KANEOHE BAY, Hawaii (AP) — The ocean's vast, endless movement packs the power to meet a quarter of America's energy needs.
Nevertheless, wave energy technology lags well behind wind and solar power, with technical hurdles still to be overcome.
To help accomplish that, the Navy is testing wave energy devices in the turquoise waters off Hawaii.
The project consists of two buoys that generate electricity from the up-and-down and side-to-side movement of the ocean.
Some of the modest amount of current generated is being fed into Oahu's power grid. Experts say it is the first wave-produced electricity to go online in the U.S.

The cables in the middle move up and down with the waves, turning the wheels of generators in the donut-shaped Lifesaver device, which is deployed at the Navy's Wave Energy Test Site at the Marine Corps base at Kaneohe Bay on Oahu in Hawaii. By some estimates, the ocean's endless motion packs enough power to meet a quarter of America's energy needs and dramatically reduce the nation's reliance on oil, gas and coal.
