Hydroelectric power is a form of sustainable energy that is produced by harnessing the power of flowing water. The power is generated by channeling the flow through a turbine which rotates a generator and creates the power. The most common location for instillation of a hydroelectric power plant is at a dam. The water develops potential energy while it is stored in the reservoir behind the dam and is then gravity feed through extremely large steel pipes into the turbine. The pipes used are referred

The Hoover Dam Hoover Dam‚ also known as Boulder Dam‚ is a concrete dam built in the Black Canyon of the Colorado River. It was built on the border between the states of Arizona and Nevada and it also crosses the border between two time zones‚ the Pacific Time Zone and the Mountain Time Zone. When it was completed in 1935‚ it was the world ’s largest electric power producing facility and the world ’s largest concrete structure. The dam is located about 30 miles southeast of Las Vegas. It is named

The Effect of Dams on Reservoir Sedimentation and Environmental Flow A dam is a barrier‚ obstruction or blockade built for the sole purpose of storing water. There are many uses for these systems‚ including its combination with hydropower‚ and the re-distribution of the deposited water. The benefits of the dam are very valuable to everyday life. They provide flood control‚ water supply‚ fishing hydroelectric power‚ recreation and more. But just as we figure out how to improve energy efficiency

vectors. Transgenic salmon are currently being reviewed by the FDA as being the first approved transgenic animal to be publicly available for consumption. Reasons why transgenic salmon are on the cusp of approval is to address over fishing issues and due to the main current source of salmon (Atlantic salmon) being classified as an endangered species. Genetically modified salmon have been modified by integrating the growth hormone regulating gene from Atlantic Chinook salmon in conjunction with an

Energy resources have had a widespread effect on everyday lives across the nation. Day by day from sunup to sundown about 30 percent of the world’s energy is being used by the United States. Ideally energy comes from the burning of fossil fuels and oils imported from across the globe. However‚ there has been various disputes on how the United States could find alternative energy sources for widespread use. Alternative energy is any form of energy used that is not fossil fuel that come from energy

Salmon Mommas Ten years ago‚ there was an old documentary named Glaciers -- Alaska’s Rivers of Ice which gave us a brief view of salmon. Salmon are a very famous anadromous migratory fish‚ which spawn in freshwater rivers‚ postpartum back in the ocean of fattening. The young fish will live in fresh water for 2 or 3 years‚ and then they swim into the sea‚ where staying a year or years until sexual maturity. After that‚ they return to the original birthplace to spawn. After ten years‚ now‚ just as

Summary The project of constructing the Hoover Dam was not an overnight decision‚ the first actions taken to control the Colorado River was in 1902 when then President Theodore Roosevelt the 26th President of the United States signed the Reclamation Act. Reclamation engineers began their long series of investigations and reports on control and use of the Colorado River. Over the next thirty years the unpredictability of the Colorado was evident all through the southwest‚ the Imperial Valley located

Salmon Population Restoration Salmon populations are a species indicator for their ecosystem‚ meaning the health of their population also indicates the health of their ecosystems. Factors facilitating this notion include‚ that salmon are andromodus and inhabit the entire river ecosystem‚ from headwaters to the ocean. They are also extremely sensitive to changes in the ecosystem. Variables like water quality‚ trophic webs and upstream perturbations‚ turbidity and temperature all affect the salmon
