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.
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. With that acknowledgement, the costs and adverse impacts of wind energy far outweigh any other benefits that might be claimed and that remain minuscule.
