Geothermal Energy In The United States
Geothermal energy in the United States was first used for electric power production in 1960. The Geysers in Sonoma and Lake counties, California was developed into what is now the largest geothermal steam electrical plant in the world, at 1,517 megawatts. Other geothermal steam fields are known in the western United States and Alaska. Geothermally generated electric power can be dispatchable to follow the demands of changing loads. Environmental impact of this energy source includes hydrogen sulfide emissions, corrosive or saline chemicals discharged in waste water, possible seismic effects from water injection into rock formations, waste heat and noise. History Archaeological evidence documents that geothermal resources have been in use in the US for more than 10,000 years. Paleo-Indians first used geothermal hot springs for warmth, cleansing, and minerals. Pacific Gas and Electric opened the US' first commercial geothermal power plant at The Geysers in California in Septe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Enhanced Geothermal Systems
An enhanced geothermal system (EGS) generates geothermal electricity without natural convective hydrothermal resources. Traditionally, geothermal power systems operated only where naturally occurring heat, water, and rock permeability are sufficient to allow energy extraction. However, most geothermal energy within reach of conventional techniques is in dry and impermeable rock. EGS technologies expand the availability of geothermal resources through stimulation methods, such as 'hydraulic stimulation'. Overview In many rock formations natural cracks and pores do not allow water to flow at economic rates. Permeability can be enhanced by hydro-shearing, pumping high-pressure water down an injection well into naturally-fractured rock. The injection increases the fluid pressure in the rock, triggering shear events that expand pre-existing cracks and enhance the site's permeability. As long as the injection pressure is maintained, high permeability is not required, nor are hydraul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
USDOE
The United States Department of Energy (DOE) is an executive department of the U.S. federal government that oversees U.S. national energy policy and energy production, the research and development of nuclear power, the military's nuclear weapons program, nuclear reactor production for the United States Navy, energy-related research, and energy conservation. The DOE was created in 1977 in the aftermath of the 1973 oil crisis. It sponsors more physical science research than any other U.S. federal agency, the majority of which is conducted through its system of National Laboratories. The DOE also directs research in genomics, with the Human Genome Project originating from a DOE initiative. The department is headed by the secretary of energy, who reports directly to the president of the United States and is a member of the Cabinet. The current secretary of energy is Chris Wright, who has served in the position since February 2025. The department's headquarters are in southweste ...

American Recovery And Reinvestment Act Of 2009
The American Recovery and Reinvestment Act of 2009 (ARRA) (), nicknamed the Recovery Act, was a Stimulus (economics), stimulus package enacted by the 111th U.S. Congress and signed into law by President Barack Obama in February 2009. Developed in response to the Great Recession, the primary objective of this federal statute was to save existing jobs and create new ones as soon as possible. Other objectives were to provide temporary relief programs for those most affected by the recession and invest in infrastructure, education, health, and renewable energy. The approximate cost of the economic stimulus package was estimated to be $787 billion at the time of passage, later revised to $831 billion between 2009 and 2019. The ARRA's rationale was based on the Keynesian economic theory that, during recessions, the government should offset the decrease in private spending with an increase in public spending in order to save jobs and stop further economic deterioration. The politics a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Newberry Volcano
Newberry Volcano is a large, active, shield-shaped stratovolcano located about south of Bend, Oregon, United States, east of the major crest of the Cascade Range, within the Newberry National Volcanic Monument. Its highest point is Paulina Peak. Newberry is the largest volcano in the Cascade Volcanic Arc, with an area of when its lava flows are taken into account. From north to south, the volcano has a length of , with a width of and a total volume of approximately . It was named for the geologist and surgeon John Strong Newberry, who explored central Oregon for the Pacific Railroad Surveys in 1855. The volcano contains a large caldera, in diameter, known as the Newberry Caldera. Within the caldera are two lakes: Paulina Lake and East Lake. The volcano and its vicinity include many pyroclastic cones, lava flows and lava domes; Newberry has more than 400 vents, the most of any volcano in the contiguous United States. Glaciers may have once been present at the volcano, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geothermal Exploration
Geothermal exploration is the exploration of the subsurface in search of viable active geothermal regions with the goal of building a geothermal power plant, where hot fluids drive turbines to create electricity. Exploration methods include a broad range of disciplines including geology, geophysics, geochemistry and engineering. Geothermal regions with adequate heat flow to fuel power plants are found in rift zones, subduction zones and mantle plumes. Hotspot (geology), Hot spots are characterized by four geothermal elements. An active region will have: # Heat Source - Shallow magmatic body, decaying radioactive elements or ambient heat from high pressures # Reservoir - Collection of hot rocks from which heat can be drawn # Geothermal Fluid - Gas, vapor and water found within the reservoir # Recharge Area - Area surrounding the reservoir that rehydrates the geothermal system. Exploration involves not only identifying hot geothermal bodies, but also low-density, cost effective r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Energy Policy Act Of 2005
The Energy Policy Act of 2005 () is a federal law signed by President George W. Bush on August 8, 2005, at Sandia National Laboratories in Albuquerque, New Mexico. The act, described by proponents as an attempt to combat growing energy problems, changed US energy policy by providing Energy subsidies#Allocation of subsidies in the United States, tax incentives and loan guarantees for energy production of various types. The most consequential aspect of the law was to greatly increase ethanol production to be blended with gasoline. The law also repealed the Public Utility Holding Company Act of 1935, effective February 2006. Provisions General provisions * The Act increases the amount of biofuel (usually ethanol) that must be mixed with gasoline sold in the United States to by 2006, by 2009 and by 2012; two years later, the Energy Independence and Security Act of 2007 extended the target to by 2022. * Under an amendment in the American Recovery and Reinvestment Act of 2009, ...
