NETL sets forth a vision of 36% based on retirements of low efficiency units, and improvements
within the best-in-class. Under a scenario where generation from coal is constant at the 2008
level, increasing the average efficiency from 32.5% to 36% reduces U.S. GHG by 175
MMmt/year or 2.5% of total U.S. GHG emissions in 2008.
