GEO 100: 2nd Writing Assignment May 3rd 2012 Human Impact on Water Water is something we use every day. We drink it‚ brush our teeth with it‚ shower with is and lots of other things. Yet it is the one thing we think about the least but we have a huge impact on it. We waster lots of water every day and let nasty chemical get into the rivers and streams from which we get our water. Things we do in our everyday lives may seem as it is un-harmful‚ but not only are we harming the water quality

nuclear power plants and hydroelectric dams provide about 50% of the power generated for the United States doing so in a clean and efficient manner. Both systems have their ups and down‚ radiation and disrupting ecosystems for example‚ but their benefits far outweigh the small risks and problems they create. We have progressed in leaps and bounds in power development making these two much safer and efficient than most other ways to generate electricity. Hydroelectric dams create a substantial amount

What it did was controlled the flow of the water in the colorado river so that anything downstream there would be no crazy flooding which was exactly what the Yuma valley

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
