Abstract
The paper explains that geothermal energy refers to energy that comes from the earth's hot core up to the surface, and the origin of this energy is the magma and other super-hot material several miles below the surface of the earth. the paper relates that it is a renewable and sustainable source of energy, geothermal energy will be present for the entire life of the earth, and extracting it does not pose any threat to the environment. Also, the paper relates that the energy itself is only heat; it is not highly radioactive or in any other way dangerous to living things. This paper explains the heating and air conditioning functions of geothermal energy, firstly by discussing plants, then by discussing heating and cooling more specifically. The paper concludes by analyzing the future of geothermal energy given the state of the world economy and our engineering knowledge.

Abstract
The paper discusses how geothermal energy is the cheapest, most efficient, safest method of power production. The paper reveals that in use for over 100 years, it is a proven technology that does not pollute, alter the environment, take up space or endanger neighbors. The paper outlines two different varieties of geothermal energy.

From the Paper
"Recently at the United Nations, scientists submitted a report on global warming. It contained dire predictions of climate change if the amount of carbon emitted into the atmosphere is not curtailed (Alley, et. al. 2007). It is believed that China will soon pass the United States as the world's biggest contributor of carbon emissions, due to her expanding reliance on coal. Clearly the world needs more energy, particularly developing nations like China. But where are we to get this energy? What is the cheapest, safest and most efficient method available? Of the many alternatives to fossil fuels, the most reliable,..."

Abstract
This paper discusses the earth's geothermal energy. The paper contends that geothermal energy cannot be trusted to supply all of the world's energy needs as there are simply not enough geothermal reservoirs near the surface of the earth. The paper explores the optimism expressed by some geologists who believe that, as drilling technology improves, humans will be able to reach enough geothermal reservoirs to accommodate a large percentage of the world's energy demands.

From the Paper
"The earth formed approximately 4.5 billion years ago. Our planet's geothermal heat originates from the energetic remnants of that coalescence. Over time, the interior of the earth "became differentiated into several distinct compositional zones: a large, iron rich core; a thick surrounding mantle; and at the surface, a thin, low density crust". (Montgomery 10). This fact contributed to a number of important attributes of the earth, including the formation of the atmosphere which came into existence thanks to gases escaping from the hot interior."

Abstract
The paper relates that geothermal power is safe, efficient, a proven technology and does not pollute, add to global warming or involve great expense. The paper explains that the main shortfall is only that geothermal resources are not available everywhere. The paper also points out that promoting geothermal plants in countries like North Korea or Iran could help control the arms race by offering alternatives to nuclear power.

"Today geothermal energy is the primary source of power in Iceland, providing a majority of the needs for the capital Reykjavik, a modern city of 300,000 people located in a very cold climate. Geothermal energy is still used in Italy and its use has increased steadily in New Zealand, California and Japan. It has also grown steadily as a source of energy for Third World or developing economies as well, representing 27% of the total electricity generated in the Philippines, 12.4% in Kenya, and 11.4% in Costa Rica. (Dickson and Fanelli, 2007)."

Abstract
This paper takes a look at the uses of geothermal energy, how it is harnessed, which countries presently use this form of energy, the different types of geothermal reservoirs, and the different processes used for generating power through geothermal energy.

From the Paper
"According to Godfrey Boyle, geothermal energy "is the natural, internal heat of the earth that is trapped in rock formations deep within the crust, but only a fraction of this vast storehouse of energy can be extracted" (1996, 128), meaning that the sources for this type of renewable energy are not found widely on the earth. Historically, geothermal energy has been used by various cultures and countries for hundreds or perhaps thousands of years, especially in areas where hot springs, geysers and other volcanic activity is widespread. One such country that uses geothermal energy on a daily basis is Iceland, located on the Mid-Atlantic Ridge and just south of the Arctic Circle. In Reykjavik, the capital city of Iceland, many modern buildings, such as schools, factories and private homes, are heated by geothermal energy which rises to the surface through hot springs which can be found scattered all over the island."

Abstract
Geothermal energy is described as the natural, internal heat of the earth that is trapped in rock formations deep within the crust, but only a fraction of this vast storehouse of energy can be extracted. The paper looks at the way this energy source is used and the limitations of its widespread use.

From the Paper
"In recent years, the use of geothermal or natural steam power has greatly advanced. Deep wells have been driven at the Geysers region in northern California where the capacity has been estimated to be over 400,000 kilowatts. In addition, the use of geothermal steam power has been used to some extent in New Zealand, Japan, Mexico and Italy where recent efforts have been made to develop geothermal power as an alternative to burning fossil fuels, due to the fact that geothermal power is extremely clean and moderately cheap to harness."

