Those are perfect examples. How much does your TV cost to run? How much more (or less) are you spending with a "smart" fridge over a "dumb" one? What is the value of that vampire current when everything is "off"? Literally, tell me. Dollars and cents. How much is it for you? How much less will you spend if you set the AC to 76 instead of 74? How much does a shower cost per minute? How much do you save taking a "hot" shower instead of a "scalding hot" shower?
