Renewable Resources Potential e Hawaii's indigenous, renewable natural resources have the potential to make the State energy self- sufficient Hawaii's geological age and volcanic activity make geothermal resource a high potential option e Geothermal energy offers relatively non-polluting, reliable, base load power at competitive cost
Supply and Demand Preliminary estimates of potential geothermal resources in the Puna region are on the order of 500 e megawatts for 100 years Hawaii Electric Light Company (Big Island) demand projections call o for additional load capacity by early 1990's Biomass (bagasse) incineration from the sugar mills now provides o roughly 40 percent of the island's electrical energy e Hawaiian Electric Company (Oahu) demand projections call for o additional load capacity and equipment retirement by early to mid 1990's. Geothermal power transmission via an undersea cable system could supply half of HECO's requirements
Scientific Observation Hole Program Regional assessment of geothermal resource in Kilauea middle and e lower East Rift Zone (Hawaii) and Haleakala Southwest Rift Zone Non-production coreholes for scientific evaluation, observation, and monitoring Information to be gained for SOHs: o subsurface geological conditions o groundwater level, composition, and quality o subsurface temperature and pressure e o drilling conditions o assessment of possible mineral & geothermal resources o eruptive history of the island to the depth drilled
