Mid-ocean wind farms could power the entire world
According to a study from the Carnegie Institution for Science, big-scale offshore wind farms far out on the oceans could produce enough electricity to power the entire world thanks to stronger winds.
Researchers Anna Possner and Ken Caldeira from the Carnegie Institution explain in an article published in the Proceedings of the National Academy of Sciences that stronger winds (+ 70%) on the open ocean could produce up to five times more energy that those on land.
Therefore, building deep sea offshore wind farms could increase dramatically the amount of green power produced around the world.
Currently, not a single big scale wind farm has been installed in deep sea waters, but the study’s result indicate that this possibility is worth looking into it even if the power production could vary depending on the season.
“In winter, the North Atlantic wind farms could produce enough energy to power the entire civilization’s need”, explains the researchers, “on the other hand, in the summer this kind of wind farm could only produce enough energy to power Europe or the US”.
3 million square kilometres
The study bases its results on computer models that are compared to production results from big land wind farms from Kansas. The researchers foresee that to cover the current world’s needs an estimated 18 Terawatts would be required, a deep-sea wind farm that extends on 3 million square kilometres of ocean.
