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

I'll turn both gas and elec on when I wake up in the morning. I'll shower after my cup of coffee and DW about an hour behind me. Once she is finished showering I'll turn off the elec but leave the gas on until I hear the gas burner cycle off. Then I'll turn the gas side off and repeat this routine the next morning. The water is still warm enough for evening dishes.
