The Impact and Cost-Effectiveness of the Missouri Solar Rebate Erin Noble Nicholas School of the Environment Duke University Advisor: Randy Kramer
Evaluating the Missouri Solar Rebate: Scope and Objectives Growth Cost-Effectiveness Economic, Environmental and Public Health Impact
Solar Industry Overview
Reason for Rapid Expansion #1: Decreasing Price of Solar
Solar Industry Overview Reason for Rapid Expansion #2: Higher Electric Rates
2008 Prop C: Missouri Clean Energy Initiative $2 15% by 2021 RES $2/watt solar rebate Applies to Missouri’s three Investor-owned Utilities Ameren Missouri (St. Louis) Kansas City Power and Light (KCPL) Empire Electric (Springfield). Not offering the rebate – Challenged in court.
Part 1: Growth Method In-state comparison Empire vs. Ameren vs. Kansas City Power and Light Out-of-state comparison Missouri vs. Kentucky vs. Nebraska
Comparison: In-state Growth
Comparison: Out-of-state Growth
Part 2: Cost-Effectiveness Method Solar rebate vs. new generation U.S. Energy Information Administration The high cost of peak power Solar helps decrease expenditures on expensive peak power

Cleaner Air, Healthier Families: Solar Rebate Reduces Fossil Fuel Emissions Average Missouri home uses lbs. of coal a day. 1 kilowatt hour of power = 1 pound of coal
Cleaner Air, Healthier Families: Decrease air emissions and reduce fatalities Coal plant emissions Mercury: neurological disorders in children 55,000 premature deaths a year Asthma and lung disease.
