    Extractions: Geothermal Energy Nevada Geothermal Power Inc. (NGP:TSX ) is an alternative energy company focused on the development of large geothermal power projects in Western U.S.A. The company recently received funding from the US Department of Energy to further develop the strategic Blue Mountain geothermal project in Nevada. Blue Mountain has the potential to generate 100MW of energy to help meet the ever-growing demand for power in California and the Pacific Northwest. Because geothermal energy is a rapidly growing, clean alternative to coal, oil and gas-fired power plants, Nevada Geothermal represents an attractive investment opportunity in the energy sector. The Blue Mountain geothermal power project of Nevada Geothermal has many similarities to the Geysers field of Calpine Energy Geothermal energy (literally heat from the earth) has become the "green" energy alternative of choice because it is natural, clean, renewable, reliable, efficient and inexpensive to operate. The western U.S.A. has a generous endowment of geothermal potential. Nevada occupies the area of highest crustal heat flow in North America thanks to increased magmatic activity related to plate tectonics (see map below).

23. Alternative Energy Sources
    Some (alternative) energy sources are biomass, geothermal, hydroelectric, solar, wind power, fuel cells, ocean thermal energy conversion, tidal energy, and wave  
    http://www.pge.com/microsite/PGE_dgz/more/alternative.html
    
    Extractions: Alternative energy sources are resources that are constantly replaced and are usually less polluting. They are not the result of the burning of fossil fuels or splitting of atoms. The use of renewable energy is contributing to our energy supply. Some alternative energy sources are: biomass, geothermal, hydroelectric, solar, wind power, fuel cells, ocean thermal energy conversion, tidal energy, and wave energy. Biomass is renewable energy that is produced from organic matter. Biomass fuels include wood and forest and mill residues, animal waste, grains, agricultural crops, and aquatic plants. These materials are used as fuel to heat water for steam or processed into liquids and gases, which can be burned to do the same thing. With more use of biomass at lower production costs and better technology, the United States could generate as much as four-and-a-half times more biopower by 2020. It is estimated that biomass will have the largest increase among renewable energy sources, rising by 80 percent and reaching 65.7 billion kWh in 2020. Geothermal energy Hydroelectric (hydropower) energy employs the force of falling water to drive turbine-generators to produce electricity. Hydropower produces more electricity than any other alternative energy sources. It has been estimated that hydroelectric power will decline from 389 billion kWh in the U.S. in 1999 to 298 billion kWh in 2020. This decline is expected because most of the best sites for hydropower have already been developed and because of concerns about the adverse impact that large-scale hydroelectric facilities may have on the environment.

If the temperatures are very hot inside the efficiency rating will be very high, whereas if the temperatures outside are very hot the generator slows down. The 10kW capacity of the ORC engine is very small compared with 1,100mW, as was the capacity of a geothermal power plant in San Francisco in the year 1994. In 1996 the power plant produced 4.5 million megawatt-hours of electricity, which is enough to provide all of California with electricity. An estimate of the potential size of this energy source comes from the above value of 4.5 million megawatt-hours of electricity, which as can be seen below converts into 16,200 Giga-Joules at the Geothermal Power Plant in San Francisco.

    http://www.bbc.co.uk/climate/adaptation/geothermail_energy.shtml
    
    Extractions: There are three types of power plant that can convert geothermal energy to electricity, depending on the temperature of the geothermal fluid used. All three use a turbine that is driven by steam, which then drives a generator to produce electricity. Humans have used geothermal energy for thousands of years, using hot springs initially for cooking and building reservoirs around springs to create shrines and bathing complexes such as those built at Bath by the Romans. The dramatic rise in oil prices in the late 1970s prompted the Department of Energy in the UK to look for alternative energy sources. A number of deep geothermal aquifers were identified.

