For the most part, esp. in Nor Cal, the power company doesn't care if you use more, just so long as you pay, they keep happy/quiet. Now if your usage jumps 50% or more, they might ask you questions. Maybe get an old hot tub and put it in the back yard. Those use lots of power, and although you wouldn't even have to fill it, it's a good cover. You also get the added benefit of about 500 some odd gallons of water storage that would be great for indoor.

Also, under no circumstances should you hack into the power box and steal power. That's an excellent way to get caught, so don't do it.
