I find it incredible what amount of energy gets wasted that way.
The energy waste is in the CPU/GPU still working on the graphics even after the screen has powered off. My guess would be very uneducated, but I don't think that's very substantial.
I fear it indeed is:

164 W idle vs. 207 W with load ( 43 W difference)
297 W idle vs. 472 W with load (175 W difference - yikes!)
versus the ~30 W your average 19" TFT consumes.
Agreed, with a screen saver you probably won't get your CPU or GPU to max
energy consumption, but you can see that there is a significant difference
between idle and load. And it's at least in the same league as your TFT's
engergy consumption.
