What's watt, what?

In the interests of saving even more money (as if snatching cheap butter from the world's population of poor people weren't enough), I have decided to shift my energy consumption to the off-hours. I read recently that electric companies charge less for energy used in off-peak hours, so as of this week I am trying to run all major appliances (excluding things like fridge, A/C, etc.) after 8:00 (p.m.). It's proving to be a good discipline for me, as it forces me to plan my days better and schedule my time such that I'll be loading up the dishwasher or dryer at the stroke of 8:00. We shall see if it makes a noticeable dent in the electric bill next month.
