As for a 25¢ cost- that could be too low. I know in my one car the block heater uses 400 watts; I would think in a big diesel engine it would be more. Even assuming the electricty rate is 8¢ per kw/h, that usually only counts towards about half of the power bill. So make it 16¢, and then assume the heater is on for 14 hours per night. (Plugged in at 5pm, unplugged at 7 am.) That's $2.24 on a work night. A Saturday or Sunday plugged in could use power 24 hours. Now you are at $3.84
Make the heater 1000 watts instead of 400, and you have new numbers.

For most commercial and almost all industrial installations, power is charged at a different rate depending on the time of day. Power in the middle of the night is about ten times less expensive than power from between the hours of 5-7pm. Superstore don't pay the same price for all the power they use each month, they pay a different rate each day and often for each hour.
Only a matter of time before this becomes commonplace in residential homes.
