Low-Carbon Electricity Pathways for the U.S. and the South: An Assessment of Costs and Options

This paper uses the National Energy Modeling System to evaluate alternative low-carbon electricity pathways. The authors find that the least-cost compliance pathway involves a combination of renewable and energy efficiency policies, plus a modest price on carbon that could be expected to result from the Clean Power Plan’s implementation. This pathway also produces substantial benefits including lower electricity bills, greater GDP growth, and significant reductions in SO2, NOx, and mercury emissions.
