Marine Corps Base Hawaii, under commanding officer Col. Robert Rice, has stopped using plastic shopping bags aboard the installation, installed solar water heaters on all base housing units, and on December 8, 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.
