An e-ink screen cannot burn in, so the infrequent screen change is not a problem (the change does need power!).

Also, when I'm not going to read in, let's say, 4 hours or more I just turn off the device, sleeping mode consumes a little energy but not because the e-ink screen but the process running on background, I think it's like 0,5% of the battery per hour.
