- I wonder whether Southen California Edison's ability to reduce its forecast of
- peak demand by 500MW (out of more than 15000MW; that's 3.3% of peak demand)
- might have had anything to do with their campaign in the early 80s to get
- customers to reschedule activities that used electricity to off-peak hours.
- Things like not running your washer and dryer (most home dryers are electrical)
- between 10am and 9pm. Seems like that could put quite a dent in peak demand.
- Doesn't do a damned thing about total demand, though. Coal and nuclear plants
- are BASE-LOAD plants; they run 24 hours a day.

- And, largely due to what they consider overregulation by the state, businesses
- are currently fleeing California in droves.

- No, we're talking about confusing total demand with peak demand. See John
- McCarthy's sig, and add to it "And those who don't pay attention to what the
- numbers they're using for their arithmetic mean are no better off."
