Alternate Sources are unconventional sources of power currently under development which tap energy sources other than fossil and nuclear fission fuels and due to the reduced availability of hydroelectric power sites. It also include other physical and chemical means of deriving electric power from new or improved materials, reactions, and conversion schemes.
