About electricity in Hawaii
Hawaii relies on oil to generate electricity more than any other state, which is the main reason its prices are the highest in the country. Each island runs its own separate grid, so power cannot be shared between islands or imported from the mainland.
- oil 75%
- solar 10%
- wind 6%
- geothermal 3%
- biomass 2%
- other 4%
The Hawaii Public Utilities Commission is the state agency that regulates electric utilities in Hawaii.
