And it's not just standby-mode "phantom consumption", as the EPA used to think. Today there are more devices with larger, sharper screens and hungrier batteries to charge, all left on for longer than ever before [2]. And it all adds up.

But electronics is not nearly as benign as you suggest, it depends on your lifestyle. E.g. I have 4 TiVo boxes running 24x7. Each draws about 40W. In my area 1W works out to about $1/yr. So my TiVo boxes cost me $160/yr just in electricity.
I also believe that LED lighting saves money. In our family room I used to have a 75W light bulb on for at least 12 hrs/day. That's $37/yr for just a single bulb. I replaced it with an 11W Philips LED. It's now costing me $5.50/yr. That's an over $30/yr savings on a single bulb. The same savings applies anywhere light bulbs are on for a long time.

There are probably a separate category of problematic electronics that really sucks power. I was offended to find my set-top box suck 18W. I am doubly offended by your array of Tivo boxes. For 40W, my laptop will be doing computation intensive task with the fan running loudly. My mac mini consume only 11W when idle. A big huge TV would use power. I only have a 32" TV and I use it only a few hours a day at most anyway.
