The GHG10 case assumes a $10 per metric ton fee on CO2 emissions, beginning in the year 2015. The GHG25 assumes a $25 per metric ton fee on CO2 emissions beginning in 2015. Both cases escalate the CO2 fee at a rate of 5% per year. The GHG10 case with low natural gas prices combines the assumptions of the GHG10 case with the High Oil and Gas Resource case, which results in lower gas prices and encourages greater natural gas use. In 2012, almost 40% of total energy-related CO2 emissions resulted from electricity generation. About three-fourths of those power sector emissions occurred from burning coal, the most carbon-intensive fuel. Policies […]
