Abstract
This paper analyzes hydropower which is a form of energy obtained from flowing water. Hydropower has been in existence for over 2000 years when the Greek first powered a clock using water around 250 BC. The writer of this paper focuses on Hydro-Quebec, the largest source of hydropower in Quebec and argues that this renewable energy source is an environmentally-hazardous option.
From the Paper
"Furthermore, Hydro-Quebec has also been active in diverse areas of the world, forming partnerships with US power plants and investing in hydropower efforts in Senegal and Vietnam. Although the company's promotional literature claims that Hydro-Quebec is committed to environment-friendly processes, the fact that the potential damage of hydropower is not yet known threatens the credibility of Hydro-Quebec's claim. Indeed, although such organizations as Greenpeace Canada prefer the use of hydropower, as provided by Hydro-Quebec and similar firms across Canada."

From the Paper
"Water has been used to generate power for thousands of years. The use of water to generate electricity is a relatively new phenomenon, but one which has gained in popularity since such power is renewable and often readily available. This research explores the use and production of hydropower in Canada, with a special emphasis on the James Bay construction project. Attention is given to hydropower itself, different types of hydropower projects, and the economic, environmental and social costs associated with large hydropower megaprojects.
Hydroelectric power comes about when water passes through a vertical distance (called a 'head'). "Run-of-the-river" techniques use the head from the increased flow from a gradually declining riverbed. Dams use falling water which..."

Abstract
This paper discusses how concrete gravity dams are effective in most part due to their extreme size and weight, which counters all external forces, and how, used for many things, dams such as these can generate enormous amounts of hydropower and create massive reservoirs when necessary. Although dams do pose a certain amount of risk on the environment and those living around them, the positive aspects of dams seem to outweigh this risk.This paper explores the design behind concrete gravity dams, including but not limited to hydropower uses, effective external and internal forces, dam site selection, and many other related topics.
From the Paper
"Throughout the history of dams, many failures have been attributed to weaknesses in the concrete used in the construction of the dam. Because the concrete is the main component in most large dams, it is important that it meets certain standards. Concrete is susceptible to deterioration, especially if it is constantly freezing and thawing (Jansen 109). It is important, when designing a concrete gravity dam, to recognize that the concrete will become saturated over time. When the Saint Francis Dam collapsed in 1928 less than two years after it had been built, it was found that the engineers had not implemented into the design the idea that the concrete would become saturated and therefore become less effective. For this reason, among others, the resultant vector of the forces acting on the dam was misplaced (outside of the middle third of the foot) and the dam eventually collapsed (Jansen 181). In later investigations, the concrete was also found to have a void ratio of 14%, which would increase the degree of saturation (Jansen 179). "

From the Paper
"Alternatives: The drawbacks in bio diesels made environmentalist concentrate on cheap and easy to make eco fuels. Eco- fuels are touted as the free energy that is not only renewable but is also harmless for the environment as they do not cause any emissions. These eco fuels can generally be made and stored at home meaning that consumer just by incurring some cost on machines and systems can fulfill their energy needs. Today technology can be used to make convert simple products like turds into methane. Some of these technologies require only some efforts on consumers' parts as they are mostly do-it-yourself ventures. There are methods available that make use of hydrogen per oxide to increase the fuel efficiency of the engines of the vehicles. Not only vehicles can be run but using these eco fuels home heating and cooling and power production can also be done. Even alcohol can be used to heat up homes and to cook food. There are organizations and individuals working for the cause and they have developed different easy to implement techniques and methods to use cheap and easily available materials to fulfill different energy needs."

