In an effort to reduce its dependence on imported fossil fuels, the state of Hawai’i, in partnership with the U.S. Department of Energy (DOE), launched the Hawai’i Clean Energy Initiative (HCEI) in 2008. The goal of HCEI is to achieve 70% clean energy by 2030 through renewable energy and energy efficiency.
Highlighted Energy Efficiency Projects
To meet the HCEI’sclean energy goal, 30% of Hawai’i’s electricity demand must be reduced through energy efficiency measures. Energy efficiency projects and accomplishments are highlighted below.
EV Ready Program
DOE’s State Energy Program provided $4.5 million in funding for Hawai’i’s Transportation Energy Diversification Electric Vehicle (EV) Ready Program to help implement EVs and related infrastructure, reduce the overall number of vehicle miles traveled, and expand the use of renewable fuels in the transportation sector.
Along with the EV Ready Program, the University of Hawai’i Maui College, in partnership with the Hawai’i State Energy Office, the Honolulu Clean Cities Coalition, and the University of California San Diego, received nearly $300,000 in funding from DOE to develop a comprehensive plan that addresses the deployment of EVs and charging infrastructure through renewable energy grid system analysis and EV charging permitting processes.
By 2012, Hawai’i exceeded the national average for charging ports with nearly 290, and also boasted 1,136 EVs on the road. Additionally, local residents who own an EV reap the benefits of using high-occupancy vehicle lanes, free parking at state-owned locations, and significant cost savings.
Hawai’i is also focusing on implementing renewable energy and energy efficiency in residential areas. Built in 2011, Oahu’s Kaupuni Village is the first net-zero energy affordable housing community in the state, achieving the U.S. Green Building Council’s Leadership in Energy and Environmental Design ® Platinum designation.
Led by Hawai’ian Home Lands Trust and its partners, with technical assistance from DOE and the National Renewable Energy Laboratory, each of the 19 single-family homes in Kaupuni Village uses 40% less energy than a standard-built baseline home. Energy efficiency and renewable energy features include ENERGY STAR® appliances, high-efficiency lighting and daylighting, natural ventilation, high-efficiency air conditioners, water-wise landscaping using native species, solar water heating, and rooftop solar panels.
Other Energy Efficiency Accomplishments
Additional energy efficiency accomplishments achieved as part of HCEI include:
- Established a 30% state energy efficiency portfolio standard to achieve 4,300 gigawatt-hours by 2030
- Created and deployed a Public Benefits Fund to finance building retrofits with leading-edge energy efficiency technologies
- Deployed a state “Lead By Example” program to encourage government buildings, fleets, and personnel to become leaders in applying best practices in energy efficiency and conservation
- Adopted new, highly efficient building codes (IECC 2006 or higher) in all Hawai‘i counties
- Decoupled the utility revenue stream from kilowatt-hour sales revenues, removing the disincentive to promote and enhance energy efficiency
- Enacted legislation in 2013 allowing the State of Hawaii Department of Business, Economic Development, and Tourism to issue Green Infrastructure Bonds to secure low-cost financing for clean energy installations, including both renewable energy and energy efficiency measures.
Highlighted Electricity Generation Accomplishments
In addition to implementing energy efficiency to meet the 70% goal, 40% of Hawai‘i’s electricity must be generated by renewable resources, including solar, wind, geothermal, hydropower, and biofuels. Electricity generation accomplishments achieved as part of HCEI are highlighted below.
- Implemented four new wind projects: Kahuku (30 megawatts [MW]), Kaheawa II (21 MW), Auwahi (21 MW), Wailaloa (69 MW)
- Increased distributed solar from 12 MW in 2008 to 300 MW in 2013
- Established a state renewable portfolio standard of 40% by 2030
- Completed an energy agreement between the Hawaiian Electric Company and the state that includes energy commitments, measures to increase energy efficiency, and improvements to grid operation and infrastructure
- Led the nation in growth rate of distributed generation photovoltaic installation
- Met nighttime demand on the Big Island with 80% renewable energy from geothermal, biomass, and wind
- Created a Permitting Facilitator position in the State Energy Office to facilitate siting and permitting of renewable energy projects
- Completed the Hawai‘i Bioenergy Master Plan.
