my peco bill says 237 kwh at a cost of 13.05 cents per kwh + $5.10 for
"basic service," + 114 kwh at a cost of 5.48 c/kwh + $4.58 for off-peak
"basic service," (an electric water heater) ie a total of 351 kwh for
$46.86, or 13.35 c/kwh, or about $560/year.

me too... what's next? an off-peak battery charger and inverter? if
charging and inverting were 20% efficient, this would increase my
non-off-peak consumption to 237x1.2 = 284 kwh/month, and lower my bill
to about (284+114)x$0.0548+ $4.58 = $26.41. will peco provide off-peak
service without regular service? the inverter has to simultaneously
run the well pump and stove and fridge...

my old computers use less power... but it looks like i have to pay $9.68
per month in service charges even with no electrical energy consumption.
electric utilities typically put 2 kwh of "waste heat" up the cooling
towers for every kwh of power they generate. maybe it's time to unhook
from the grid. put a $900 1800 watt 92 pound honda generator in the
basement that makes a total of 8.8 kw of heat while burning 0.23 gallons
of gasoline per hour at the 1500 w rated output, ie 16.9 cents/kwh. if
that heat made hot water, i'd only need 284 kwh/month, running the generator
for about 6 hours per day, at a cost of $48.06 per month, if gas costs
$1.10 per gallon. maybe this off-road gas would be cheaper...

it's 60 f in my house too. i turned off the furnace and built a sunspace.
