I live in NW Vermont, I heat with wood, backed up by a 35K BTU
propane heater. I use propane in an on demand tankless HW heater, and
a propane powered 17 cu ft refrigerator/freezer (0.25 gallons per day
avg). We have all the usual amenities, satellite based TV, satellite
based Internet with multi-drop network for 3 computers, microwave
oven, clothes washer. All our lights are LED or compact fluorescent.
All of our appliances selected for energy efficiency (which means we
paid an overall average of 15% more). All appliances that present
phantom loads have cutoff switches wired to their receptacles or are
plugged in via a power strip with a cutoff switch. We don't have a
clothes dryer, we use indoor racks in winter and clotheslines
otherwise. We have two water pumps, one a 120 vac 3/4 hp shallow well
pump draws from the well and pumps 14 meters up across 180 meters
run to a cistern and a 120 vac 1/2 hp which draws level from the
cistern and pressurizes the house system.
I run two inverter systems, the first is a high efficiency 1000 watt
since wave unit that runs 24/7 powering the satellite TV receiver,
the internet network (satellite modem, Apple wireless station/router
and server, cordless phones and answering machine. The bulk of of the
house is powered from an Outback 3.5 KW since wave inverter run on
autostart. Its all powered by PV arrays totalling 1.6 KW feeding two
battery banks of 22 KWH and 12KWH capacities. I do have a 6.5KW
gasoline powered generator that gets run an average of 6 hours per
week in our 'grayest' months, November and December under an average
load of 2-3 KW to pump water for the cistern and simultaneously get a
little 'topping off' of the battery banks. From mid-February to mid-
October we often go weeks without ever firing up the generator.
On my worst most extravagant day running everything, filling the
cistern, cooking a big dinner in the oven (gas oven but 300 watt
glow bar), and my wife going on one of her manic marathon vacuuming
sessions (we have three dogs) I use 7-8KWH, typical is 3-4 KWH. I have
never really sat down and figured the KWH of the propane consumed,
but over the last 15 years the annual consumption has been 250-650
gallons (the variation mostly dictated by Spring and Fall temperatures
when its just too warm to run a woodstove round the clock, but not
warm enough for no heat source, so we run the propane.)
When I look back over the daily figures being quoted here in this
thread I am reminded of Walt Kelly's famous line from "Pogo" ... "we
have met the enemy, and he is us!" These people who are only
interested in their bottom line profits who build these kinds of
housing should be forced to live in them and pay the bills
