Finance: Research Finds that Geothermal is Competitive With Other Renewables in Terms of Costs and Hazards

Renewable Energy in Hawaiʻi: A Comparative Analysis of Wind, Solar, and
Geothermal Energy Resources (HGGRC)

By Theodore Brennis, Hawaii Groundwater and Geothermal Resources Center

Project Methodology: Compare the land use, cost and hazards of three hypothetical renewable resources with similar power delivery capabilities using Puna Geothermal Venture (PGV) as the model for comparison.

Hawaii Public Radio interview with Theodore Brennis

Final Thoughts: 
  • Geothermal has the lowest land use of all non-nuclear, non-hydrocarbon renewable resources
  • Geothermal is competitive with other renewables in terms of costs and hazards
  • Geothermal provides clean, renewable baseload energy 
  • Geothermal potential through most of the state is unknown
  • Limited research efforts to determine geothermal potential because its not a priority 
  • Our lives are energy intensive… 
  • Not in my backyard…but in someone else’s?
