Jeffrey Mikulina, a longtime environmental activist in Hawaii, jokes that his home state, which is almost completely dependent on imported oil, is one supertanker away from being Amish. It also is one superheated ocean away from being underwater.

There, in a nutshell, is the motivation behind a new campaign to wean Hawaii from fossil fuels in 10 years. The project is Hawaii’s own moon mission, led by the Blue Planet Foundation and not by the state’s political establishment, which tends to prefer the slow and tortured way to change (a long battle over a new commuter rail system was bogged down by a ferocious debate over whether it should have steel or rubber wheels).

Blue Planet, a private foundation, is the creation of Henk Rogers, a software entrepreneur who made a fortune in Tetris. Reassessing his life after a heart attack two years ago, he decided to pursue a goal that for decades has been as elusive as it is drop-dead obvious.

Hawaii is as energy-hungry as any state, but it has no oil, natural gas, hydroelectric dams or nuclear plants. It needs imported crude to keep the lights on, but it also has an abundance of clean-energy sources: sunshine, wind, powerful tides and waves and cold ocean depths.
