Hydropower Origins of Hydropower The first hydroelectric dam was built on Sept 30, 1882 in Appleton, Wisconsin. Mitchell Switalski

Gabriel Glazer What is Hydropower? Depends
on the water cycle. When the water hits the dam... Hydropower Facts Hydropower accounts for almost
7% of the US's electricity, and 60%
of renewable energy. Only a small percentage of
dams in the US produce electricity. Hydropower: Pros
and Cons Pros: Provides backup power in power outages
2003 power outage in New York. Highest efficiency out of almost all energy making options Lowest cost to generate overall Using hydropower avoids nearly 200 million metric tons of carbon pollution in the U.S. each year – equal to the output of over 38 million passenger cars. “For almost a century, hydropower has provided…low-cost, renewable and emissions-free electricity. In today’s environment – where talk centers on the need to provide clean and environmentally friendly energy – we must continue to promote and expand the use of hydropower. ”

– Rep. Doc Hastings (R-WA) Currently employs about 300,000 workers
The U.S. hydropower industry currently Cons: Environmental harm to surrounding areas Turbines kill fish in the river. Dams reduce sediment and nutriment flow downstream and reduces the temperature of the water. The creation of new dams can destroy the habitat of species, including forests. The initial cost of building
a dam is very high. Hydropower, Bakersfield, and Politics. FERC (Federal Energy Regulatory Commission)
is responsible for approving the building and use
of hydroelectric plants in the US. Thanks to FERC, hydroelectric
companies recieve tax parity for
the building of dams, though it
is half the credit available to other
energy sources Kern county actually has its own dam,
in Lake Isabella. 2000 years ago, the ancient Greeks used water wheels to grind wheat into flour! Falcons Love ! 94%! Almost every hydroelectric
method is at least 90%
efficient! 2 cents!
$$$ Effects of Gibe 3 dam in Ethiopia $$$ $$$ $$$ This dam, built upon the Fox River, supplied enough energy to power three buildings. Hydropower is a renewable energy source that uses the flow of water to generate electricity. The world's largest dam is on the Paraná River, and is called the Itaipu Dam. Built by the joint efforts of Brazil and Paraguay, the Itaipu Dam is 7,919 meters long, 196 meters high, and in 2000 it generated a world record amount of energy for a hydroelectric plant, 93,428 GWh (gigawatthours)! In 2000, Itaipu generated 20% of Brazil's Energy supply, and 94% of Paraguay's power! The act of destroying these forests can indirectly create more methane. Some countries, such as Norway, obtain almost all of their energy from hydropower. Works Cited http://www.greenandwhite.net/~tachyon/The%20History%20of%20Hydropower.htm
