Energy sources can basically be broken into renewable and depletable sources, which ultimately originate from space and terrestrial sources, respectively. The space sources include solar and lunar origins where the latter gravitational energy results in tidal flows. The sun provides directly useable energy as well as indirectly providing hydro, wind, ocean (thermal & current), and even biomass through photosynthesis. Depletable sources include fossil fuels, nuclear, and geothermal (geothermal is depletable but not always thought of in that manner).
Energy is then applied to one of the end-use sectors or the intermediate
energy form of electricity. The end-use sectors include industrial, transportation,
residential and commercial. The DOE's Energy
Information Administration (EIA) has a nice energy
flow diagram .
