Does a steady or a blinking digital clock use more energy?

I think the question you're really asking is "does the energy savings from having the LED off part of the time outweigh the energy used by the circuit doing the blinking?" It's hard to answer this in the general case because there are so many variables. If we assume the clock circuitry is simple and well designed, which is probably a reasonable assumption, it's likely the blink circuitry is lower power than the LEDs so it should save power.
