So if US switched entirely to wind turbines, what is the trade-off?
The solution to climate change is, at least conceptually, simple. Activities that add greenhouse gases to the atmosphere—chiefly the use of fossil fuels—need to be changed or eliminated. Of course, not every alternative to fossil fuels will be equally beneficial. Technologies have to be evaluated for costs and benefits. One thing we know about wind turbines, for example, is that they can alter local temperatures by increasing the mixing of air at and above the surface.
