Hawaii residents pay some of the highest utility bills in the country. Most of the state's electricity is produced from oil, which is not only one of the most expensive fuels used to generate electricity, it must also be shipped from the mainland, which increases the overall cost. And while solar power might seem like an obvious solution, the excess electricity generated by solar panels can overload circuits and burn up power lines. Hawaii has continued to work to improve energy costs, and according to Hawaii.gov, the state is striving for 100% renewable energy by 2045.
