Hawaii's electrical energy mix is approximately 12% from all renewable sources. 70% of electrical generation is from petroleum (mostly Bio-Diesell) with the remainder from a single coal plant. Roughly half of that renewable energy supply is sourced from biomass and geothermal, which are both highly available and predictable. Solar provides roughly 8% of Hawaii's renewable energy or less than 1% of its total electrical energy supply. Wind energy provides roughly 30% of the renewable supply or 4% of the total. Based on these numbers, solar production is far from saturated.
