Grid uptime. 2 articles, one more general, one mostly technical.

The US has more power outages than any other developed country. Here’s why.

An assessment of threats to the American power grid - Energy, Sustainability and Society

I hadn't heard of the 1921 Railroad storm before. It is estimated to be 10x the 1989 storm that took down Quebec, and destroyed that large xformer in New Jersey.

I do like EVs, for certain applications. I also know a bit about the magic that keeps the grid running. I'd suggest that anyone who is considering owning a non-hybrid EV as a sole vehicle read and understand the risks discussed in the second article.

Under widespread relatively short-term power outages, one of my priorities is being able to retain mobility for critical needs - medical transport, food, water, medications, evacuations..... I have a plan B with ICE - stock extra fuel. Even under totally normal conditions, I travel remote parts of Canada with 40L of extra fuel for ICE.

You can have a backup plan for EV transport, but after the grid is down is not the time to start thinking about it......

Complexity. I may sound like a Luddite at times, but it is precisely because I do understand what some of the failure points are, that I have concerns. In my case, this is not Fear of the UnKnown, but rather the knowns.....

There is a great paragraph in the second linked article, that relates to what I bang on about....

"The ability to operate a system in the absence of computer-driven actions is fast disappearing. The electric power industry spends over $1.4 billion dollars annually to replace electromechanical systems and devices that involve manual operation with new SCADA equipment [60]. With modest increases in efficiency come exponential increases in vulnerability. The extent to which reduced labor costs (and perhaps reduced energy costs) are passed on to the public is uncertain."

All we have to do is watch what happens in Western Europe to see the trends that will be soon in the United states.
I agree that Western EU bears watching.

There are enough differences though (Tax policy, and fuel cost being two obvious ones), that I don't think uptake in the US will be as rapid.

Densities and geography are part of what dictate different priorities (or, at least should), between here and across the pond....

If David Adair is for real fossil fuel is ancient history.

It has been nearly 50 years since I lived in Western Europe and from my observation over time we run more or less 20 years behind Western Europe.

With all the stupid "Smart" tech out there, it would be trivial to interlock the EV charger with a room-rental transaction.

with all the "smart" tech out there it would be trivial to defeat the room-rental requirement. :rolleyes:

In my version of the real world, people that can drive $100k EVs can afford to "fuel" it.

Is what it Is though...... if you're motivated enough, you can crack anything.....

I've seen a surveillance video of 2 guys wirelessly cracking a Tesla in the owner's driveway in the UK.... didn't take long at all......

What did crack me up though...... the only thing that seemed to slow them at all, was unplugging the charge cord, they almost had to drive off with it attached.....

How can a car MFG get carbon credits when to charge said Vehicle it almost always requires fossil fuels?
Because in spite of what the lazy media and lazy EV haters say, they are not carbon credits.

CARB states dock points for elements of conventional ICE vehicles which our superiors in the bureaucracy do not like. Subaru for example jumps through the stipulated hoops for their ICE vehicles to qualify as PZEV, Partial Zero Emission Vehicle, so as to minimize the Clean Vehicle Credits needed to sell in CARB states.

FFV Flex Fuel Vehicle also reduces the number of credits required to sell the vehicle.

CARB thinks battery swap EV is still a good idea and gives extra credits to manufacturers selling such in CARB states. Tesla took them up on this for several years. Then forced to actually field a swap station which produced even more credits but not enough to keep it in operation so they lost all battery swap credits from new vehicles after that.

As for the lame “fossil fuel electricity” argument, coal-fired electricity in a Model 3 is equivalent to 50 MPG gasoline. Plus unlike the gasoline vehicle an EV can effortlessly use any electric power source, vs requiring a very precise formulation of gasoline. For $10,000 you can buy a PV system and never again pay to fuel your EV. No moving parts. No byproducts. No scheduled maintenance.

Show me some math and a implementation plan for this please. You must know way more about PV systems than I do!

I would like to see exactly what type of system you ”think” you can put in for $10k (please include array, inverter, and storage if you expect to charge at night).

In the drive through?
Yes
It is a pain however because cables are only 20 ft long so every 40 ft you have to disconnect and connect to the next one up the line.
