Emissions Savings from Wind Power Generation in Texas

Abstract:
Wind power has the potential to reduce emissions associated with conventional electricity generation. Using detailed, systemic hourly data of wind generation and emissions from plants in ERCOT (Texas), we empirically estimate the SO2,NOx and CO2 emissions offset by wind generation. Our estimation strategy implicitly captures both the marginal unit of generation displaced by wind on the electrical grid, and the marginal emissions reduction from that displaced unit. Our results also reveal substantial variation in emissions reductions, which appear to be strongly driven by differences in the generation mix. The environmental benefits from emissions reductions in ERCOT fail to cover government subsidies for wind generation.



Natural Gas and U.S. Economic Activity

Year: 2014
Volume: Volume 35

Abstract:
Previous empirical work has shown that real natural gas prices have a negligible impact on total U.S. industrial production and most of its sub-indices. We reassess these conclusions using a multivariate framework and a time-frame that includes recent developments in the U.S. natural gas market. Our results show that natural gas does affect U.S. economic activity, primarily through changes in its production. The shale gas revolution has changed this relationship - a one percentage point increase in natural gas supply raises total U.S. industrial production by more after 2008 than before.
