From the Paper
"Solar energy is radiation from the Sun that can produce heat, generate electricity, or cause chemical reactions. Solar energy is inexhaustible and nonpolluting, but it is not an efficient energy source, since the Earth's atmosphere absorbs or scatters over 50% of incoming solar radiation. Solar collectors collect the radiation and transfer it as heat to a carrier fluid. It can then be used for heating. Solar cells convert solar radiation directly into electricity, by means of the photoelectric effect.
Very often, there is confusion about the various methods used to harness the sun's abundant and clean energy. Energy from the sun can be categorized in two ways: in the form of heat (or thermal energy), and in the form of light energy. Solar thermal technologies use the sun's heat energy to heat substances (such as water or air) for applications such as space heating, pool heating and water heating for homes and businesses. There is a variety of products on the market that utilize thermal energy. Often the products used for this application are called solar thermal collectors and can be mounted on the roof of a building or in some other sunny location. The sun's heat can also be used to produce electricity on a large utility-scale by converting the sun's heat energy into mechanical energy. "

Abstract
Scientists, environmentalists, and advocates of cheap, clean energy often tout solar energy as the answer to the world's energy problems and the energy source of the future. This paper examines whether solar energy is, indeed, the answer and whether its use on a large-scale is practical for use in the United States. It also looks at the history and types of solar energy.
From the Paper
"In addition, creating solar power generators it is a much smaller endeavor than building power generators for neighborhoods and businesses. Solar energy is quiet, reliable, and safe, and it makes sense in a variety of situations. Because of this, many states, including New Jersey, are adopting stricter standards for utility companies concerning utilizing more solar power. A recent amendment by the New Jersey Legislature requires the state's electrical utilities to utilize solar power as a portion of their power generation."

"U.S. energy policy is a matter of ongoing concern. Our society makes use of massive amounts of energy of various types, and the need for energy is growing. Energy policy is tied to a number of other policies, from the economic to foreign affairs. The costs of energy have an impact on every aspect of society, and energy policy relates to foreign affairs in that the dependence of America on foreign energy sources creates a situation whereby the nation can be held hostage to the whims of external powers. In such an atmosphere, more and more concern has been raised that the United States discover a source of renewable energy, something that will not be depleted as will fossil fuels, something that is cleaner and safer for the environment than are fossil fuels, and something that is still economically viable, producing sufficient energy at a cost ...

Abstract
This paper discusses how the use of solar power could free us from hazardous gases emitted by fossil fuel combustion. It looks at how photovoltaic technology takes the energy of the sun and directly converts it into electricity and how PV's are found in navigational buoys, calculators, yard lights, watches, electric fencing, streetlights, and irrigation pumps. The paper contends that because energy from the sun is free and readily available unlike fossil fuels, we can set up an affordable system that will provide free electricity for our basic needs at an initial cost comparable to alternative forms of energy.
From the Paper
"A solar-thermal system collects the sun's energy and uses it to heat liquids. The heated liquid can be used to generate steam, which can then be used to turn turbines for electrical power. The steam can also be used for heat. In California, approximately 350 megawatts of power are produced by solar-thermal plants in the Mojave Desert. A well designed solar-thermal system in a home can reduce the cost of energy by as much as 85 percent and pay for itself in approximtely five years. Solar-thermal power releases no pollution and creates no waste, however in order for this system to operate, a lot of sunlight is required. "

From the Paper
"Energy is a crucial building block for civilization: Without reliable sources of power, modern technology would not exist. Reliability does not always equal availability, however, and the search for renewable or inexhaustible energy sources that also are relatively inexpensive, nonpolluting and available to everyone has become of paramount importance - enter solar energy. This alternative to fossil fuels has all of these advantages and comes in several forms and applications, adaptable to most uses, and as part of the earthos domain (rather than one person's - or one country's - oil field), it is nonmonopolistic.
Solar technology operates on different principles, depending on the type of system used. For example, active solar systems use mechanical means such as solar collectors, pumps and fans to ... "

Abstract
This paper provides a full explanation about the way in which solar energy is created. The paper looks at the process in details and then discusses what benefits solar energy may have in the future.
From the Paper
"Solar Energy comes from Solar cells which today are mostly made of silicon, one of the most common elements on Earth. The crystalline silicon solar cell was one of the first types to be developed and it is still the most common type in use today. They do not pollute the atmosphere and they leave behind no harmful waste products. Photovoltaic cells work effectively even in cloudy weather and unlike solar heaters, are more efficient at low temperatures. They do their job silently and there are no moving parts to wear out. It is no wonder that one marvels on how such a device would function. To understand how a solar cell works, it is necessary to go back to some basic atomic concepts. In the simplest model of the atom, electrons orbit a central nucleus, composed of protons and neutrons."

Abstract
This paper examines two distinct inventions: light bulbs and solar energy. First it discusses the incandescent light bulb and its inventor, Thomas Alva Edison, and explore the differences between incandescent and fluorescent light bulbs. Then the long history and increasing importance of solar power and its modern applications are discussed.
From the Paper
"On December 31st, 1879, after years of work and many experiments, Thomas Alva Edison gave the first demonstration of the incandescent light bulb at his laboratory in Menlo Park, New Jersey. He was assisted in his invention by Francis Upton, a Princeton Graduate who supplied the mathematical and theoretical expertise that Edison lacked. This invention established Edison?s reputation as the world?s greatest inventor. Before his invention, electric arc lighting was used to produce light. In this lighting system, lights were connected in a series circuit, so if one failed, the rest of the bulbs on the circuit also failed. (First Public Demonstration?)
Edison was able to spend so much time and money on the invention of the light bulb because of his reputation as an inventor. He had the support of financiers such as J.P. Morgan and the Vanderbilts. They established the Edison Light Company and loaned Edison $30,000 for research and development. (First Public Demonstration?)"

