Geothermal Energy In The United States
Geothermal energy was first used for electric power production in the United States in 1960. The Geysers in Sonoma and Lake counties, California was developed into the largest geothermal steam electrical plant in the world, at 1,517 megawatts. Other geothermal steam fields operate in the western US and Alaska. Geothermal power can be dispatchable to follow the demands of changing loads. Its environmental impact includes hydrogen sulfide emissions, corrosive or saline chemicals discharged in waste water, possible seismic effects from 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 September 1960, initially producing eleven megawatts of net power. The ...

Oregon
Oregon () is a U.S. state, state in the Pacific Northwest region of the Western United States. The Columbia River delineates much of Oregon's northern boundary with Washington (state), Washington, while the Snake River delineates much of its eastern boundary with Idaho. The 42nd parallel north, 42° north parallel delineates the southern boundary with California and Nevada. Oregon has been home to many Indigenous peoples of the Americas, indigenous nations for thousands of years. The first European traders, explorers, and settlers began exploring what is now Oregon's Pacific coast in the early-mid 16th century. As early as 1564, the Spanish expeditions to the Pacific Northwest, Spanish began sending vessels northeast from the Philippines, riding the Kuroshio Current in a sweeping circular route across the northern part of the Pacific. In 1592, Juan de Fuca undertook detailed mapping and studies of ocean currents in the Pacific Northwest, including the Oregon coast as well as ...

Enhanced Geothermal Systems
An enhanced geothermal system (EGS) generates geothermal electricity without the need for natural convective hydrothermal resources. Until recently, geothermal power systems have exploited only resources where naturally occurring heat, water, and rock permeability are sufficient to allow energy extraction. However, by far the most geothermal energy within reach of conventional techniques is in dry and impermeable rock. EGS technologies enhance and/or create geothermal resources in this hot dry rock (HDR) through a variety of stimulation methods, including 'hydraulic stimulation'. Overview When natural cracks and pores do not allow economic flow rates, the permeability can be enhanced by pumping high-pressure cold water down an injection well into the rock. The injection increases the fluid pressure in the naturally fractured rock, triggering shear events that enhance the system's permeability. As long as the injection pressure is maintained, a high matrix permeability is not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

American Recovery And Reinvestment Act Of 2009
The American Recovery and Reinvestment Act of 2009 (ARRA) (), nicknamed the Recovery Act, was a 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 around the stimulus w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vancouver Sun
The ''Vancouver Sun'', also known as the ''Sun'', is a daily broadsheet newspaper based in Vancouver, British Columbia, Canada. The newspaper is currently published by the Pacific Newspaper Group, a division of Postmedia Network. Published six days a week from Monday to Saturday, the ''Sun'' is the largest newspaper in western Canada by circulation. The newspaper was first published on 12 February 1912. The newspaper expanded in the early 20th century by acquiring other papers, such as the ''Daily News-Advertiser'' and ''The Evening World''. In 1963, the Cromie family sold the majority of its holdings in the ''Sun'' to FP Publications, who later sold the newspaper to Southam Inc. in 1980.

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. 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 regions to drill a ... [...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, ...

Salton Sea
The Salton Sea is a shallow, landlocked, highly saline body of water in Riverside and Imperial counties at the southern end of the U.S. state of California. It lies on the San Andreas Fault within the Salton Trough that stretches to the Gulf of California in Mexico. Over millions of years, the Colorado River has flowed into the Imperial Valley and deposited alluvium (soil), creating fertile farmland, building up the terrain, and constantly moving its main course and river delta. For thousands of years, the river has alternately flowed into the valley, or diverted around it, creating either a saline lake called Lake Cahuilla, or a dry desert basin, respectively. When the Colorado River flows into the valley, the lake level depends on river flows and the balance between inflow and evaporative loss. When the river diverts around the valley, the lake dries completely, as it did around 1580. Hundreds of archaeological sites have been found in this region, indicating possibly long-ter ...
