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]
