Zero emission wind energy also provides states with valuable flexibility for finding the optimal energy mix, relative to low-carbon energy sources that have some emissions. For example, because a MWh of gas generation emits nearly half as much CO2 as a MWh of coal generation, nearly twice as many MWh of coal generation must be displaced to achieve the same level of emissions reductions versus if a zero-emission compliance option were used instead
