Measuring the Environmental Benefits of Wind Power
Joseph Cullen
American Economic Journal: Economic Policy, forthcoming
Abstract: Production subsidies for renewable energy, such as solar or wind power, are rationalized due to their perceived environmental benefits. Subsidizing these projects allows clean, renewable technologies to produce electricity that otherwise would have been produced by dirtier, fossil-fuel power plants. In this paper, I quantify the emissions offset by wind power for a large electricity grid in Texas using the randomness inherent in wind power availability. The results indicate that one MWh of wind power offsets negligible quantities of SO2, less than one lb of NOx, and less than half a ton of CO2. Only for high estimates of the social costs of pollution do I find that the value of emissions offset by wind power are greater than the renewable energy subsidies used to induce investment in wind farms.
