It only makes sense that sunny and breezy Hawaii has become the first state in the U.S. to mandate a move to 100% renewable energy. In a 74-2 vote by the Hawaiian legislature, lawmakers have passed a bill that requires the state to be 100% dependent on renewable energy by the year 2045. The bill reads, in part, “The purpose of this Act is to update and extend Hawaii’s clean energy initiative and renewable portfolio standards to ensure maximum long-term benefit to Hawaii’s economy by setting a goal of one hundred per cent renewable by 2045.” This could be in the form of solar, wind, hydro, or geothermal power.

There are some roadblocks, reports ExtremeTech's Jimmy Rose:

Eliminating all carbon-based sources of electricity by 2045 could prove quite a challenge, as currently, 80% of Hawaii’s electricity is generated by oil. The state has the most expensive electricity rates in the country, thanks to having to import large quantities of oil to the islands. Reportedly, Hawaii pays 175% above the national average for their oil. The new law calls for 40% state dependence on renewable energy by 2030, and 70% by 2040.
