Hawaii could power itself off geothermal alone
It may not come as a surprise that a string of volcanic islands in the middle of the Pacific Ocean have some substantial geothermal energy resources. CleanTechnica notes a recent report from the Hawaii County Geothermal Working Group suggests the state could easily supply all of its energy needs with renewable electricity from geothermal power plants.
While most people are familiar with the ideas of wind and solar power systems, geothermal is generally in the spotlight less often. These power plants use heat from deep down in the earth to heat water into steam, which is then used to produce power.
Geothermal energy is plentiful particularly in geologically active areas, and islands like Hawaii certain fit that bill. The report suggests that the available geothermal resources could prove as much as seven times the state's current electricity needs in green energy.
Though the state only has one geothermal plant, the report found this plant helped lower electricity rates in the state, which pays more for power than anywhere in the country.
The U.S. Energy Information Administration reports that Hawaiian residents paid an average of 24.2 cents per kilowatt-hour in 2009.
