Unfortunate Fact
Wind could power the entire world
Wind could power the entire world
Wind power may be the key to a clean energy revolution: a new study in the Proceedings of the National Academy of Science finds that wind power could provide for the entire world’s current and future energy needs.
To estimate the earth’s capacity for wind power, the researchers first sectioned the globe into areas of approximately 3,300 square kilometers (1,274 square miles) and surveyed local wind speeds every six hours. They imagined 2.5 megawatt turbines crisscrossing the terrestrial globe, excluding “areas classified as forested, areas occupied by permanent snow or ice, areas covered by water, and areas identified as either developed or urban,” according to the paper. They also included the possibility of 3.6 megawatt offshore wind turbines, but restricted them to 50 nautical miles off the coast and to oceans depths less than 200 meters.

Using this criteria the researchers found that wind energy could not only supply all of the world’s energy requirements, but it could provide over forty times the world’s current electrical consumption and over five times the global use of total energy needs.
Turning to the world’s two largest carbon emitters, China and the United States, the researchers found that wind power has the potential to easily supply both nations.
“Large-scale development of wind power in China could allow for close to an 18-fold increase in electricity supply relative to consumption reported for 2005,” the researchers write. “The bulk of this wind power, 89%, could be derived from onshore installations. The potential for wind power in the U.S. is even greater, 23 times larger than current electricity consumption, the bulk of which, 84%, could be supplied onshore.”
Expanding their view to the top ten carbon emitters, the researchers found that Russia, Canada, and the United States (in this order) had the greatest capacity for wind power. However, they note that much of the area available for wind power in Russia and Canada is far from any cities, making their construction costly. In addition, the authors note that the public may oppose wind turbines in particular areas, especially remote, ecologically sensitive regions. Still, they conclude that “despite these limitations, it is clear that wind power could make a significant contribution to the demand for electricity” in most high carbon emitting countries.

This is a great article. I knew there was some huge potential for wind
power (and solar too), but did not realize it was to this extent.
