Best Answer

Hydroelectric power has been touted as the 'environmentally clean, renewable source of power.' This is subject to debate, as hydroelectric dams use turbines to generate electricity, and these turbines are spun by shafts which have blades on them. Fish which get caught in the high-pressure streams of water directed at the turbine blades usually do not survive the encounter with the blades. Also, the impoundments, or lakes, behind hydroelectric dams slow the speed of the river so much that many young fish do not survive the long swim to the ocean, where food is plentiful in comparison to rivers. Of course, dams present a complete barrior to upstream migration, unless fish ladders are in place, and even fish ladders are not 100 percent effective, as many fish are unable to locate the ladders. Salmon populations upstream of Grand Coulee Dam, which does not have fish ladders, disappeared, except for the freshwater varieties.

Is hydroelectric energy costly?

Hydroelectric energy can vary in cost depending on factors such as the size of the project, location, and infrastructure requirements. While the initial costs of building a hydroelectric plant can be significant, the operating and maintenance costs are generally low compared to other energy sources over the long term. Additionally, once the plant is up and running, hydroelectric energy can provide a reliable and sustainable source of power.

How energy lost by hydroelectric?

Energy is lost in hydroelectric power generation through factors such as friction in turbines, resistance in transmission lines, and inefficiencies in the conversion of kinetic energy into electrical energy. These losses reduce the overall efficiency of hydroelectric power plants.
