Hot water heater... turn off & on??? gas or electric???

I leave both on all the time. I imagine it uses the electric most of the time when plugged in. We turn the gas off when traveling. As many have mentioned you will have HW for most of the day even when not turned on.
Something to remember if you are using electric is, if the tank runs out of water and the electric is on it only takes a minitue for the electric element to burn out.
I don't see a need to turn it off as there is very little cycling throughout the day.
