11. Does this difference in composition lead to a non-negligible difference in specific energy ? 12. Ragone chart showing specific power vs . specific energy of various capacitors and batteries 13. The theoretical specific energy densities for metal-air batteries are higher than for ion-based methods. 14. Supercapacitors vary sufficiently that they are rarely interchangeable, especially those with higher specific energy . 15. Energy density and specific energy are the engineering terms that define these desired qualities. 16. In some situations, selection of only a specific energy of neutrons may be desired. 17. Specific energy consumption is 6.8 kWh / m 3.18. In a divisional organization, there should be a central and several sector-specific energy management units. 19. In quantum mechanics, the canonical ensemble affords a simple description since microstates with specific energies . 20. Specific energy consumption is used as the main indicator to quantify the required building quality.
