Hawaii was the first state to set a deadline for generating 100% of its electricity from renewable sources, which is required to be achieved by 2045.

Hawaii’s mild climate contributed to the state being among the five states with the lowest total energy use and per capita energy consumption. 

In 2018, solar power provided more than half of Hawaii's total renewable generation, primarily because of the growth of small-scale, customer-sited solar photovoltaic generation, which has almost doubled since 2014. 

The amount of Hawaii's total coal-fired generation in 2018 was the lowest since 1992, and coal-fueled 13% of the state’s electricity generation. 

Hawaii's dependence on imported petroleum, much of which is used for electricity generation, contributes to Hawaii having the highest average retail electricity price for all sectors of any state.
