Airborne Emission & High Level Nuclear Waste Comparison 
Type of Emission Total ESE system avg in lbs per MWh Regional average in lbs per MWh
Sulfur Dioxide 4.9 12.4
Carbon Dioxide 1,271.20 2,088.10
Oxides of Nitrogen 2 5
High-Level Nuclear Waste 0.0034 0.0074
These rates show the relative amount of air emissions or nuclear waste in pounds per megawatthour (MWh) produced as a result of generating electricity from fossil fuel or nuclear units. The emission and nuclear waste characteristics of the electricity you receive vary depending on the mix of fuels used in generating the electricity provided by your electric supplier. The regional average includes data from Michigan, Illinois, Indiana, Ohio, and Wisconsin. Nuclear waste is a solid waste product that is stored on site. It is not an emission and is not released into the environment.
