Climate change
Since the beginning of the industrial age in the 1800s, the addition of more carbon dioxide (CO₂) and other gases (e.g., methane [CH₄] and nitrous oxide [N₂O or NOx]) to the atmosphere than can be naturally absorbed (e.g., by plants and bodies of water) is widely thought to have caused an unnatural warming of the planet.
Consequently there is a push to reduce CO₂ and other emissions to slow, if not reverse, that warming. That push is used to promote the large-scale development of wind energy and to overcome objections of cost and adverse environmental effects, as well as to avoid questions of actual benefit.[1]
But any controversies over the science or politics of anthropogenic climate change are irrelevant to the arguments for wind energy. If there is a need to reduce CO₂ and other emissions, then wind energy has proved to be ineffective.[1][2] With that acknowledgement, the costs and adverse impacts of wind energy far outweigh any other benefits that might be claimed and that remain minuscule.
