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
it gives us power without coal or anything harmful so it's ecofriendly
Hydroelectricity is useful because it depends on the flow of water down a gravity gradient. Since water is a renewable resource (what we use, we expell and it gets reuse again) is is a much more important source of energy than petrolium products. It also provides more energy per cost ratio than does the "limitless" resources of the Sun.

chicken
How is hydroelectricity applied?
it is used to provide energy or electricity.
Can hydroelectricity be used in peoples homes right now?
It can and is. In my country (Faroe Islands) , whole villages are being powered by hydroelectricity. I've never heard of a house having a private generator, though, if that's what you're asking.
What machines are used for hydroelectricity?
The primary machine used in hydro-electric power generation is the turbine. It's a main fixture of hydro dams.
Is hydroelectricity a clean source of energy?
yes
What are the common uses of hydroelectricity?
hydroelectricity is used to create electricity.
When was hydroelectricity first used and where?
hydroelectricity was first used in 1878 in a goldfield. the inventors name is Lester Pelton.
Where is Hydroelectricity used in Canada?

Why can Iceland use hydroelectricity?
Iceland can use hydroelectricity because of its several mountains. This allows water to flow making streams and rivers ideal for hydroelectricity to be used.
Where is hydroelectricity used the most?
Where there are hills and mountains.
What could hydroelectricity be used for?
everything that uses electricity. hydroelectricity is the same thing as fossilfuel electricity...its just made differently
