Energy density - Wikipedia

In physics, energy density is the amount of energy stored in a given system or region of space per unit volume.It may also be used for energy per unit mass, though a more accurate term for this is specific energy (or gravimetric energy density).. Often only the useful or extractable energy is measured, which is to say that inaccessible energy (such as rest mass energy) is ignored.

Microscopic energy density functionals have become a standard tool for nuclear structure calculations, providing an accurate global description of nuclear ground states and collective excitations. For spectroscopic applications, this framework has to be extended to account for collective correlations related to restoration of symmetries broken by the static mean field, and for fluctuations of ...

Today in Energy - U.S. Energy Information Administration (EIA)

Energy density and the cost, weight, and size of onboard energy storage are important characteristics of fuels for transportation. Fuels that require large, heavy, or expensive storage can reduce the space available to convey people and freight, weigh down a vehicle (making it operate less efficiently), or make it too costly to operate, even after taking account of cheaper fuels.

Energy density vs power density - Energy Education

Energy density is the amount of energy in a given mass (or volume) and power density is the amount of power in a given mass. The distinction between the two is similar to the difference between Energy and power. Batteries have a higher energy density than capacitors, but a capacitor has a higher power density than a battery.This difference comes from batteries being able to store more energy ...
