Orders of magnitude (specific energy density)
From Wikipedia, the free encyclopedia

It has been suggested that this article or section be merged into energy density. (Discuss) Proposed since August 2011. |
This is a table of specific energy densities by magnitude. Unless otherwise noted, these values assume standard ambient temperature and pressure.
| Order of magnitude J/(kg) |
Specific energy density | Storage method |
|---|---|---|
| 101 | 1 | gravitational potential energy stored by raising any material by 1 meter (near the Earth's surface) |
| 102 | 2.8 | day laborer (for that day) |
| 4 | heel-strike generator using electrostrictive polymers | |
| 103 | ||
| 104 | ||
| 105 | 2.16 | NiMH rechargeable batteries |
| 6.12 | lead acid car batteries | |
| 6.3M | Li-ion watch batteries | |
| 107 | 1.6 | wood fuel |
| 1.7 | protein (about 4 nutritional calories per gram)[1] | |
| carbohydrates (about 4 nutritional calories per gram)[2] | ||
| 2.5 | ethanol | |
| 2.9 | alcohol (about 7 nutritional calories per gram) | |
| 3.8 | fat (about 9 nutritional calories per gram)[3] | |
| 4.4 | petrol (gasoline)[4] | |
