Where is geothermal energy used in Hawaii?
Geothermal energy is produced only on the Big Island for use on the Big Island. In the 1980s the state investigated the technical and economic feasibility of installing a 500-megawatt geothermal inter-island submarine cable in the formidable Alenuihaha Channel, known for its difficult weather. The rationale was that the energy source was on the Big Island but the population center was on Oahu. The project proved to be technically feasible, but too costly without considerable government subsidies.
