I wouldnt be worried, especially if you have a large entertainment center (stereo, tv, gaming, movie player) or multiple setups and computers in the house, you (and any family) can just claim you are always watching movies or TVs in various rooms as you move throughout the house.
if its just you, with only one TV, a simple comp, and your fridge...you might wanna cut back a lil if possible....neighbors always recognize habits like "how many people", "what time lights come on/go off", etc, and even that little info combined with a high bill would give cops a reason to do a "sniff-by"
