Wind Integration vs. Air Emission Reductions: A Primer for Policymakers

By Mary Hutzler -- June 24, 2010

Many claim that wind generation is beneficial because it reduces pollution emissions and does not emit carbon dioxide.  This isn’t necessarily the case. The following article explains a phenomena called cycling where the introduction of wind power into a generation system that uses carbon technologies to back-up the wind  actually reduces the energy efficiency of the carbon technologies. Recent studies  with actual data have estimated the impact of cycling on air pollution and carbon dioxide emissions.

Energy modelers evaluating the impact of legislation such as Senator Bingaman’s American Clean Energy Leadership Act and the American Power Act proposed by Senators Kerry and Lieberman should take note for their models most likely are underestimating the cost of compliance by incorrectly modeling the integration of wind power into the electricity grid.

Wind is not a new technology.…
