If we're comparing apples to apples all the time, sure. I think it's pretty obvious to most people who care to look that a 60w conventional bulb uses more energy than a 15w LED bulb (which, for the record, is the 100w conventional equivalent). Consider, however, these questions:

If my 2000w heater is running on the 800w setting and turns on when my room has dropped below the point I consider acceptably chilly and turns off above that point, how much electricity have I used in the last hour?

If I have 3 15w LEDs on a dimmer and run them intermittently throughout the day, how much electricity have I used in the last hour?

If my TV is off, but plugged in, and accesses the Internet a few times a day automatically to check for new versions, how much power has it used today?

I think this makes the case for, at least, a kill-a-watt style device. A whole home solution with sufficient report granularity and a report interface visible in the home would be worth the extra trouble, IMHO.

Edit: For the record, these are all real-scenarios from my house.

A while ago I bought one of those plug-in power monitors, and went around measuring everything I could find around the house. It's a worthwhile exercise, I think. You can leave an appliance plugged into it for as long as you like to get an average. I was able to make a pie chart of where my electricity is used in my house, which was enlightening, and led to some useful changes.

You can have per circuit monitoring, you need a CT for each hot conductor and a submeter with enough CT inputs for all of the circuits in your panelboard.

I’m happy with the Emporia Vue
