Actually, our power is about $0.035 per KWH up to 300 KWH and $0.043 above
that, so your figures are about two times too high. (Out of curiousity, is
there anyone with cheaper power?) Also, 78 RPM is a slight exaggeration. It
seems like it's going that fast, but I don't think it really is. Also, the
average rate is probably a lot lower than this. For some reason, I seem to
look at the meter when the dryer, water heater (no flames--I rent), oven, and
air conditioner are running. :-) The water heater, dryer, and air conditioner
use 4.5, 5.2, and 1.6 KW, respectively. I don't know what the oven uses.
