The basic physics of wind energy

In accordance with the 2nd law of thermodynamics, energy must flow from a concentrated form to a more diffuse form in order to do work.

Wind (and solar) is already diffuse, so it must first be concentrated (requiring a very large collection area, i.e., adverse impacts) to be useful, and second, because it is also intermittent and variable, be stored so it can be called upon as needed.

Both of these are substantial barriers to — and the basis of arguments against — practical large-scale use of wind (and solar) to provide electrical energy.
