Do you think that e.g 100 shots at 1/10 sec. exposure equals to 10 shots at 1 sec. regarding energy consumption? Assuming other factors are the same.

good question

IMO: no, the camera will use more energy processing/writing 100 shots

bernabeu is right on this. Camera will use more power while it's doing something than idling, but the less you let it idle (idle meaning ready to take picture with everything on and not in power save standby) the more pictures you will get per picture.

Unlike film cameras, digital cameras use a significant amount of power relative to when you're actually taking pictures.

My P&S Panasonic draws about 0.25A @ 2.4v with the LCD on and ready to take a picture while flash charging approaches 1A and processing and zooming takes around 0.5A.

Flash and idling are the battery life killers.

For a point and shoot I imagine the SENSOR would use about the same amount of power, but then those 100 pics all have to be processed and saved which would used vastly more energy than for 10 pics.
With a dslr it's even worse - 10 shutter actuations vs 100 and the sensor doesn't draw power continuously so 10 times as much sensor power too.
