Description (excerpt):
Between 2005 and 2015, US electricity sector emissions of nitrogen oxides, which harm human health and the environment, declined by two-thirds, and many coal-fired power plants became unprofitable and retired. Intense public controversy has focused on these changes, but the literature has not identified their underlying cause. Using a new electricity sector model that accurately reproduces unit operation, emissions, and retirement, we find that electricity consumption and gas prices account for nearly all the coal plant profitability decline and resulting retirements. Nitrogen oxides regulations explain most of the emissions reductions but had little effect on coal plant profitability and retirement.
