- Children learning about geothermal energy will benefit from the Energy Information Administration’s EIA Energy Kids site, which hosts a straightforward article about the basics of geothermal energy, accompanied by useful illustrations, diagrams and photographs.
- Those interested in advanced information about the future of geothermal power in the U.S. should consult the analysis conducted by MIT in 2006. The report “evaluate[s] the technical and economic feasibility of EGS [Enhanced (or engineered) Geothermal Systems] becoming a major supplier of primary energy for U.S. base-load generation capacity by 2050.”
