Definitely.
I have a household with 8 people in it and last year we generated an
average of 3.077 kWh a day. Take off 15-20% for losses and it's
about a sixth of what you are talking about.
It just isn't practical to run a conventional hogging American house
on RE. You have to get your load side _very_ efficient before you
even think about it. Unless money isn't an object...
We have a big refridge, but I bet it's 6-10 times more efficient
than the one you are using. Ovens have to be gas on RE, unless you
have lots of surplus energy to shoot. We have a clothes washer, and
at present we have several dishwashers - the human type. :) But I am
looking into buying a dishwasher. I can't just go to the appliance
store, though. I have to shop for the _most efficient_ machine out
there. That's the nature of living on RE, unless you have lots of
dough.
Yep. If you are on the subsidized grid, RE cannot compete dollar for
dollar. There are other advantages to going with RE though, of
course. Lots of people do it for non-monetary reasons.
And as a famous solar instructor (Johnny Weiss of SEI) says, we
don't ask what the payback on a Mazarati is, do we? :)
Only because most taxpayers are utility users...
Yep. I hear you. But I'm in the camp that says that we shouldn't
wait for someone else to make it easy for us. I think we need lots
of folks doing it because it's the right thing to do, not just
because of dollars. Then the dollars will become less of a hurdle,
as more people use it and the prices go down.
But I understand the situation you're in. It's hard to put money out
when the grid is cheaper. If I were in your situation, I'd probably
make the same decision, hard though it would be.
