A mixture of provide chain points, delayed permits and different bureaucratic hurdles have slowed the progress of renewable vitality tasks that might change coal vitality in Oahu. A variety of these might come on-line as early as the primary half of 2023, officers say. Within the meantime, vitality suppliers will lean extra closely on oil.
Whereas there shall be destructive short-term penalties, closing the coal plant strikes the state towards vitality resiliency and independence in the long run, supporters of the choice say.
“Coal and oil are assets that we don’t and won’t ever produce a variety of domestically,” mentioned State Consultant Nicole E. Lowen, a Democrat who’s the chairwoman of the Committee on Power and Surroundings. “That leaves us on the mercy of worldwide markets which can be past our management.”
