Energy | Definition, Types, Examples, & Facts | Britannica
energy, in physics, the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms. There are, moreover, heat and work—i.e., energy in the process of transfer from one body to another. After it has been transferred, energy is always designated according to its nature.

Nevertheless, Snowy 2.0 will store 350,000 megawatt-hours—nine times Fengning''s capacity—which means each kilowatt-hour it delivers will be far cheaper than batteries could provide, Blakers says. Yet his atlas shows that Australia has many sites more technically ideal than Snowy 2.0.

V = Ed = σd ϵ0 = Qd ϵ0A. Therefore Equation 8.2.1 gives the capacitance of a parallel-plate capacitor as. C = Q V = Q Qd / ϵ0A = ϵ0A d. Notice from this equation that capacitance is a function only of the geometry and what material fills the space between the plates (in this case, vacuum) of this capacitor.
