The Fall of Coal: Joint Impacts of Fuel Prices and Renewables on Generation and Emissions
利用美国电厂日度数据，研究天然气价格和风电对煤电发电量与排放的联合影响，发现两者交互作用显著，共同解释了2007年以来煤电下降的大部分原因。
Since 2007, US coal-fired electricity generation has declined by a stunning 25 percent. Detailed daily unit-level data is used to examine the joint impact of natural gas prices and wind generation on coal-fired generation and emissions, with a focus on the interaction between gas prices and wind. This interaction is found to be significant. Marginal responses of coal-fired generation to natural gas prices (wind) in 2013 were larger, sometimes much larger, than the counterfactual with 2008 wind generation (gas prices). Additionally, these factors jointly account for the vast majority of the observed decline in generation and emissions.
