The science behind hydroelectric power includes elements of physics. Given an existing dam with a reservoir and a power station, let's follow the action. Water is allowed to build up behind a dam. This creates potential energy. Releasing the water and directing it through turbines converts the potential energy into kinetic energy. This energy, which is mechanical energy, spins the turbines. Call that the "first stage" of the process.
The turbines are coupled to generators, and the mechanical energy of the turbines is converted into electromagnetic energy in those generators. The electromagnetic energy (or just "electricity" if you prefer) is routed to a transformer bank to step it up in voltage. The higher voltages allow for less power loss during transit, and the energy is transported to points of use. There, it is stepped down to relatively "safe" voltages and routed out to electrical equipment and devices.
What else can I help you with?
How is hydroelectric energy recovered?
Hydroelectric energy is recovered by harnessing the power of flowing water to turn turbines, which are connected to generators that convert mechanical energy into electrical energy. Water is usually stored in a reservoir behind a dam and released through turbines to generate electricity as it flows downstream.
What is the ultimate source of energy in hydroelectric power station?
The ultimate source of energy in a hydroelectric power station is the gravitational potential energy of water. Water stored behind a dam has gravitational potential energy due to its elevation, which is converted to kinetic energy as it flows downhill through turbines, generating electricity in the process.
What a water able a hydroelectric dam have kinetic energy or potential energy?
A hydroelectric dam primarily harnesses potential energy from the water stored in a reservoir behind it. As the water flows through the dam and turns turbines, some of this potential energy is converted into kinetic energy, which is then transformed into electrical energy.
What sun is the driving force behind each of these kinds of energy except?
The driving force behind solar energy is the Sun. Wind energy is driven by the Sun through the uneven heating of the Earth's surface. Hydroelectric power is also indirectly derived from the Sun as it drives the water cycle which creates the rivers and reservoirs necessary for hydroelectric power generation. Biomass energy is derived from plants that have used sunlight to grow through photosynthesis.
When water held behind a dam is released potential energy is converted first to what energy?
When water held behind a dam is released, the potential energy is converted first into kinetic energy as the water flows downstream at high speed. This kinetic energy can then be harnessed by turbines to generate electricity in a hydroelectric power plant.
What are some sources of hydroelectric energy?
That would be water. Water from rivers being very popular with the hydroelectric dams. Storing its potential energy behind the dam.
What is hydroelectric energy or hydroelectric power?
hydroelectric energy is energy that comes from water
What is hydrogwe energy?
There is no such thing as "hydrogwe" energy. However "hydroelectric" energy is electricity generated from falling water (such as that held behind a dam.
How is hydroelectric energy recovered?
Hydroelectric energy is recovered by harnessing the power of flowing water to turn turbines, which are connected to generators that convert mechanical energy into electrical energy. Water is usually stored in a reservoir behind a dam and released through turbines to generate electricity as it flows downstream.
What is the science behind breaks?
The science behind BRAKES is that you use friction to convert kinetic (moving) energy into heat energy to stop a vehicle.
How does energy change forms as it goes from behind a dam to downstream of a dam?
potential energy that converts to kinetic energy
What is the difference between hydroelectricity and thermal electricity?
Hydroelectric energy uses water. Thermal energy uses heat. Simple Science! Duh!
Amount of hydroelectric energy is available?
amount of hydroelectric energy is available
What city runs on hydroelectric energy?
What city runs on Hydroelectric energy?
Does hydroelectric power uses heat from hot rocks?
No hydroelectric uses water, usually stored behind a dam to drive a turbine. The hot rocks you speak of is geothermal energy. The most prolific use of geothermal energy is in Iceland.
What industries rely on hydroelectric energy?
Since hydroelectric energy supplies electricity, any industry that uses electricity from a hydroelectric plant relies on this energy.
What is the ultimate source of energy in hydroelectric power station?
The ultimate source of energy in a hydroelectric power station is the gravitational potential energy of water. Water stored behind a dam has gravitational potential energy due to its elevation, which is converted to kinetic energy as it flows downhill through turbines, generating electricity in the process.
