Selective adaptation in technology. Or modernizing old methods.
In the first half of the last century wind generation of electricity could be found all over rural America. It was the only means to electrify many rural homes before the electric grid, that we take for granted, was constructed. The method was used out of necessity. It proved not to be cost effective once the grid was constructed.
Politicians and promoters have a way to make almost anything look good. Within twenty years these windmills will be replaced with a new technology that is better, cheaper, more efficient. At least that will be the story.
And life will go on.

Quaternary sea level changes and climate variations have played an important role in the evolution of landforms. Low sea levels can be equated to arid climates and high sea levels to humid climates. Low sea levels exposed large areas from which sand was blown from the west to the east, leading to dune building. High sea levels cut off the sand supply and allowed alluvial erosion and deposition from the mountains to dominate in the east.
