Hawaiian Electric has said more than 70 percent of the rate it charges goes to pay for fuel-related costs directly or indirectly, and 70 percent of the state's electricity is generated by burning oil. The Hawaii Clean Energy Initiative, adopted by the state in 2008, set a goal that 40 percent of the state's electricity will be generated from renewable resources by 2030. At the end of 2013, 18 percent of the Hawaiian Electric's sales were made using renewable sources, surpassing the company's goal of 15 percent by 2015.
