Hydroelectric Power I:

Hoover Dam
Historical Growth of Hydroelectric power:

Currently Hydro power is 7% of the total US Energy Budget. This has been going decreasing with time
This varies considerably with region in the US due to the availability of freely flowing streams
Dam building really was initiated in the 1930's as part of a public works program to combat the depression
Low cost per KWH (see below) caused exponential increase of dam building from 1950-1970 (lots of this on the Columbia)
Since 1970 hydroproduction has levelled off and therefore becomes an increasingly smaller percentage of the US energy budget.
