Geothermal energy in the United States Geothermal Data System (NGDS). Through the NGDS, many older paper archives and drill logs that are stored at state geological surveys are now being digitized and made available for free to the public. The underground hot water and steam used to generate geothermal power may contain chemicals that could pollute the air and water if released at the surface. Hydrogen sulfide, which is toxic in high concentrations, is sometimes found in geothermal systems. Newer methods of generating geothermal power separate the hot steam collected underground from the steam used to power turbines, and substantially reduce the risk of releasing air-polluting
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