28. What Is Geothermal Energy And How Can It Be Used?
    geothermal energy is one possible (alternative) green energy source that could potentially reduce our contribution to greenhouse gas emissions.  
    http://www.geothermal.ca/whatis.html
    
    Extractions: Return to the CGEA main page. Geothermal Energy The Earth's Temperatures Geothermal Resources Geothermal Resources in Canada ... Uses - Different Kinds of Geothermal Energy Systems Energy comes in many different forms. One form of energy is heat or "thermal" energy, which can be in the form of, for example, solar energy (from the sun); thermochemical energy (heat released from chemical reactions) and radiogenic energy (produced by radioactive decay). The Earth is a storehouse of energy that is produced internally by radiogenic heat production and long-term cooling of the planet. The surface of the Earth is also warmed by solar radiation. We refer to the Earth's energy as "Geothermal Energy". This energy is available to us for use in a variety of applications, including recreational use (hotsprings), direct use for heating, and power generation. Recent public interest in geothermal energy has however led to some confusion on the different forms of geothermal energy that are related to different types of geothermal resources. A complicating factor is that different people use different terms to describe essentially the same thing. Traditionally, geothermal energy was related to high temperature resources that are needed for power generation. However, the value of lower temperature resources for direct heating or recreational use has broadened the definition of geothermal energy. Of course, with our current drilling technology, we are limited to drilling relatively shallow boreholes. For example, water wells and mining boreholes may extend to several hundred metres below ground surface, while oil wells may be considerably deeper (a few thousand metres). The deepest borehole drilled on Earth was drilled in Russia, and it extends about 12 kilometres deep. Because we can only access heat energy from the very near surface of the Earth, it is to our advantage to seek out areas that have high geothermal gradients if we are interested in high temperature resources. Alternatively, if low temperature resources are sought, the relative stability of ground temperatures beyond a few metres depth allows us to access Earth energy at a fairly constant temperature year round.

    http://csf.colorado.edu/students/Renaa.Hans/geothermal.html
    
    Extractions: Hydrothermal energy is today economic at a number of sites. It can be used to generate electricity or to produce hot water for direct use. Many countries, including the United States, Japan, France, New Zealand and Iceland and some developing countries in Latin America and Africa, are today taking advantage of this resource. However, the geothermal energy's potential as a substitute for current energy sources is much larger because of the high energy content in hot dry rocks, magma and geopressured geothermal energy. Further research and development need to be done in order to make the use of these resources economically feasible. The main advantage of the use of geothermal energy over conventional energy sources is the environmental benefits. Geothermal power plants generates just a fraction of Sulfur-, Carbon-dioxide- and Nitrogen- oxide-emissions as compared to fossil power plants. Geothermal power plants also require very little land compared to that needed by other energy sources. Geothermal plants are also modular, and can be installed in increments as needed. Geothermal energy is (very close to) renewable as opposed to fossil fuels. When geothermal energy is used to generate energy, the spent geothermal fluid is injected back into the peripheral parts of the reservoir to help maintain reservoir pressure. Because the reservoir's temperature will decrease by a very small fraction we cannot theoretically say that the energy is totally renewable. However, this temperature decrease is so small that its practically renewable. When a geothermal reservoir is used for direct-heat applications the heated water is usually fed into a heat exchanger before injected back into the earth. This water is then used for home and greenhouse heating and a variety of other uses. The consumption of groundwater is zero.

    Extractions: SEM ENERGY: Technology and Directions for the Future John R. Fanchi. Ph.D. Energy: Technology and Directions for the Future is a survey of energy sources that will be available for use in this century. It recognizes that society’s dependence on fossil energy is in a state of transition to a broader energy mix. Forecasts of the 21 st century energy mix show that a range of scenarios is possible. The more likely scenarios anticipate the use of several different energy sources. Energy professionals of the future will need to understand the origin and interactions of these energy sources to thrive in an energy industry that is evolving from an industry dominated by fossil fuels to an industry working with many energy sources. Energy: Technology and Directions for the Future is designed to help the reader understand and appreciate the role of alternative energy components in the energy mix. To achieve this objective, the reader will learn about the history and science of energy sources as well as energy technology. Material in the text is presented in a set of thematic modules (see the table below). Themes include thermodynamics, electricity distribution, geothermal energy, fossil fuels, solar energy, nuclear energy, alternative energy (wind, water, biomass, synfuels), energy and society, energy and the environment, sustainable development, the hydrogen economy, and energy forecasting. Technical strands run through the thematic modules to help prepare students for increasingly sophisticated concepts. A familiarity with the material presented in the text will help the reader better assess the viability of emerging energy technologies and the role they will play in the future.

