What is geothermal’s long-term outlook in Hawaii?
Geothermal is one of Hawaii’s strongest energy building blocks. Unlike solar and wind power, it is what’s called a “firm” resource—always there. Years of development, state-of-the-art equipment, and attention to community concerns have made PGV a model facility. Geothermal energy is “clean,” it requires a relatively small area of land, and the cost per kWh is competitive—currently in the same range as oil. The cost of geothermal will remain stable, even if the cost of oil fluctuates. True, it is found only on the Big Island. Geothermal could fulfill all of the energy needs of Hawaii County, though it is doubtful that regulators would put all their energy eggs in one basket. Beyond that, geothermal could be used to power plants that produce biofuels. And it could be sent to the Natural Energy Lab for experimentation in the production of hydrogen fuel cells—one of the newest technologies in the energy field.
Expanding opportunities for direct use would help many small businesses on the Island by reducing the high cost of conventional power.
