Energy Efficiency and Least-Cost Planning: The Best Way to Save Money and Reduce Energy Use in Hawaii

Abstract

If the 500 MW geothermal project on the Big Island of Hawaii is developed as planned, the Wao Kele O Puna rain forest will be severely damaged or destroyed. If this happens the State will lose one of its most precious resources. It would be tragic for this to happen, since on a least-cost basis, the geothermal project does not make economic sense. Improving energy efficiency in the commercial and residential sectors of Hawaii can save about 500 MW of power at a cost of $700 million.
