tutorial
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

Resistivity of a material 
Electrical Conductivity and Resistivity 
Electrical resistivities The electrical resistivity or specific resistance ρ
is the resistance between the opposite faces of a metre cube of a material. The
values given below are in ohm metre units (Ω m) 
Electrical resistivity in general, electrical resistivity of
metals increases with temperature, while the resistivity of semiconductors decreases with temperature
