Ten years ago, there were still a lot of big CRT and plasma TVs. These were real energy hogs if you watched a lot of TV. There were also more desktop computers (not many people have those at home now, except for gamers) and they could pull 400W. One I had was quite useful as a space heater when the boiler packed up; I set it to work cracking Windows XP product keys all evening to keep the CPU at 100%.
I suspect incandescent lamps were also a lot more prevalent. I kept them for a few things because CFLs were so shite. Now there are decent LEDs, it's much better.
The biggest user of energy in most homes is, however, the fridge/freezer.
