Transcript of Hydropower Energy

By: Matt, Morgan, and Caleb Hydropower Energy Hydropower is energy that comes from the force of water moving. Hydropower is a renewable source because snow and rainfall. History of Hydropower Where and How Hydropower is Found and Recovered Hydropower is found where ever water or other substances the contain water are located. Hydropower is recovered by going through a dam and turbines that are in the turbine. Hydropower has been used for centuries. The Greeks used water wheels to grind their wheat into flour. In the 1800's Americans used waterwheels. Also, in the 1940's, large dams were built to use for hydropower. How the Energy is Stored and Released Energy from Hydropower is stored in a reservoir where the water would be held. Hydropower energy is released ny turbines in the dam spinning and when it spins it creates electricity for people to use. Advantages and Disadvantages Advantages 5 to 10 percent of countries use hydropower electricity
20 percent of the worlds electricity is hydropowered
Free way to get electricity
Barley any polution Disadvantages Have to have water to work
High investment cost
Messes with the wildlife and fish species
Massive flood could break out if dam was to break Hydropower Electricity Economic Impacts of Hydropower There are many economic impacts of using hydroelectricity. One economic impact is that hydroelectricity is a very cheap source of electricity. It is cheaper than coal or nuclear. Hydropower are very low cost projects. Also, when a dam is built repayments are paid to the U.S. treasury. In 2010, the repayment made to the U.S. treasury was paid an estimated 800 million dollars. Environmental Impacts of Hydropower Very clean energy source
No air pollution in the making of the electricity
Disturbs the wildlife and the natural resources of the area
Roads may have to be moved when a dam is being built
Renewable source
Replenished by any type of precipitation
Hydropower dams help control the flooding in communities
For example, dams affect salmon becausewhen they travel up river the have to go through the traps in the dams to make it upstream How Energy source is Used Today Hydropower energy is used today in many ways. One way it is used is mainly to operate machinery for companies. Sometimes hydroelectricity is used to power some people's residence. 19% of the world's electricity comes from hydroelectricity Future of Hydropower The future of hydropower is very complicated. The capabilities of hydroelectricity are really maxed out at this time. Also, there are a range of large high scale hydropower construction projects in the works. The true future of hydropower worldwide depends on the scientific technological breakthroughs that scientist have. Random Facts About Hydropower There are 1,623 hydropower plants in the United States of America.
The closest hydropower plant to Henry County is Markland locks and dam.
Markland's construction began in April of 1959 and was finished in May of 1964. Credits •http://wiki.answers.com/Q/What_are_the_advantages_and_disadvantages_of_hydro-electric_power