They are located in deep sedimentary basins around the world (eg along the Gulf Coast of the United States and in Central and Southern Europe), as well as on the edges of the tectonic plates. Geothermal energy has been used by humans for many centuries in applications such as space and water heating, cooking, and medicinal bathing. The first geothermal power generation plant was constructed in 1904 in Larderello, Italy. This had a capacity of 250kW and used geothermal steam to generate electricity. The second geothermal power station built was in the 1950s at Wairakei , New Zealand. This was followed by The Geysers in California in the 1960s [3].

    By using (alternative) fuel vehicles, photovoltaic energy, and geothermal energy, DoN is promoting use of more natural, greener, and cheaper power.  
    http://web.dandp.com/n45/doc/navydocs/page16.html
    
    Extractions: Finding and using environmentally friendlier energy and fuel sources has been a DoN focus for many years. By using alternative fuel vehicles, photovoltaic energy, and geothermal energy, DoN is promoting use of more natural, "greener," and cheaper power. DoN is a leader in the AFV effort. In March 1995, DoN operated 700 vehicles that run on clean-burning natural gas, with another 1,000 vehicles planned for conversion in 1995. DoN is working with local gas companies to provide the necessary "filling stations" and is making those stations available to the public. It costs about $5000 to convert a vehicle to use compressed natural gas (CNG), but that cost is expected to be recovered during the 7 year average service life of each vehicle in lower fuel costs. Natural gas vehicles (NGVs), in addition to reducing air pollution, have longer lasting engines, burn higher octane fuel for better performance, and reduce dependence on foreign petroleum. The savings in mobile emission reduction credit per vehicle provide another incentive for their use. (Center) This PV system in Bermuda has been providing electric power for a decade.

    Extractions: Energy comes in many different forms heat (thermal energy), light (radiant energy), mechanical, electrical, chemical, and nuclear energy. All forms of energy are stored in different ways. These sources are divided into two groups renewable (an energy source that we can use over and over again) and nonrenewable (an energy source that we are using up and cannot recreate in a short period of time.) Renewable and Non-renewable Energy from the Energy Information Administration Today we get most of our energy from NONRENEWABLE ENERGY sources. These include the fossil fuels oil, natural gas, coal, and nuclear energy. Fossil fuels were formed over millions of years by heat from the Earth's core and pressure from rock and soil on the remains of dead plants and animals. Another nonrenewable energy source is the element uranium. Through a process of nuclear fission we split uranium's atoms to create the heat used to make electricity.

    Extractions: Low and High Density Alternative Sources of Energy: a Categorization We can use the traditional `elements' to categorize the types of modern `alternative sources of energy'. I find this a useful aid to memory. Most of the energy sources that come under the rubric of the traditional four elements depend on low density transformations. This means they are expensive: Aristotle's fifth element can represent a `high density' transformation, nuclear energy: Like the other alternative sources of energy, nuclear energy is expensive, but for different reasons. All kinds of alternative source are examples of high initial cost development ; they will only become widespread with low incremental costs. Let's look at each element in turn: Earth is for biological, self-replicating sources, such as wood or sawdust from trees, oils used in cooking and then for diesel fuel, and ethanol from biomass. In addition, Earth is for geothermal energy sources, both those which occur in certain places, such as Iceland, and those which might be tapped by drilling deep enough. (Geothermal energy may be concentrated: a `high density' source, but readily accessible geothermal energy is rare.) The European Union could pay for growing biomass in its new members. This would enable the Union to sidestep the Common Agricultural Policy, which is no longer useful, enable richer countries to transfer money to poorer ones, and help reduce net carbon emissions.
