Demand Shifting in Hawaiʻi: The Other Half of the Energy Transition

The series examining Oʻahu’s energy transition has followed a consistent structure. It began by defining the island’s fully electrified energy system and stripping away energy uses that do not serve the civilian economy. Aviation fuel for flights leaving Hawaiʻi, maritime bunkering for ships crossing the Pacific, and military energy consumption … [continued]

Biomethane for Oʻahu: A Small Reserve With a Big Reliability Role

The starting point for evaluating biomethane in Hawaiʻi is the fully electrified Oʻahu energy system that emerged from the earlier Sankey analysis. That work removed overseas aviation fuel, long-distance maritime bunkering, and military energy use from the island energy balance. It also electrified transportation, buildings, and industry while replacing combustion … [continued]

District Cooling From the Pacific: A Targeted Efficiency for Oʻahu

The starting point for evaluating seawater air conditioning on Oʻahu is the fully electrified energy system for the island that has been developed through the earlier Sankey analysis. In that framework the island’s civilian energy system excludes overseas aviation fuel, maritime bunkering for ships crossing the Pacific, and military energy … [continued]

Wind on Oʻahu: A Modest but Valuable Complement to Solar

Any serious discussion of renewable energy on Oʻahu should begin with a clear understanding of how much electricity the island actually needs once fossil fuel end uses are electrified. Earlier analysis constructed a fully electrified civilian energy Sankey for Oʻahu that removed overseas aviation fuel, international maritime bunkering, and military … [continued]

Parking Lots, Rooftops, & Farms: Mapping Oʻahu’s Solar Potential

Any discussion of solar power on Oʻahu has to begin with the amount of electricity the island actually needs in a fully electrified system. Earlier analysis stripped out aviation fuel for overseas flights, fuel bunkered for ships leaving the islands, and military fuel use. It also electrified transportation, buildings, and … [continued]

Oʻahu’s Real Energy System: Stripping Away Aviation, Shipping, & Military Demand

Energy discussions about Hawaiʻi often begin with the largest numbers on the chart. Aviation fuel, maritime bunkering, and military logistics dominate many of the data tables that describe the state’s energy system. When those numbers are placed on a single chart, the scale of the challenge appears enormous and the … [continued]

Perspective Pivot: Mapping a Landscape of Voices in Oahu Changes Energy Planning

At the National Renewable Energy Laboratory (NREL), researchers often serve as guides who help communities navigate the world of renewable energy solutions. But in community-based technical assistance projects, the guiding role goes both ways: Researchers need local perspectives to fill contextual knowledge gaps and create more meaningful energy solutions. “Energy … [continued]
