St. Louis, MO – More than 25 states require that a portion of electricity comes from renewable sources, like wind, solar, biomass, and water.
On election day, Missouri voters will decide whether their state should have such a requirement too.
If Proposition C passes, the state's largest utilities will have to get at least 15 percent of their electricity from renewable resources by 2021.
As KWMU's Maria Hickey reports, supporters based the measure on a similar referendum in Colorado.
