Energy Quote

The state's combination of abundant renewable resources, high fuel prices, limited geographic area, and recognized expertise in hydrogen technology R&D, makes it an ideal location to lead the state's transition to a renewable energy-to-hydrogen economy. By attracting considerable investments of capital and expertise to Hawaii, we will be investing wisely for our future needs.

Geothermal Power

A Brief Description:

Geothermal power is electricity generated by utilizing naturally occurring geological heat sources. It is a form of renewable energy.

Geothermal power is generally harnessed in one of three ways. Large scale electrical generation is possible in areas near geysers or hot springs by utilizing naturally occurring steam, superheated ground water or using geothermal heat to heat a heat-transfer fluid. Experiments are in progress to determine if a fourth method, deep wells into "hot dry rocks", can be economically used to heat water pumped down from the surface. A hot dry rock project in the United Kingdom was abandoned after it was pronounced economically unviable in 1989. HDR programs are currently being developed in Australia, France, Switzerland and Germany. Magma (molten rock) resources offer extremely high-temperature geothermal opportunities, but existing technology does not allow recovery of heat from these resources.
