Wind power is growing faster than ever — almost half of the new sources of electricity added to the U.S. power grid last year were wind farms.

But is the sky the limit? Several scientists now say it's actually possible to have so many turbines that they start to lose power. They steal each other's wind.

In an op-ed in Foreign Policy, James Holmes argues if and when that icy expanse opens regularly to shipping, the Arctic will need policing like any other marine thoroughfare, and he nominates the United States Coast Guard.