From the Paper
"It is probable to assume that one day in the near future, much of the world?s electricity will be generated by solar energy. Sunlight is decidedly advantageous over fossil fuels as an energy source in three significant ways; it is abundant, long-lasting, and nonpolluting. However, today the primary challenge with solar energy hinges upon cost effectiveness. Until solar energy can be made economical for businesses and private citizens, other fuel sources will retain the inside track that they have held for centuries.
Fortunately, solar energy technology has made great strides in recent years, culminating in buildings such as the Four Times Square Building in New York City- a building which is its own freestanding, environmentally friendly electric utility. Photovoltaic panels, gas fired absorption H-vac systems..."

Abstract
This paper explains the reasons behind the halt in nuclear power plant construction in the United States. Factors in the decline of nuclear power plants include raising costs, disposal of nuclear waste, concern for safety, declining public opinion and governmental programs and decisions not favorable to the nuclear power industry. Footnotes.
From the Paper
"After a period of rapid growth in the nuclear power industry, resulting in over a hundred nuclear power plants being constructed in the United States alone, in the early 1970?s the industry began to slow and even began to decline in the 1980?s, while the rest of the world continued to increase their nuclear industry capacity. In the mid-1970?s the Atomic Energy Commission predicated that by the year 2000 there would be more than 1,000 nuclear power plants in the United States.[1] No new nuclear power plants have been ordered in the United States since 1973 and several plants have gone off-line since.[2] Between 1990 and 1995, 20 additional nuclear power plants came online outside of the United States, with an additional 36 under construction. Furthermore, Robert Newman, the President of ABB Combustion Engineering Nuclear Systems, in a October 6, 1996 New York Times article suggested that his company had been approached by the government of China with a plan to build as many as 150 nuclear power plants over the next 40 years.[3] Currently, there are over 437 nuclear power plants operating around the world.[4] Hence, while the rest of the world is increasing their dependence on nuclear power, the question becomes, why is the Untied States making a rapid reversal in its dependence on nuclear power? Several tangible factors have been suggested: the rising costs of construction of a nuclear power plant, the increase in time that it takes to construct a nuclear power plant, the disposal of low grade and high grade nuclear waste, public safety of living near a nuclear power plant, declining public support for nuclear power, and the fear of nuclear power plants contributing to the proliferation of nuclear weapons around the world."

Abstract
The paper states that, in light of the effects of global warming,
it presents the case for alternative energy sources, which are becoming popular. both because they do not contribute greenhouse gases into the atmosphere, and also because they are less expensive for the most part than electricity produced by coal, oil and gas. The paper reviews the positives and the negatives for wind energy, and discusses in depth the reasons why solar energy and biomass energy sources are very attractive and offer consumers practical ways to spend less on heating and cooling homes.

Conclusion
From the Paper
"The Natural Resources Defense Council (NRDC), among the most visible and powerful advocacy and conservation organizations in the U.S. (www.nrdc.org), explains that currently California has the most wind power generation in America. Texas ranks second on the list of states with wind power, with "about half" of the wind plants that California has. The good news for consumers is that the cost of wind energy now is competitive with new coal-fired or gas-fired power plants, NRDC reports. Indeed the cost of wind energy has come down "85 percent in the past 20 years," according to the U.S. Department of Energy.
Wind of course is free, and it blows significantly, consistently, hard enough to turn rotors of windmills and produce reliable electricity in about one-fourth of the land area of the U.S., the UCS explains. The NRDC points out that windmills can be built "in a fraction of the time it takes to construct coal or natural gas power plants." Moreover, it takes just three to eight months for a windmill farm to "recoup its investment in building and installation" (NRDC). Why are windmill farms needed? About 68% of the energy produced in the U.S. today, the NRDC explains, comes from "burning polluting fossil fuels." Nuclear power plants and hydropower produce the rest, "with only a fraction coming from clean, renewable sources such as the wind, the sun, underground steam and biomass." But in 15 states laws have been passed that require power companies to produce "a percentage of electricity from renewable sources." In some states, like Texas for example, consumers can choose "Green Pricing" on their utility bills; that means the electricity that family uses will be exclusively from wind power, or other renewable sources. Meanwhile, in some countries, like Denmark, windmills have been put to use in massive numbers. According to the magazine www.Scandinavica.com, fully 20% of all the electricity in Denmark comes from wind energy."

Abstract
This paper discusses the energy trade in the United States. It discusses the increasing need for energy compared to the consumers' decreasing knowledge about where energy is coming from. The paper then discusses President Bush's State of the Union Address for 2006, in which he outlined his new advanced energy initiative, with the overall goal of reducing dependence upon Middle Eastern oil. It then addresses this goal to further advance the use and technology of solar and wind energy resources.
From the Paper
"Renewable energy has been used in various, yet mostly private applications for many years, with ah classic example of the farmer using a solitary windmill to provide energy to a pump that provides water to his fields or livestock or the application of several solar cells on the roofs of homes, either in remote locations where other sources of power are to expensive to obtain or in the city where the novice environmentalist wishes to "get off the grid." Yet, these applications are very limited and the much larger possible applications and the technology that drives them can be rather expensive, in comparison to other forms of energy attainment, especially with regard to initial investment. One of President Bushes stated goals is to reduce the cost of these investments through the development of less costly technologies. Though is a relatively simplistic look at the actual numbers, wind energy, on its own has increased in capacity significantly in the last few years and the same can be said of solar renewable resources."
