The Kindle is specifically this model:
Kindle PaperWhite 2 (2013) WiFi (4GB) (U.S., Intl.)

Well there you go, thinking again.
The screen does not use any energy on or off, only when changing the display.
Like real ink, it is meta-stable. It retains the last thing written to it.
IF the device is an ad supported Kindle -
IF you failed to put it in 'airplane mode' -
Then it will wake up at regular intervals to check for new ads.
Wifi, in general, does not use as much power as 3G but it is a factor.
When done with device (for the moment) -
Enable 'Airplane Mode' -
Hold power button until you get the pop-up panel -
Select: "turn off screen" (which means its lighting - the screen is 'always off' except while the display changes).
