Obtaining electricity through manure avoids GHG emissions associated with fossil energy sources. In 2019, 42% of the electricity in Wisconsin was produced from coal (most of this was imported from other states) . The U.S. Energy Information Administration estimates that for every kilowatt of electricity generated from coal, 2.21 pounds of CO 2 are emitted . Though obtained from renewable sources, bioenergy is similar in many respects to natural gas. Assuming bioenergy has a comparable rate of emissions to natural gas (0.41 tonne of CO 2 /MWh) there is a net emissions savings of 0.59 tonne/MWh compared to coal. In the case where our 245 CAFOs process 100% of their manure for electricity (1.42% of annual state demand) this avoids 5.26×10 5 tonnes of CO 2 . At the current SCC, this represents annual social savings of 26.8 million USD.
