Wind energy is the environmentalists’ great energy hope, but two inconvenient truths seem to come between fantasy and reality.
1. Study after study shows that wherever wind development was put in place, natural gas demand went up and the environmental benefits were the opposite of what the advocates expected.
“Cycling” coal plants to accommodate wind generation makes the plants operate inefficiently, which drives up emissions. Moreover, when they are not operated consistently at their designed temperatures, the variability causes problems with the way they interact with their associated emission control technologies, frequently causing erratic emission behavior that can last for several hours before control is regained. Ironically, using wind to a degree that forces utilities to temporarily reduce their coal generation results in greater SO2, NOX and CO2 than would have occurred if less wind energy was generated and coal generation was not impacted.” (more…)