Abstract
This paper assesses the costs and benefits to the environment of using nuclear energy. The paper explains that while theoretically nuclear energy is a clean, effective, efficient and almost inexhaustible form of power, public opinion is widely opposed to its usage. However, the author of this paper maintains that that opposition is based on misinformation. The paper explains the process of creating and harnessing nuclear energy, showing how it is nearly identical -- save the source of the heat -- to that used by geothermal energy plants and many coal-burning plants. The paper further demonstrates that nuclear energy is actually the safest, most environmentally-sound energy option and concludes that more should be done to support its adoption as America's primary sustainable energy source.

From the Paper
"The public's apprehensive assessment of nuclear power remains its most serious obstacle. Although disasters and fatalities have been fairly limited, the potential for catastrophe is not overlooked by anyone. The Three Mile Island disaster seems to be burned into public perception regarding any discussion of nuclear energy (Beder, 224-5). Additionally, radioactive nuclear waste cannot be dumped back into the environment: it remains dangerous for thousands of years. As a consequence, collecting, relocating, and storing this waste presents environmental risks that most other energy resources are not associated with. Naturally, if proper precautions are taken and no mishaps occur; nuclear power is perhaps the most cost effective, cleanest, safest, and sustainable form of energy society has to offer. However, all rests upon its appropriate handling and the public's trust in its distributors."

Abstract
This paper examines how energy is the vital force powering business, manufacturing, and the transportation of goods and services to serve the American and world economies and how, if we don't do something, there could be a problem. It looks at how we can't continue to rely on fossil fuels as we do today because of their limited supplies and how we need to find new, renewable, and alternative energy sources. It analyzes the technologies, such as hydropower, hydrogen and fuel cells, geothermal, and biomass, and shows how we need to decide what we are going to do to change our ways and help preserve the world we love.

From the Paper
"The last predominate renewable energy source is from water or what is called hydropower. We can harness one of the earth's most predominate resources to our advantage and create clean renewable energy. According to the Alternative Energy Institute, "There are several favorable features of hydropower. Anywhere sufficient rain falls, there will be rivers. If a particular section of river has the right terrain to form a reservoir, it may be suitable for dam construction. Once the system has been installed, no fossil fuels are required to produce the electricity, and the earth's hydrologic cycle naturally replenishes the "fuel" supply (Alternative Energy Institute)."

Abstract
In this paper the author examines the sources available to create power and electricity. He looks at how technology is used to take advantage of the forces of nature available. The paper highlights how up until recently only the power created by falling water has been explored and used successfully in a number of applications. Sun, wind, waves, rivers, tides and the heat from radioactive decay in the earth's core are all looked at as being renewables, in other words they give continuous sources. The paper concludes with a look at all of the environmental aspects of using these renewable sources, the arguments for and against each one including the aesthetic issues that arise. Introduction Solar Energy Wind Energy Rivers Geothermal Relating Renewable to Base-Load Electricity Demand Environmental Aspects

From the Paper
"The main role of solar energy in the future will be that of direct heating. Much of our energy need is for heat below 60oC - e.g. in hot water systems. A lot more, particularly in industry, is for heat in the range 60 - 110oC. [2] Together these may account for a significant proportion of primary energy use in industrialized nations. The first need is readily supplied by solar power much of the time in some places and the second application commercially is probably not far off."

Abstract
This paper discusses the energy policy of President Jimmy Carter. It examines environmental awareness in the 1970s, including the first earthy-crunchies (also called tree-huggers) and the establishment of Earth Day. The paper also lists Carter's achievements in getting legislation passed to both inhibit use of increasingly scarce fossil fuels and to develop alternative energy sources. Finally, the paper discusses Carter's failure to recognize true alternative power sources.

From the Paper
"It is difficult to understand why Mr. Carter places more emphasis on synthetics than on solar energy. In the 1970s, arguably, the oil interests were not quite as entrenched in American government as now (certainly not in Mr. Carter's circle, it would seem), and solar energy was a darling of mass market publications, such as Mother Earth News; it was a favored subject of the earthy-crunchies, if overheard discussions of Baby Boomer Americans can be believed. But, the paucity of governmental support, financial and otherwise, for solar energy had made it likely that technology is not much more advanced than it was in the 1970s, indeed, building a 'green house' relying on solar energy is more expensive even now than conventional construction."
