Electricity: Renewable/Efficiency

By 2030, increase renewable energy in the electricity sector to 40% of total annual output.

Hawai‘i is determined to achieve its goal of 40 percent renewable energy in the electricity sector and a reduction of electricity consumption by 4,300 gigawatt-hours by 2030 as a mid-term goal on the way to 100 percent renewable energy generation by 2045. Currently, only renewable energy for electricity is being tracked for this goal until Hawai‘i Energy Efficiency Portfolio Standards are released in 2019. Pursuing energy independence and transitioning off fossil fuels achieves a dual purpose: stimulating smart growth that benefits future generations in Hawaii and delivering cost-effective energy that is environmentally friendly.

Hawai‘i Renewable Portfolio Standards (RPS) by Utility/County

Figure 1: The above chart shows the percentage of energy sales from renewables in each county and for the state as a whole. While each island has its own characteristics and mix of renewables, note that in 2017 the state reached 27.7% of total energy sales from renewables, which is on track to meet the 2030 goal.

The Renewable EnerGIS tool developed by the Hawaiʻi State Energy Office supports the siting of renewable energy projects by providing information on specific Hawaii parcels to help inform the site assessment process, including renewable energy resource indicators, climate, topography, zoning, and other relevant site characteristics. This tool also empowers users to query sites in Hawaiʻi with certain attributes that may or may not be desired for development such as island, acreage, solar radiation, land use district, soil type(s), potential warm groundwater, and/or the presence of critical habitat(s), special management area(s), and reserve(s). Renewable EnerGIS benefits a broad audience by providing information that can be used by landowners, developers, communities, individuals, regulatory entities, policy makers, non-government organizations, and other stakeholders.

Figure 5: The graph on the left represents the energy efficiency potential in Hawaiʻi. The dashed black line indicates the current trajectory of Hawaiʻi's electric energy spending; however, the blue dashed line indicates the Energy Efficiency Portfolio Standard (EEPS) goal, aiming for 30% reduction of electrical energy by 2030. Lastly, the purple dashed line indicates Hawaiʻi's Clean Energy Initiative (HCEI) target of 70% reduced electrical energy.