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
This research discusses the world?s current energy crisis. Fossil energy comprises the majority of the world?s energy source; however, these fuels pose threats to the environment and do not provide a renewable source of energy. Analysts predict that the world will run out of fossil fuels in forty to fifty years. Due to this impending crisis, experts research and attempt to determine renewable energy sources that meet the world?s growing energy needs while considering the technical, environmental, financial, and social impact of these alternatives. This report summarizes four of the most developed renewable energy options that could feasibly replace fossil fuels as a source of energy, including fuel cells, solar power, wind power, and hydroelectric power. Fuel cells use substances such as methanol and oxygen to react and provide energy; however, obtaining a clean, reliable hydrogen source and lowering the cost must precede implementation. Solar power harnesses the sun?s thermal with photovoltaic cells to produce electricity; the paper focuses on concentrating solar technologies and the addition research required to employ this alternative fuel source. Wind power uses turbines situated in a field to capture the kinetic energy of the wind; as one of the most frequently used renewable energy resources, this solution may become feasible as prices decrease. Hydropower uses flowing water through a system of turbines and generators to produce vast amounts of clean energy, but its environmental impacts are serious and widespread. All of these renewable energy sources have advantages and disadvantages when it comes to producing energy on a large scale. Some of these factors include cost, efficiency, environmental factors, and political and social factors. The report recommends an increase in research for each of these fields, and concludes that these renewable energy sources will only develop if society as a whole accepts the financial burden that accompanies them. Overall, the financial burden of renewable resources does not compare to the devastating effects that continued fossil energy usage will leave on the environment.
From the Paper
"As the global energy crisis worsens, scientists and researchers internationally race to refine and implement renewable energy resources to provide societies basic power needs that do not depend upon the consumption of natural resources. Within the next century, if energy consumers continue to rely on resources such as coal, petroleum, and other fossil fuels at the current rate, society will deplete its fuel reserves, specifically petroleum, to the extent that alternate power sources become necessary to maintain current standards of living based on power sources. Environmentalists, scientists, and the general public target fossil fuel usage as the primary cause for the environment?s poor condition; renewable resources will offer an opportunity to prevent and possibly improve damage caused by pollution from power procurement. Globally, consumers are ill-prepared for our inevitable reliance upon renewable energy resources; moreover, developing countries in the process of electrifying their citizens will not have the means to progress in the same energy-technology development cycle and cannot base their tenuous energy dependence on a rapidly waning fuel source. In the absence of fossil fuels, people must rely on new forms of transportation and energy to power our increasingly
technology-based society. Renewable resources, such as fuel cells, solar power, wind power, and hydro power offers an environmentally-savvy alternative to fossil fuels, yet many of these technologies require further research, refinement, and optimization before we can rely upon them as a substitute for fossil fuels in basic power needs (SolarPACES 1). The problem involves ensuring global preparedness when low energy reserves mandate the use of renewable energy resources through proper allocation of renewable energy technology, ethical support from the public and the government, financial flexibility, and environmental sustainability."

Abstract
The Three Gorges Dam project, if completed, would be the biggest construction in the history of the world. The project will be the largest hydropower station and dam. There is a growing concern both domestically and internationally about the human rights violations associated with the displacement of people. This paper discusses why the construction of the Three Gorges Dam is a mistake and gives possible solutions in its stead.
From the Paper
"The Peoples Republic of China has undertaken the greatest project since the building of the Great Wall and the Grand Canal. The Three Gorges Dam project, if completed would be the biggest construction in the history of the world. The project will be the largest hydropower station and dam. The project has been controversial since it was first proposed and construction has been stopped several times. There is a growing concern both domestically and internationally about the human rights violations associated with the displacement of people. An estimated 2 million people will lose their homes, livelihoods and their land. The project will create millions of refugees, flood homes and cultural treasures and endanger human health [Marcia & Joseph 1998].
The massive Three Gorges Dam on the Yangtze River in China will have a 1.2-mile stretch of concrete and a 370 mile-long reservoir, which would be 525 feet deep. The project will stretch two kilometers across the Yangtze River, stand 185 meters high, and create a 600-kilometer lake behind it. Indeed it will be one of the monstrous erections in the world. This project will cost more than any other single construction project in history with an unofficial estimate as high as USD 75 billion or more. Construction of the dam began in 1994 and is scheduled to take 20 years and yet another $24 billion. Much of what the project opponents both inside China and around the forecasted in 1989 is in full view for the world to see [Marcia & Joseph 1998]."
