Illinois can set example for low-carbon future

By Bernard Weinstein, The Hill's Congress Blog. 

In response to growing concerns about climate change and greenhouse gas emissions, over the past decade three-fourths of the American states have adopted renewable portfolio standards or goals (RPS) for electric power generation.  Also referred to as renewable electricity standards (RES), these policies require or encourage power providers to supply a designated minimum share of their electricity from resources such as wind, solar, geothermal or biomass.

At 25 percent by 2025, the state of Illinois has adopted one of the most ambitious renewable energy mandates in the country.
