Hydroelectricity

Chapter Four 4. Practices in Electricity Generation from Hydropower Hydropower electricity is the product of transforming potential energy stored in water in an elevated reservoir into the kinetic energy of the running water, then mechanical energy in a rotating turbine, and finally electrical energy in an alternator or generator. Hydropower is a mature renewable power generation technology that offers two desirable characteristics in modern electricity systems: first, built-in storage that…

One of the most debated subjects this century is the policy on climate change. Specifically about how to go about decreasing one of the leading components most impacted by society, carbon emissions. Carbon dioxide is emitted through the combustion of fossil fuels, which is the main source of power for many of society’s technology and methods of transportation. Due to the increase use of these technologies, carbon dioxide in the atmosphere has increased to a dangerous level, changing Earth’s…

I’m writing about the navigation lock in the Atchafalaya River. In 1977, Sidney A. Murray Jr., the mayor of Vidalia, questioned the use of hydroelectric power to help reduce rapidly escalating electricity rates. It ended up with the construction of the world’s largest prefabricated power plant structure. Construction of the 192-megawatt, $520-million power plant began in 1985. Earlier plans allowed the foundation and associated works to be built in the dry at the actual project site, just…

The problems facing humanity today include the melting of arctic sea ice, the potential ocean stagnation, the mass displacement of humans from coastal cities, extreme droughts, to super storms. All these problems arise from global climate change stemming from the emittance of greenhouse gases. Some people believe these climate changes are not affected by human behavior, and that changes to reduce greenhouse gas emissions do not need to happen. I believe we don’t have time to wait and see if…

There are many arguments as to whether or not if hydroelectric power is a good solution. I believe it is a good solution from using fossil fuels as an energy source but there could possibly be better sources. It is more environmentally friendly than fossil fuels. Hydroelectric power does not pollute the environment however, it can have environmental impacts. Studies have shown that hydroelectric power plants can increase the amount of carbon dioxide in the atmosphere. This is believed to happen…

Hydroelectric Energy What is hydroelectric Energy? Hydroelectricity is a term that is referred to as generating electricity by Hydropower. Hydropower is a movement of water that flows downstream to create Kinetic Energy, which can be converted into electricity. Hydroelectric plants convert the energy into electricity by forcing water. The hydropower produces electric power through the use of flowing water or the gravitational force. Hydroelectricity is a renewable energy resource; for…

The world has solely relied on fossil fuels to supply us energy. Alone petroleum, coal, natural gas, and oil makes up eighty-one percent of the United States of America’s energy. If the world does not push to use alternative energy, eventually completely switching to alternative energy, leaving fossil fuels in the past, we will never stop some of the environmental problems contributed with burning fossil fuels. Some of the harsh environmental problems are air pollution, water pollution, and oil…

dams hurt more than they help, especially if the main use (80%) is only for recreation. I would like to see some of the dams dismantled in my state or see them repurposed for the use of hydroelectricity, which by the way was listed as on 4% of the dams in Santee in 2001. 80% vs 4% for recreation vs. hydroelectricity? I was confused when I read…

Conflict over Dams: Connections Between ‘The Tragedy of the Commons’ and DamNation Ben Knight’s DamNation depicts a conflict between Earth First! activists, hydroelectricity companies, Native Americans (particularly the Elwha tribe), and the federal government. The conflict is over several finite resources such as the salmon population, hydroelectric power, and ecosystem health. The purpose of this paper is to demonstrate that the conflict represented in the film is a clear example of the…
