Hey Larry, I think that was me. I did car/house/solar+storage and we are
about 95% net zero on an annualized basis. I am installing a little more
solar and converting my diesel tractor to get to 100%. The upfront cost
is there but now the savings are big. Low fuel and maintenance costs for
the EV's. Same for a passive house, with the bonus being excellent air
quality inside, and cozy warm in the winter. And solar, even here in the
great Pacific Northwest is like magic, super low cost to maintain,
basically clean them off once per year. It's the perfect retirement plan
for me, low outgo, maximum payback and supreme fun!

Some time ago I made a presentation at the Seattle Electric Vehicle
Association (SEVA) in which I showed that, even in the Seattle area which
has the worst solar energy in the USA (other than Alaska), by combining 3
existing technologies: (1) electric cars, like the Model 3, (2) the
European Passive House Design, and (3) a 10 kW solar panel, that the
combination of house+cars not only is net positive in terms of energy, but
reduces the total amount of energy use by a factor of 9-10, even when you
include the energy needed to manufacture and install the 10 kW solar panel.
At the end of this presentation, one of the SEVA members got up and said
that he had actually done what I merely calculate and talk about, and that
my figures are very close to what he has observed in reality.
