Hawaii will shift its renewable portfolio standard to 100% by 2045, requiring all its electricity supply to come from sources like solar and wind, under a bill that passed the state legislature last week.
The measure caps an effort to transform the islands’ power grid from 90% reliance on fossil fuels to 100% clean energy.

In an email to Think Progress, State Senator Mike Gabbard called the 100% RPS “the biggest energy turnaround in the country,” noting that “we’ll now be the most populated set of islands in the world with an independent grid to establish a 100% renewable electricity goal.”
The bill will automatically become law this Friday unless Gov. David Ige vetoes it, Page writes. Hawaii’s previous RPS set a 40% renewable goal for 2030; the 100% target is the first for any U.S. state.
