The facts don’t support these assertions. The higher oil consumption is temporary until delayed utility scale solar and geothermal projects come online [1] (supply chain issues). A recent battery project with Tesla Megapacks [2] replaced AES’ coal plant for grid services.
The price of oil pushes renewables adoption velocity in this situation, as clean energy options are cheaper than burning oil for electricity. Before this closure, Oahu had roughly equal coal vs solar generation capacity (~200MW). It’s obviously cheaper to replace that coal generation with batteries that can charge from renewables.

Because oil is incredibly volatile. And we have to pay for it in a way that you don’t have to with solar battery.”

> Sandra Larsen, market business leader for AES in Hawaii, said the company supports the shuttering of its coal power plant and is now working on six renewable energy projects across the state’s four island counties. One of its projects, Kuihelani, is expected to generate power for about 27,000 homes on Maui.
