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.

What are positive and negative facts about hydroelectric power?
Hydroelectric power is a renewable energy source that offers significant advantages, such as low greenhouse gas emissions and the ability to provide a reliable and consistent energy supply. However, it can also have negative impacts, including the disruption of local ecosystems, displacement of communities due to dam construction, and potential risks of catastrophic failures. Balancing these factors is crucial for sustainable development in hydroelectric projects.
What is hydrolectic power?
Hydroelectric power is a form of renewable energy generated by harnessing the kinetic energy of flowing water, typically from rivers or dams. As water flows over turbines, it spins them to produce electricity. This process is efficient and produces minimal greenhouse gas emissions, making it a cleaner alternative to fossil fuels. Hydroelectric power is one of the most widely used forms of renewable energy worldwide.
What is gravitational energy used for?
Anything that uses the force of a falling object to do work. For example, water mills, hydroelectric power generators, pile drivers. Even a person jumping (up and) down on earth to flatten it.
What does hydoelectric power mean?
You probably mean "hydroelectric power". It basically means the production of electrical power through the use of the gravitational force of falling or flowing water. It is the most used form of renewable energy.

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.
What is hydroelectric energy or hydroelectric power?
hydroelectric energy is energy that comes from water
How much does hydroelectric energy cost per kw?
The cost of hydroelectric energy production varies greatly depending on factors such as location, size of the project, and construction costs. On average, the cost of producing hydroelectric energy can range from $0.03 to $0.09 per kWh.
Amount of hydroelectric energy is available?
amount of hydroelectric energy is available
What city runs on hydroelectric energy?
What city runs on Hydroelectric energy?
What industries rely on hydroelectric energy?
Since hydroelectric energy supplies electricity, any industry that uses electricity from a hydroelectric plant relies on this energy.
How are geothermal and hydroelectric energy similar?
they both use turbines to produce electricity
Why is hydroelectric source of energy better than fuels for generating electrical energy?
hydroelectric energy is free to the fuel fossil
How does energy move through hydroelectric energy?
energy moves through hydroelectric energy because of all the heating and the movement of the whole source
What are examples of hydroelectric energy?
A water turbine dam is an example of hydroelectric energy. Hydroelectricity is an important part of the energy mix in the world.
How is hydroelectric power is a usable energy?
hydroelectric power is an important for producing the power in the low loss of energy..energy is nothing but producing the power....so we can easily produce the power from hydroelectric power plant.
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.
