In 1918, President Woodrow Wilson designated 322 acres (130 ha; 1.30 km²) of land on Mokapu Peninsula for the military. The Kuwaahoe Military Reservation, became known later, in 1942 as Fort Hase. In 1941, Army artillery units moved into the area.

Since 2004, MCBH has partnered with Ocean Power Technologies to test the generation of electric power from ocean waves using a "PowerBuoy" wave energy converter, one of the first wave power projects in the U.S.^[11]

The Azura wave power device is currently being tested in a 30-meter site at the base.^[12]

Marine Corps Base Hawaii, under commanding officer Col. Robert Rice, installed solar water heaters on all base housing units, and on 8 December 2010, was scheduled to debut a "Net Zero" sustainable energy home, which uses solar power. The base fleet of government vehicles is also being changed over to hybrid and electric vehicles and most other "FlexFuel" vehicles now operate on E85 ethanol-based fuel. MCB Hawaii installed the first E85 pump in the state of Hawaii in November 2010, the first U.S. military installation in the world to do so.^{[This paragraph needs citation(s)]}
