Yes and no, they provide a plentiful source of clean energy, however, they also have a profound impact on local wildlife. Many fish species would not be able to reach the breeding grounds they go to every year, and some organisms would also die when a lake is created. In my opinion, the energy provided justifies the damage, as beyond construction, no CO2 is emitted.
how tall is the model
Is the Hoover Dam's cement still curing?
No. It was poured in 25 foot rectangular blocks, so each block would cure before pouring the next.
What are advantages and disadvantages of tehri dam?
The advantages of tehri dam is to provide electricity & hydel energy [generating electricity when water falls from a height].
The disadvantages are visible that lakhs of people houses were submerged in the making of dams there lands all the things .,the property submerged in the water. They are roaming here & there the government only decide to give money but never do this. you asked a question but now i am asking all the Indians , government ,this question are all the people are happy as they were in there old lands..................................................................
How does energy change forms as it goes from behind a dam to downstream of a dam?
potential energy that converts to kinetic energy
Humans build dams primarily for flood control and for the generation of power. As a side benefit they create lakes. Dams also can provide more workers and a better habitat for blad eagles during the winter.

Which dam is the tallest dam in the US?
Oroville Dam is currently (as of September 28th, 2010) the tallest dam, standing at 770 feet (230 meters) tall. It is currently the 23rd tallest dam in the world, and stands along the Feather River. Its name is derived from the proximity to Oroville, California, and is a major source of power for the area.
Where was the glen canyon dam located?
The Glen Canyon was built in 1956 and opened at 1966. Happy to help! :) -Anonymous
built betweeen 1931 and 1936 by the us bareau of reclamation of the colorado river between nevada and arizona. the hoover dam was one of the major public works projects of the great deppression and new deal era.
How much energy does the 3 gorges dam produce?
10% of China's energy. The main generators weigh about 6,000 tonnes each and are designed to produce more than 700 MW of power.
It will have 32 generators: 30 main generators, each with a capacity of 700 MW, and two plant power generators, each with capacity of 50 MW. Among those 32 main generators, 14 are installed in the north side of the dam, 12 in the south side, and the remaining six in the underground power plant in the mountain south of the dam. The expected annual electricity generation will be over 100 TWh, 18% more than the originally predicted 84.7 TWh, resulting from the six generators added in 2002.
What are the negative and positive impacts of the Hoover Dam?
Hoover Dam construction put many laborers to work for relatively good wages during the Great Depression. The power and water from the project created additional opportunities for growth in southern Nevada, southern California, and eventually central Arizona. Control of the water allowed production of great crops in deserts from the Imperial Valley to near Phoenix. Lake Mead provides extensive flatwater recreation opportunities in a dry landscape. Problems occurred with eventual overuse of the water from the Colorado River among the states in the basin, along with controversies for allocation of the water that continue to grow today. Ecological effects of the dams and diversions include changing the flow so that the river no longer flows into Mexico, the water temperature is lower which affects certain native fish, and quagga mussels have invaded Lake Mead and clog water distribution facilities. Lake Mead elevation has dropped to the extent that some marinas have closed. Sediment is filling the Lake Mead bottom at an alarming rate, despite Glen Canyon Dam catching some sediment about 270 miles upstream, and the first 10 miles of the reservoir below the Grand Canyon are mostly filled with sediment already. Las Vegas has recently sought water from underground basins in eastern Nevada to fill projected future demands from the city's growth beyond what is now expected from Lake Mead.
Built dams for flood control and hydroelectric power during depression?
dams were actually built in Ancient Mesoptamia. i dont know the time though.
