Where in the united states is hydroelectric energy used?

Hydroelectric power is, of course, generated in areas that have the right sort of topography. Mountainous regions are often appropriate, because they allow for the formation of large, deep reservoirs, such that the retained water accumulates a great deal of gravitational potential energy. Naturally the large, powerful rivers of great continents have more potential for the generation of electricity than the more humble ones of, for example, Britain.

The question of where the electricity is actually used is a slightly different one. 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. Washington state uses the most hydroelectric energy within the USA, whilst the 'La Grande' facility in northern Quebec contributes to Canada's energy needs.

It should be noted, however, that when expressed as a percentage of total energy consumption, the significance of hydroelectricity within these countries diminishes.

Notable Hydroelectric Nations

Nations including Norway, Iceland, Brazil, Nepal and Tanzania come to the fore as the countries that derive the greatest proportion of their energy needs from clean, renewable hydroelectricity.

As long as its the correct voltage and frequency, you can feed it into the national grid.
