A deep-sea wind farm would have to operate in remote and harsh conditions where waves frequently exceed three metres, according to the researchers.
The two authors of the study Anna Possnera and Ken Caldeira, from the Carnegie Institution for Science in Stanford, California, said that the new research is a kind of green light for the wind energy industry from a geophysical point of view. Land-based turbines themselves slow the air reducing the amount of energy subsequent rows of turbines can generate.
Scientists have been wondering just how much power a wind turbine located far offshore could actually produce.
The study found that such a huge wind farm could capitalize on low-pressure systems throughout the winter which more efficiently combine the upper atmospheric winds with the surface level winds, producing greater yields in wind farm power generation potential. Several past studies indicate that the rate of electricity generation for large wind farms on land may be limited to approximately 1.5 watts per square meter. "Will sticking giant wind farms out there just slow down the winds so much that it is no better than over land?"
Wind farms in the open ocean can generate far more renewable energy than those on land, possibly enough to power the whole world, said a USA study on Monday, 9 October.

AAA: "Infotainment" systems distracting drivers
Carmakers are cramming more and more technology into our cars-including the ones we still have to drive. Previous AAA research indicates one in three USA adults use infotainment systems while driving .
The team used computer models to compare the output of existing land-based wind farms in Kansas to huge, theoretical facilities out in the open ocean. In doing so, they established that the speed of the wind over the open ocean is some 70 percent higher than that on land.
As a result, more energy is drawn from the atmosphere than over land, which helps to combat the problem of turbine drag.
Till date, the wind energy is obtained through wind turbines which convert the kinetic energy of the wind into mechanical power, and then the generator converts this mechanical power to electrical.
"There is something special about some ocean environments and there are places like the North Atlantic where the Gulf Stream and all of its heat is pouring into the atmosphere", said Caldeira.
"We found that giant ocean-based wind farms are able to tap into the energy of the winds throughout much of the atmosphere, whereas wind farms onshore remain constrained by the near-surface wind resources", says Anna Possner, co-author of the study. "The advent of this innovative technology will allow us to harness powerful wind speeds at much greater depths".
