Heart of Hawaii: Oil Powers Oahu’s Sustainable Energy Program

By David Shormann -- June 10, 2020

… on Oahu, generating 1 MW of power using wind and solar requires 154 acres of land. That’s more than 800 times as much land as the Kahe petroleum-fired power plant requires to generate the same amount of power. Using wind/solar projects to produce the same amount of electricity Oahu utilities produced in January 2020 would require … almost one-third of Oahu … be covered with solar panels, wind turbines, and battery storage systems.

On Oahu’s west side, a Hawaiian green sea turtle snuggles up to a reef for an afternoon nap. But this is no ordinary reef. It’s the warm water outflow structure for Oahu’s biggest electric power producer, the Kahe Power Plant.

Built in the early 1960’s, the 651 megawatt (MW) workhorse often provides over 40% of Oahu’s power.…

Ocean Plastic Cleanup: Unintended Consequences (artificial habitat for mahi-mahi and more)

But as I started to pull the net in, I saw a huge mahi-mahi resting in its shade. Also known as dorado or dolphinfish, the mahi-mahi (spooked by my activity) disappeared in a flash.
