It's really supportive to hear Tim's and Larry's testimony. So often I
hear or read that solar is too problematic because we need massive solar
farms, which will be expensive and have significant ecological impact.
(My speculation: this comes from energy company propaganda, indicating
they don't want to take losses on their current infrastructure or loose
a source of revenue.)
Here is direct evidence that, at least for residential, that isn't the
case. Progress in solar roof tile technology will make it relatively
cheap and very practical to have solar roofs pretty much everywhere -
and perhaps cover 100% of residential electricity needs, on average. I
can imagine future technology where windows, particularly on office
towers, would have a solar film, perhaps with electronically controlled
polarized glass, that would be nearly transparent when in shade and
active when in the sun.
Thanks for posting !

I was very happy when you spoke up at SEVA. Although I thought my
calculations were reasonable, I did not have them peer reviewed, and so I
was not sure if I had missed some important aspect, but your actual results
confirmed my views. So, thanks a lot.

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!
