Top best answers to the question «What is used in dams to generate electricity»
- Once a dam is built, an artificial man-made lake is created behind the dam. Electricity is produced by a device called a turbine . Turbines contain metal coils surrounded by magnets. When the magnets spin over the metal coils, electricity is produced. Turbines are located inside dams.

In big dams (like hoover or grand coulee), when the water flows through, it spins these huge magnets that creates static electricity in massive amounts that is then sent to a sub station to be processed from there.

I have innovated an alternative to turbine in conversion of potential energy of water into rotary mechanical energy which can then be used to produce electric energy througg an electric generator. Let me list few drawbacks of turbines, I though do...
To generate electricity in hydroelectric power stations; Hydropower is considered clean because it does not contribute to global warming, air pollution, acid rain, or ozone depletion. The United States is one of the largest producers of hydropower in the world, second only to Canada. Dams produce over 103,800 megawatts of renewable electricity and meet 8 to 12 percent of the Nation's power needs. Example: Itaipu Dam, a hydropower dam in Brazil, is the largest hydro-electric power station in ...
Hydroelectric dams produce electricity by using falling water to spin a turbine that is connected to a generator through a large metal shaft. The power that the generator receives from the turbine is converted into electricity and then transferred to homes and other structures through power lines. Dams are typically constructed on large rivers ...
A dam is a structure built across a stream or river to hold water back. Dams can be used to store water, control flooding, and generate electricity.
Sometimes, dams are located above generators. These dams increase the pressure and control the volume of water. They help the hydroelectric station generate more electricity. Hydroelectricity is a renewable resource. We can use the water over and over again to produce electricity. But there are some downsides to hydroelectricity, too.
What moving water can we use to make electricity? Hydropower Hydropower, or hydroenergy, is a form of renewable energy that uses the water stored in dams, as well as flowing in rivers to create electricity in hydropower plants. Can water be used as fuel? Water can’t be a fuel, just like carbon dioxide can’t be a fuel. These are combustion products. They can both be converted into fuels, or into energy carriers, but that requires additional energy inputs. (In the case of hydropower ...

Civil Engineering Dams A dam is a barrier that impounds water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect water or for storage of water which can be evenly distributed between locations. Dams generally serve the primary purpose of ...
Water flowing at a great force can also drive a turbine to generate electricity. Dams are built between the course of a river not just for storage of water, but also for the generation of electricity through turbines. These turbines are set up at the reservoir power station, and water falling from a great height is used for their rotation action, which in turn starts the generators, ultimately producing electrical energy. More than 2000 hydroelectric power plants are present in the US, and ...
This situation where “fixed quantity of water is used to generate hydro electricity” arises in very ideal situation. This should happen when a single or group of thermal power plants are able to provide all the electric energy to a locality. Plus when there is only one hydro plant working with these.
Dams act as the place where water is held back and released in a controlled manner through hydraulic turbines, enabling the mechanical energy of the water to be transformed to electrical energy. [6] Typical dams work to create a reservoir where water is stored at a given height.
They are mainly used to generate electricity , for irrigation in agriculture , for industrial purposes and navigation. Dams produces electricity when water flows through to the river below. Dams contain a device known as Turbines. The kinetic energy from water flow , is converted to mechanical energy by these turbines.
The hydraulic turbines used in hydroelectric dams create electricity by converting flowing water into mechanical energy.
These are electric turbines inside a dam. When water from the dam passes through, the turbines spin. This creates electricity. Hydroelectric power is produced as water passes through a dam, and into a river below. The more water that passes through a dam, the more energy is produced.
Hydroelectric dams are a very common form of hydroelectric generation used today and usually consists of large turbines that require a high volume of water flow. Hydroelectric dams use a reservoir of water to capture and flow water through a hydro turbine generator to create electricity.
