On November 4, 2008, Missouri voters passed the Missouri Clean Energy Initiative, creating the nation’s third voter-driven state Renewable Portfolio Standard. The proposal requires that investor-owned utilities increase renewable energy generation to two percent of total output by 2011, five percent by 2014, 10 percent by 2018, and 15 percent by 2021. Two percent of generation must come from solar energy; the remainder may come from other renewable sources including landfill gas, wind, biomass, and hydroelectric power. In order to protect rate-payers, utilities are prevented from increasing prices more than one percent.

The Clean Energy Initiative ramps up the goals set forward in S.B. 54 in 2007, which calls on utilities to make a “good-faith effort” to generate 11 percent of electricity from renewable sources by 2021.
