In hydroelectric power moving water turns spins a turbine. A shaft from that turbine sticks into a generator. That produces electricity. In a coal fired power plant coal heats water and steam from the boiling water turns a shaft that sticks into a generator. That makes electric power. Any source of power that can make a large shaft turn can produce electricity. The electricity comes out of the generator on wires. It goes to a power transformer. The transformer turns it into high voltage electricity. That way it can travel over transmission lines without losing energy. It is also called wholesale power. It is like a grocer who buys large boxes of cereal and cuts open the large cardboard boxes and then puts the family size boxes on the shelf to sell. You can not use this high voltage electricity. It is so powerful, it would cook you. It goes to a substation where it goes to another transformer. There is reduced in power to where it is safe to put in wires that run down the streets. Then it goes to another transformer where it becomes safe to put in the wires that go to your home.

∙ 9y agoGravitational potential energy of water is transformed into kinetic energy of water.
Then kinetic energy of water is transformed into rotational kinetic energy of a turbine.

What are the different kinds of power plants located at Philippines?
No nuclear ones, apart from Bataan which has never operated
How are tidal power plants similar to hydroelectric plants?
Both use the flow of water generate electricity. Hydroelectric uses the flow of water from a high point to a low point. (A damn). Tidal power uses the flow of ocean tides in and out.
What is electricity produced by flowing water?
This is called hydroelectric power, or hydro power.
Where would you locate an hydroelectric plant?
Along rivers or streams, at the foot of hills and mountains with ponds or lakes, and at the mouths of bays and inlets where there are tides. Hydroelectric plants operate on the basis of gravity moving water downward. So the requirement for hydroelectric power is water and a difference in height, altitude or depth. Most Hydroelectric plants are located on rivers and used dams to provide the difference in height. In some cases, hydro plants have been built at the foots of hills or mountains that had lakes on them at higher levels. If the difference in altitude is sufficient, a small flow and a small power plant can produce an impressive amount of power. It is possible to get hydroelectric power from the movement of water without a dam, and this is done in rivers with sufficient current, but where damming the river would be too destructive to the land or things on the land. It is also done in places with tidal flows that are sufficiently energetic. Micro-hydroelectric sites can even be small streams, if the water flow is sufficiently reliable.
Show picture of hydroelectric power plant in a diagarm form?
HYdroelectric power is pretty cool and here is a diagram:
What involve the conversion of gravitational potential energy into electric energy - wind electric generators or hydroelectric power plants?
Hydroelectric power plants convert GPE into electric energy. When the water flows from the higher point to the lower point, hydroelectric turbines convert the energy of the flowing water into energy.
What kind of power plants produce electrical energy from moving water?
Hydroelectric plants.
What is hydroenergy?
It is the energy obtained from hydroelectric power plants; on rivers, tidal, etc.
What is hydroelectric energy or hydroelectric power?
hydroelectric energy is energy that comes from water
What type of energy source provides a cheap form of power but can be harmful to fish?
Hydroelectric power plants
In hydroelectric power plants the energy from moving water is converted into electric power. What kind of energy transformation occurs when the energy is converted?
mechanical to electrical
Where is the hydroelectric power plants in India?
'Where are the hydroelectric power plants in India located?' will be a grammatically correct question, not 'where is'.
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.
What percent of canada's energy is nuclear?
About 15 percent of the energy produced in Canada is derived from nuclear power plants. In contrast, about 61 percent of the energy produced in Canada is derived from hydroelectric power plants.
What is water energy?
You're probably referring to energy generated by harvesting the flow of water via hydroelectric power plants and the such.
Why do hydroelectric power plants produce only about 3 percent of the electrical energy in the world today?
it not that efficient
What has the author Maria Gracinda C Teixeira written?
