What is true is there are plenty of roofs, particularly in southern
california, that could be producing more than ample electricity. Look
at this sat photo, which if you zoom out, you'll see that it's one of
the greener parts of LA:
https://www.google.com/maps/place/Los+Angeles,+CA/@34.02302,-118.3071616,593m/data=!3m1!1e3!4m5!3m4!1s0x80c2c75ddc27da13:0xe22fdf6f254608f4!8m2!3d34.0522342!4d-118.2436849
I would guess that the land, including streets, is close to 50% covered
by roofs. I think, with current solar technology and some sort of
storage, that's more than ample for 100% of residential power with power
left over for tall buildings. No need for kilometers of solar farms.

Bill, you better check your math. It would take a lot more than "a few square
kilometers of solar panels put up to supply the entire world’s energy needs". In
very rough numbers, a square kilometer of fairly high conversion rate solar panels is
about 250 MegaWatts for roughly a quarter of the day (varies a lot depending on location,
and installation, and of course it's a curve, not a on for x hours followed by off for y
hours). That is not enough to power downtown Los Angeles - and I'm not talking about the
metro area, just downtown.
250 MW is one fairly small (by today's standards) power plant generating unit.

Yes, more or less. Over a seven-or-eight-year period, every gasoline and
diesel vehicle in the world could be replaced with electric at no cost, the
entire petrochemical fuel infrastructure could be dismantled, and a few square
kilometers of solar panels put up to supply the entire world’s energy needs,
after which energy would no longer be a cost, and we could reclaim the many
trillions of dollars that are being spent on petrochemical subsidies each year
for actual productive uses.
There are people who argue otherwise, but they’re fundamentally innumerate.
And that’s really unfortunate.

Last time I ran the numbers, every fuel vehicle in the world is being
subsidized by more than USD 5000/year in governmental subsidies to the gasoline
and diesel industries.
There’s a huge amount that you could do with that money.

Lawrence is right, Based on my research, just the Electrical energy used
ALONE for all the processes that culminate with a gallon of gasoline in
your tank can move an average EV at least 50 miles. Another surprising
fact: CA's largest industrial user of electricity is petroleum.

I would think that simply not using a liquid powered vehicle would have
these benefits and energy gains. Energy loss to: Survey, drill, pump,
transport, refine(this is a big one) distribute, pump again and then you
get the energy to use plus the added benefit of poisoning every one
breathing the atmosphere. The elimination of fossil fuels would free up all
that energy to use in the electrical grid. So have no fear of running out
of energy. There will be a reduction of energy use with every new electric
vehicle. Don't get me started with product packaging and the use of
plastics. Lawrence Rhodes
