CRTs still use the same amount of light (not saving power)
And most lcd moniters use heat not light (still not saving power)
And I don't know what runs plasmas but if your that rich to own a plasma computer monitor you can probably afford to waste the power anyway

calm down buddy,

CRT's technically saves light when black is used, since crt's work by shooting electrons against a metal wall... the light generated by the collision iluminates the pixel. black = no collision at all

BUT, since the flyback (what generates the high voltage for that) is always running, you don't get to save energy...

No display runs on heat, plasmas run with the light generated by fire, hence plasma (plasma = fire)
lcd uses a backlight

theoretically one can save energy that way, but its too small for it to be noticeable
