If I wanted to use Blowfish or Twofish to provide security on a device where power consumption is crucial. Regarding power consumption, which one would win?

Generally, which algorithms are known to consume the least energy and why? Which parameters should be considered the most? How much research is done regarding power consumption of cryptographic algorithms?

Cryptographic primitive performance is highly dependent on the implemented platform, Keccak for example, will obliterate Blake in hardware design, but the exact opposite is the case on an x64 CPU –  Richie Frame May 29 at 18:49
