Electricity-sector CO2 emissions in 2030 under “business-as-usual”: These depend on two parameters — electricity sales (which determine) generation; and the CO2 “content” of an average kWh generated. I estimated future electricity sales using AEO (that’s the US Energy Information Administration’s Annual Energy Outlook) forecasts of GDP growth and electricity rates, which I processed through assumed elasticities of 0.5 for income and (negative) 0.7 for price. For CO2 content, I assumed an annual decline in CO2/kWh of 1.0%, which is half of the average 2.0% “decarbonization” rate experienced in 2005-2013. As noted or implied above, U.S. electricity-sector emissions were 2414 million tonnes of CO2 in 2005 and 2053 million in 2013. A 30% cut in the former figure (the President’s goal) is 724 million tonnes, implying a 2030 target of 2414 less 724, or 1690 million tonnes. My modeling implies business-as-usual year-2030 emissions of 2045 million tonnes (coincidentally, almost identical to actual 2013 emissions). Reducing that to 1690 million tonnes requires a relative cut of 355 million tonnes, which is just 6.7% of actual year-2013 total U.S. emissions of 5313 million tonnes.

Dr. E. Melanie Dupuis
Inspired by new scientific studies of the human body as a metabiome, Dr. E. Melanie Dupuis, Professor and chair, Department of Environmental Science and Studies, reimagines the American body politic through a new metaphor — digestion — opening social transformations to ideas of mixing, fermentation, and collaboration. In doing so, she explores how social activists can rethink politics as inclusive processes that involve the inherently risky mixing of cultures, standpoints, and ideas. Dangerous Digestion at Amazon.
