If you do not use specific reader feature (backlight with white led diodes with some warm red for
eye protection), there is just reflected light from various sources (sun, lamp) ...So, no aditional energy usage for that purpose.
Once these micro-capsules from which eink display is composed flip their polarity (pigmented particules), no electicity is used to pertain this state of display.
Cheers!
