I look after it not because it is extra cost per kilowatt hour, my rate 
(almost free) stays the same throughout the day. It is the stiff penalty 
for every kilowatt over the limit I run, even if I only hit it once per 
month. I am constantly on the edge of hitting the penalty just by 
living, so I look after every watt that is consumed by around-the-clock 
devices and have things on timers all over the house. I looked at X10 
devices to further manage household power usage during they day, but 
they are still so expensive that I stopped calculating the payback 
period after I hit a decade.
