Hot dry rock geothermal energy Hot dry rock geothermal energy Hot dry rock (HDR) is an abundant source of geothermal energy available for use. A vast store of thermal energy is contained within hot - but essentially dry - impervious crystalline basement rocks found almost everywhere deep beneath the earth’s surface. A concept for the extraction of useful amounts of geothermal energy from HDR originated at the Los Alamos National Laboratory in 1970, and Laboratory researchers were awarded a U.S. patent covering it. Although often confused with the relatively limited hydrothermal resource already commercialized to a large extent, HDR geothermal energy is very different. Whereas
Energy in the United States biogenic municipal solid waste and other waste biomass. Using the data from the US DOE Energy Information Administration/Electric Power Annual 2015 files Data was obtained from the most recent DOE Energy Information Agency (EIA) full year files. The following table derived from data mined from Electric Power Annual . identifies those states which generate more electrical energy than they need to meet their consumption needs. They supply those that need additional energy. Each states total electric generation for 2016 is compared with the states consumption and its share of the system loses and the difference between the generated electric energy
