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
Notes from Underground after because of such an indulgence in society. The shame displayed here is what separates him from rational egoists and utopian dreamers, but the desire that he sometimes feels to buy into such ideals leaves him on the fringe of society or what can be understood as what drove him underground.
