NASA satellites show offshore wind potential
The wind blows strong and steady out at sea. NASA releases maps to measure where wind energy on the the oceans is best for setting up turbines.
NASA's Jet Propulsion Laboratory released images on Wednesday depicting offshore wind energy potential around the world.
Gathered from almost 10 years of satellite data, the wind maps can be used by offshore wind energy developers to measure which sites have the best resource.
The best sites, depicted in red, have a steady and high wind speed for most of the year. Offshore wind turbines have the advantage of not having wind blocked by buildings or land formations.
Wind energy could supply 10 percent to 15 percent of the world's electricity needs, said Paul Dimotakis, chief technologist at NASA's Jet Propulsion Laboratory.
Dimotakis said offshore wind turbines could produce electricity cheaper than solar energy could.
There are no offshore wind farms in the United States, but many expect that it's a matter of time before one will be built. New types ofso that they can be anchored farther offshore.
The, though highly criticized, is moving forward in its approval process. And a project led by Bluewater Wind off the coast of Delaware was recently approved by the state legislature.
Earlier this week, oil prospector, which set the goal of getting 20 percent of U.S. electricity in 10 years from land-based wind turbines in the
