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.
