Emerging Resources/New Applications Expand Reach of Geothermal Energy
• Small Heat and Power Systems – expand geothermal into distributed generation
• Co-production from oil/gas wells and geopressured resources –potential in many non-Western states, particularly the Gulf of Mexico.
• Enhanced Geothermal Systems/Deep Geothermal – potential nationwide and worldwide (witness recent Google announcement on finding 18,000 MW of geothermal in West Virginia!)
