What is hydro thermal energy kids version?
Hydrothermal energy is generated through the earth's hot water. The water is produced underground, and heated by the earth's thermal heat.
What is meant by a renewable source of energy?
Renewable source of energy means that this source is not exhaustible by its use in producing electricity or heat (steam) or mechanical energy.
An example is solar energy. Using sunlight to produce electricity through special devices, called photoelectric cells, will not exhaust sunlight coming to earth.
Fossil fuels like oil, gas, and coal are examples of nonrenewable sources of energy as they are exhausted by their use.
What are some types of renewable energy?
There are a few different types of renewable energy, the most common being solar.
solar, wind, wave, water, tidal, geothermal and maybe wood (unlikely)
Does hydroelectric power have any nonrenewable resources?
No, assuming rain goes on falling the water required will always be renewed every year
How do you get hydroelectricity?
Hydroelectricity is produced by rushing water through a turbine. The turbine spins at high speed, thus spinning the alternator to which it is connected, to create an electromotive force that is the electricity.
What energy source does a hydroelectric plant use to generate electricity?
well it has alot of things it could be so yea Laura a.k.a nenA WAS HERE=]
Is hydroelectricity renewable?
Yes hydroelectricity is renewable because it can be replaced naturally or faster than it is being used.
yes, hydroelectricity is renewable resource. Because, hydro means water in which electricity in produces with the help of running water.
Hydroelectricity is a renewable source of energy, as it made by harnessing the energy in moving water. The Niagara Falls hydroelectric power plants are good examples, existing as they are on both the American and Canadian sides of the border. The energy comes from using the great power of the falling water to turn giant turbines. These spinning turbines are connected to giant generators, and the spinning creates electricity that is put on the power grid system. As long as there is running water, there is power stored in it. An early use of the power of water was water wheels used to turn machinery.
Yes, hydroelectric is renewable because you can reuse it over and over.
it is its renewable because it uses different types of energy like water flowing and the sun and so much more if im not right please cheek something in barns n noble try getting a physical science book
What is the advantages and disadvantages of using diesel source of energy?
advantages , it costs a bit less than petrol
disavantages: burns alot
we love k.k and that does not burn any fuel
Does hydroelectric energy pollute?
While a little rust from the turbines is released it is general considered a clean source of power.
A power station (also referred to as a generating station, power plant, powerhouse or generating plant) is an industrial facility for the generation of electric power.
How can you coserve hydroelectric energy?
By building bigger reservoirs, ie storing more water, and by reducing the amount used
How is electric power generated by running water?
== == Think of an electric motor. When the power is turned on, a magnetic field is created which turns the shaft. This is entirely reversible. If you could turn a shaft fast enough artificially, you would generate electricity. This process is the concept behind hydroelectric power. Water coming through a dam turns the rotors of a massive turbine which generates power.
Moving water can be used to produce energy because potential energy can be converted into kinetic energy. Stored water is converted into kinetic energy. As the water travels, it is converted into electrical energy by having it turn a generator.
High voltage wires allow for the relatively efficient transmission of electricity over long distances. And within a particular electric grid, it isn't usually valid to say that your electricity comes from any one particular source of the several that may be connected.
However, very little electricity is transmitted across international borders, so by and large those countries which generate the most hydroelectricity are also those that use the most.
At present China's hydroelectric capacity is greater than that of any other country, and many massive projects there are yet to be completed. Canada, the USA and Russia are among the next nations in line.
to give us electricity
the best is to build a dam
Hydroelectric power is used the way all electric power is used: to light our world and run our civilization.
Hydropower is used almost exclusively in this modern age to generate electric power. There are very few grain mills using water power to turn millstones. And not too many water wheels are left that run spinning shafts off which belts are hung to turn machines like in the days of old.
Although most energy in the United States is produced by fossil-fuel and nuclear power plants, hydroelectricity is still important to the Nation, as about 7 percent of total power is produced by hydroelectric plants. Nowadays, huge power generators are http://wiki.answers.com/hyhowworks.html. Water flowing through the dams spin turbine blades (made out of metal instead of leaves) which are connected to generators. Power is produced and is sent to homes and businesses
How can hydroelectric energy be used?
by plant produced.

Four people found that useful?
1) The word "energy" is superfluous: if it's hydroelectric it's obviously electrical energy, so you need only to call it "hydroelectricity". Electricity is a form of energy.
2) How it's used: to power anything needing electricity, from factories, schools, hospitals etc, to homes and the appliances in them, including your computer or 'phone charger.
Hydroelectric energy is used in various ways. This is mainly used as a source of producing electricity as the water flows through the turbines.
OK
Hydroelctric energy, today, is used in multiple ways. The energy harnessed by the water flowing threw the dams or reservios is transported by wires to a power plant and then transfered into different forms of energy. The energy tis is used, is used for powering home, buisness, factories, and many more places.
How is hydroelectric energy generated?
Hydroelectric energy is produced by the force of falling water. The capacity to produce this energy is dependent on both the available flow and the height from which it falls. Building up behind a high dam, water accumulates potential energy. This is transformed into mechanical energy when the water rushes down the sluice and strikes the rotary blades of turbine. The turbine's rotation spins electromagnets which generate current in stationary coils of wire. Finally, the current is put through a transformer where the voltage is increased for long distance transmission over power lines.
How does a hydroelectric plant work?
Hydroelectric power, or hydroelectricity, is generated by the force of falling water. (Hydro comes from the Greek word for water.) It’s one of the cleanest sources of energy, and it’s also the most reliable and costs the least. Water is needed to run a hydroelectric power-generating unit. The water is held behind a dam, forming an artificial lake, or reservoir. The force of the water being released from the reservoir through the dam spins the blades of a giant turbine. The turbine is connected to the generator that makes electricity as it spins. After passing through the turbine, the water flows back into the river on the other side of the dam.
Electricity is produced by spinning electromagnets within a generator’s wire coil that creates a flow of electrons. To keep the electromagnets spinning, hydroelectric stations use falling water. Hydroelectric power plants convert the kinetic energy contained in falling water into electricity. The energy in flowing water is ultimately derived from the sun, and is therefore constantly being renewed. Energy contained in sunlight evaporates water from the oceans and deposits it on land in the form of rain. Differences in land elevation result in rainfall runoff, allowing some of the original solar energy to be captured as hydroelectric power. Most hydroelectric stations use either the natural drop of the river or build a dam across the river to raise the water level and provide the drop needed to create a driving force. Water at the higher level (the forebay,) goes through the intake into a pipe, called a penstock, which carries it down to the turbine. The turbine is a type of water wheel that converts the water's energy into mechanical power. The turbine is connected to a generator, and (4) when the turbine is set in motion it causes the generator to rotate, producing electricity. The falling water, having served its purpose, exits the generating station through the draft tube and the tailrace where it rejoins the river.
At Ontario Power Generation (OPG), hydroelectric generation is their lowest-cost power source, producing approximately 34 terawatt-hours in 2002. OPG operates 36 hydroelectric stations, as well as 29 small hydroelectric plants and 240 dams on 26 river systems. The smallest station has a generating capacity of just 1 megawatt; the largest more than 1,300 megawatts.
What are the costs of hydroelectric energy?
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.
