Range clock - Disconnect it!

I doubt the LED clock on my stove uses as much energy
in 1 year as one burner uses to boil a pot of water in 5 minutes.
how much water? call it about a gallon. This is an very large amount
of water, since when most of us want to boil water in 5 minutes we're
talking about coffee/tea water. But hey, it's an easy number.
It takes about 1200 BTU to boil a gallon of water
BTU suck, so the conversion to watts is
1 BTU = 0.3 watt-hours
ergo 1200BTU *.3watt-hrs/btu = 360 watt-hours.
now...let's do the math...
365days x 24 hrs/day 8760 = hours/year
If your LED clock uses 1 watt/hour then it consumes 8760
watt-hours/year. If your stove clock is LED, 1 watt is __very__
conservative and generous to your case.
8760 360
THEREFO
It takes at least 24 times as much energy to run your 1 watt LED clock
as to boil a gallon of water.
surprised? Time is a funny thing...
