For my area perhaps. Cold winters that reduce mile/kwh by -20%, but not that bad, but the traction control on electrics is awful. You get stuck pulling into your driveway if there is a little bit of snow slime there. So not optimal for any snow slick conditions. So perhaps REALLY not optimal for your clime. A 3 season car in Alaska probably.

Not a very good choice here for sure, and the penetration so far as I have observed is not very good.  Cold weather battery performance also depends on how cold for how long it actually gets.  Typical winter temps in the lower 48 of 20-30F might give you -20%, but a month solid of sub-zero is another can of tuna entirely.  Heating the cabin while using the vehicle takes a shit load of the juice as well.  We also set a new snowfall record this year, so performance on slippery roads is a big factor.

"3 season" also gives false impression that it would be good 3/4 of the year, but winter conditions exist here in fall and spring as well.  Nov-Mar can all be ugly, so it's almost 1/2 the year it's not a great choice of vehicles.

I doubt they will ever make much sense up here, unless you can afford both types.

It sounds as though you have just provided the causal mechanism for all the peak oil claims of the early 21st century. Bravo Sir!

My panels, the most recent are at least 12 or more years old, likely in the 15% efficiency range. I got to look over some of these new bi facial panels that appear to be the new hot thing. The first thing I noticed was the size, something like twice or more bigger, maybe 2.5 times the size but to my surprise not heavier than my old ones, very thin aluminum frame and the glass must be thinner. They claim something like 20% efficiency from these. I am impressed, greater wattage for materials used. I just adjusted the settings on my Mppt controllers taking roughly 3000 watts off line until next oct. don't need the power from them, I just use my panels with the pwm controllers now, wind turbine now has the phase wires shorted until next winter. No point letting it wear the bearings when I don't need any power from it.

I can agree with you.  But claims go both ways.  So which is easier to find?  Someone who says the world is getting warmer because that is what the world wants to do, with nothing to do with humans.  And that wee have oil enough for 500 years.  Or someone who says this shit is going to be so hard to get in twenty years that our society must collapse and people will starve.

Which is the more popular delusion?  If you are having trouble.  I suggest door number one.

M. King Hubbert however is in a class by himself.  He was the leading American geologist.  He also was not wrong.  What blew most peak oil claims up is that the proponents were too attached to a single peak.  They were enamored with the simplicity and did not look deeper.  The truth is that the amount which can be extracted has increased with advancement of technology and the state of the art.  This moves the peak but does not turn the idea of peak oil into bullshit.  Reality actually suggests the ride down the peak will resemble a Seneca cliff.  When the state of the art is lost it does not come back.

A doomer with a scientific bent, and that fully describes me, realizes that things are working out exactly as we thought they would twenty-five years ago.  The timeline is working out different, and that is all.  That does not mean much to me.  Just because people can't predict exactly when something is going to happen does not mean it will not happen.  Collapse happens like the Iceland volcanoes erupt.  You will drive yourself crazy following 'predictions' of eruptions which are sure to happen.  Check every day, and after a few weeks of no eruption you will think the volcano will not erupt.  You have sour grapes.  Then the volcano erupts  Like it did twice last year. 

So it is with collapse.
