Describe this alternative resource.

Hydro energy can be defined simply as using the energy of flowing water to generate power. With early man, this power was experienced in the form of propulsion as in moving wheels to grind food materials. With modern man, hydro energy is used to power turbines that produce electricity. In cases such as the Three Gorges Dam in China, hydro energy can be the basis of providing huge amounts of energy to countries in need.Press here for link page to see a hydroeletric dam loos like and a generator here.

Describe the process used to transform this energy into electrical energy.

Here are some ways to turn hydroelectric to electrical energy. A hydroelectric power plant harnesses the energy found in moving or still water and converts it into electricity. That current is then sent by means of power lines to the public as electricity. The dam is usually built on a large river that has a drop in elevation, so as to use the forces of gravity to aid in the process of creating electricity.

Describe the advantages of using this resource instead of burning fossil fuels.

Hydroelectric power plants use the resources that are readily available to us and do not create pollution. They are excellent learning devices; they teach us about energy in its different forms.
  • 1882 - World's first hydro energy power plant goes into operation on the Fox River in Appleton, Wisconsin.
  • 1886 - 45 hydro energy electric plants exist in the U.S. and Canada.
  • 1889 - Two hundred electric plants in the U.S. use waterpower for some or all generation
  • 1907 - Hydro energy provides 15% of all electricity in the United States.
  • 1920 - Hydro energy provided 25% of all electricity in the United States.
  • 1937 - Bonneville Dam, first Federal dam, begins hydro energy production on the Columbia River.
  • 1940 - Hydro energy provided 40% of electrical generation in the United States.
  • 2003 - About 10% of U.S. electricity comes from hydro energy as population growth, increased power needs and environmental issues reduce reliance on hydro energy.

Describe the disadvantages of using this resource.

Some disadvantages are:

Smaller models depend on availability of fast flowing streams or rivers
Run-of-the-River plants can impact the mobility of fish and other riverlife. NOTE: Building a fish ladder can lessen this negative aspect of hydroelectric power.
Hydro energy can be defined simply as using the energy of flowing water to generate power. With early man, this power was experienced in the form of propulsion as in moving wheels to grind food materials. With modern man, hydro energy is used to power turbines that produce electricity


Describe how this energy relates to your everyday life.

    • Inexhaustible fuel source
    • Minimal environmental impact
    • Viable source--relatively useful levels of energy production
    • Can be used throughout the world

You can fun play games, wacth videos, and learn more at this site here. Here are some funny cartoons to see,a cool diagram,and a map of how much the US used Hydroelectric Power Water in 1990. Heres a cool video of water coming out of the dam click here.
