True Cost of Energy Comparisons – Apples to Apples
For example, At 85 percent efficiency and $1.80 per gallon for propane and $0.70 per Therm for natural gas, the costs per MMBtu are $8.24 for natural gas and $23.12 for propane. These prices can vary, but the lower cost energy in this particular example (all other things being equal) is natural gas.
The energy density of AA batteries varies depending on the type of battery. Alkaline AA batteries, which are the most common type of AA battery, have an energy density of around 100-150 Wh/kg. Lithium AA batteries, on the other hand, have a much higher energy density, with some models reaching up to 300 Wh/kg.

In physics, energy density is the amount of energy stored in a given system or region of space per unit volume. It is sometimes confused with energy per unit mass which is properly called 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. In cosmological and other general relativistic contexts, howe…
