Geothermal resources in the US include dry steam, hot water, geopressurized water, hot dry rock, crustal gradients, and magma. The most recent US Geological Survey estimate shows that the energy content of magma located within 10 km of the surface is equivalent to 700 times the US energy consumption in 1974. Research is being conducted on the development of heat exchange systems for direct energy extraction from magma. Much of this research is under the auspices of USERDA. Sandia Laboratories is studying locations for magma experiments, methods of drilling, heat exchangers for magmatic environments, and heat transfer properties. Other applications of geothermal energy include domestic heating and electrical power generation from shallow and surficial steam and hot water sources. USERDA predictions and budgets for various energy sources are graphed. Renewable energy sources other than geothermal are reviewed. These include solar, wind, ocean thermal, and biomass.
