I can think of a few things that burn more energy per second that I'll burn in my entire lifetime via the use of encryption.

Coincidentally, they're all, somehow, insanely useless.

According to my Macbook Pro's energy sensors the predominant user of energy is the screen backlight, most of the time.

Crypto functions are so optimized in hardware that their energy consumption is insignificant...
