Hawaii State Energy Office (HSEO) Energy Efficiency Revolving Loan Fund is sponsored by HSEO. Offers low-interest loans for energy efficiency projects in Hawaii.

Homepage - Hawai‘i State Energy Office The State of Hawai‘i has a bold energy agenda — to achieve 100 percent clean energy by the year 2045. Along with reducing our islands’ dependency on fossil fuels and increasing efficiency measures, the energy plan also contributes to the state’s economic growth.

Because Hawai‘i is committed to repowering the clean energy economy, we have embraced bold solutions that will help develop a competitive market for utility-scale and distributed energy resources, making Hawai‘i a leader in the clean energy transition. In the aftermath of the deadly Lahaina wildfires of 2023, the Hawaiʻi State Energy Office (HSEO) was tasked by Governor Josh Green, M. D.

to develop a new energy strategy to reduce energy costs and carbon emissions in the electricity sector, and achieve three key objectives: Evaluate options to replace residual fuel oil for power generation. Create opportunities for capital investment in grid infrastructure and power generation to ensure and enhance energy system reliability and resilience. Accelerate Hawai‘i’s energy transition to renewable and carbon-free energy.

Life on the Hawaiian archipelago has been shaped by elemental energy sources — wind, water, earth, sun, moon, and sky. The Hawaiian creation story told through the Kumulipo tells of the interconnected relationship between humankind and nature. An ancestral link to nature’s life-giving and life-sustaining energy is a core feature of the Hawaiian cultural value system.

We often see it expressed through mālama ‘āina: the care and stewardship of the environment and natural resources. Energy is a shared natural resource that connects us to the past and provides our foundation for the future.

HSEO fulfills its mission to residents through strategy and thought leadership; program design and implementation; analysis, reporting, and data collection and sharing; regulatory support; and education, outreach, and community/public engagement. The goal of the Hawai‘i Clean Energy Initiative is to achieve 100 percent clean energy by 2045.

Through collaboration between thought leaders and committed groups and individuals, HCEI builds upon the dynamic, ongoing work of public and private organizations at the national, state, and county level Hawai’i Clean Energy Initiative The Hawaiʻi State Energy Office promotes energy efficiency, renewable energy, and clean transportation to help achieve a resilient clean energy economy.

HSEO’s primary roles and activities are set forth in Sections 196-71 and 196-72, Hawaiʻi Revised Statutes. Hawai‘i’s Energy Landscape Hawai‘i’s embrace of clean energy is rooted in a commitment to ending its dependence on fossil fuels.

In this section, you can learn about the energy sources utilized in Hawai‘i, the differences between renewable and non-renewable sources, and the multitude of energy projects currently ongoing in our state.

Explore the Current Landscape Hawai’i Statewide Energy Flowchart AES Hawaiʻi’s 60 MW Kūihelani Solar Plus Storage is the largest solar power facility in the state, generating enough electricity for 27,000 homes, with a 240 MWh battery energy storage system. Current and open Requests for Interest (RFI) and Requests for Proposal (RFP) issued by HSEO are linked here and on the Hawaii Awards and Notices Data System (HANDS).

Hawaii Awards & Notices Data System Alternative fuels, repowering, and energy transition study Governor Josh Green, M. D.

, tasked HSEO with developing a new energy strategy to reduce energy costs, increase generation reliability and resilience, and achieve carbon emission reductions in the electricity sector, post-Maui wildfires, while achieving two key objectives: Accelerate Hawaiʻi’s energy transition to renewable and carbon-free energy.

Evaluate options to replace residual fuel oil for power generation and to ensure and enhance energy system reliability and resilience. The Alternative Fuel, Repowering, and Energy Transition Study builds on more than ten years of related studies.

It is one part of a broader effort to develop an energy transition strategy to support national security, safeguard energy infrastructure, increase energy affordability, and accelerate renewable energy adoption.

Alternative Fuels, Repowering, and Energy Transition Study Alternative Fuels, Repowering, and Energy Transition – Final Report and Documents Informational Briefing to the House Committee on Energy & Environmental Protection Act 238, Session Laws of Hawai’i 2022, tasks the Hawai‘i State Energy Office to “analyze pathways and develop recommendations for achieving the State’s economy-wide decarbonization goals.

” Additionally, the study evaluates emission reduction pathways from all emitting sectors economy-wide. Pursuant to Hawai’i Revised Statutes §225P-5, Hawai’i has a target “to sequester more atmospheric carbon and greenhouse gases than emitted within the State as quickly as practicable, but no later than 2045”, effectively establishing a net-negative emissions target.

Find reports, studies, research papers, resource assessments, and more.

Solar Water Heater Mandate An online application was developed to help expedite the submittal of a request for variance (exemption) from Hawai‘i Revised Statutes §196-6. 5, which mandates that, effective January 1, 2010, all new single-family dwellings (which includes Accessory Dwelling Units and similar single-family dwellings) built in the State of Hawai‘i have a solar water heater.

The Hawaiʻi Fuel Imports Dashboard is an interactive data visualization illustrating from where Hawaiʻi imports the various fuels consumed across the islands. Using fuel shipment data the dashboard identifies the broad array of fuels that are imported into and consumed in Hawaiʻi. The islands of Hawai‘i have abundant natural resources such as wind, solar, geothermal, bioenergy, and hydropower.

These precious resources could potentially meet a substantial portion of Hawai‘i’s energy needs. Use this interactive directory to find and learn about renewable energy projects in Hawai‘i. he Hawaiʻi Statewide Energy Flowchart is an interactive data visualization that illustrates the flow of energy throughout the statewide economy.
