, media, and transportation. With the region’s largest population center in Chicago, Illinois is also the highest energy user in the Midwest, but today our electricity is increasingly renewable. ELPC policy advocates have helped Illinois become the nation’s sixth leading state for wind power, with over 5,000 megawatts of installed capacity.
