Energy in South Australia and trap in the deeper heat. Due to the low permeability of granite, the hot rocks must undergo hydraulic fracturing and be stimulated to allow a flow of water through the system to produce energy. This heat is slowly conducted to shallower rocks near the surface. Petratherm propose developing the geothermal energy in the more permeable sedimentary rocks that overlay the hot granite, a process called Heat Exchange Within Insulator (HEWI). While somewhat cooler, in many cases they do not require hydraulic fracturing. It is estimated that one percent of geothermal energy shallower than five kilometres below the earth's surface
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
