KANEOHE BAY, Hawaii — In the waters off the coast of Hawaii, a tall buoy bobs and sways in the water, using the rise and fall of the waves to generate electricity.
The current travels through an undersea cable for a mile to a military base, where it is fed into Oahu’s power grid — the first wave-produced electricity to go online in the U.S.
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. But wave energy technology lags well behind wind and solar power, with important technical hurdles still to be overcome.
To that end, the Navy has established a test site in Hawaii, with hopes the technology can someday be used to produce clean, renewable power for offshore fueling stations for the fleet and provide electricity to coastal communities in fuel-starved places around the world.
“More power from more places translates to a more agile, more flexible, more capable force,” Joseph Bryan, deputy assistant secretary of the Navy, said during an event at the site. “So we’re always looking for new ways to power the mission.”
Hawaii would seem a natural site for such technology. As any surfer can tell you, it is blessed with powerful waves. The island state also has the highest electricity costs in the nation — largely because of its heavy reliance on oil delivered by sea — and has a legislative mandate to get 100 percent of its energy from renewables by 2045.
