To support his claim Mr. Campbell cites a debunked fossil fuel industry attack on wind and actually misreports the findings of that report. Even this report, paid for by a fossil fuel lobbying group and conducted by a fossil fuel company, found that wind energy drastically reduces pollution. All utility and grid operator data and peer-reviewed studies on the subject confirm that finding, concluding that wind energy has no negative impact on the efficiency of fossil-fired power plants. In fact, wind energy's pollution reductions are often larger than expected because wind energy displaces the most expensive, and therefore least efficient, fossil-fired power plants first. The reality is that wind energy is easier and cheaper for grid operators to accommodate than large fossil and nuclear power plants, as wind energy output changes gradually and predictably while conventional power plants break down frequently and abruptly.
