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.

Dec 04, 2008· Human energy density is approximately 1000 J/m 3, while other inexhaustibles such as wind and tidal have energy densities of 0.5 to 50 J/m 3. This article provides an educational engineering mathematics framework for calculating energy densities of prevalent energy sources.

Comparing Nutrient & Energy Density in Foods

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 ...
