Analysis that came out today about Russia's vehicle fleet. Bottom line: 25-50% of the vehicles remaining in storage have been stripped for parts to restore the others. Could those chop-shopped vehicles also be restored? Yes, but it'll take much longer and be more expensive.

Those graphs are incredible.  We need to stop burning stuff as soon as possible.

For me it's the sheer volume on a global scale:  100 million barrels (= 4.2 billion gallons).  Every day.  Almost 50,000 gallons every second.

slightly different way of looking at the same thing...

Breakdown of products from a barrel of oil, per the EIA:

For most body damage, there's usually a cheap version of a fix: a mismatched panel from the junkyard, plungering out the dents yourself instead of getting them professionally fixed, using a touch-up pen to cover up a scratch enough so that it doesn't rust instead of heading to the paint shop, etcetera.   If you're willing to live with those sorts of fixes, I'd suggest collision isn't going to be worth it because the much higher costs of professional body work are built into that premium.

However, if not having everything just right is going to bug you, then insuring to cover all the pro body work isn't a bad idea.

I used 6% but readjusted my numbers annually based on the College Board report on college costs that comes out every October/November.  The last five or ten years, 6% turned out to be too high for the costs I was including (TRBB&F at a public 4 year school) because my projections / planning just got rosier and rosier without me doing much.

Who knows what the future holds though.

Very true on not knowing what the future holds. I'd like to be overly prepared as the one thing that set my husband and I back for awhile was the student loan debt we graduated with. I see coworkers who had everything paid for them and wish I got to have that $0 start too. Competition and cost consciousness might make the 8% inflation expectation I had not nearly as bad, but 18 years makes a lot of time for inflation to pump up the number a lot.

 Indeed, 18 years is also a lot time for the higher education system to collapse under its own weight. If typical college becomes say, $300,000+ per kid in today's dollars, it stops being feasible for most families to send their kids too and it forces change. I hear you on student loan debt, but having  >$750,000 locked up in a 529 is astounding to me. The "risk" becomes they get scholarships or don't take a usual approach, or the fundamental nature of higher ed changes and that money is now not accessible.

Hypocrisy check: I have three kids with $0 in 529. Now that I live in a state with a tax break, I'd like to contribute a small amount to 529s, but I'm cash flowing grad school and a home renovation now. I'm mostly going the Root of Good route with advance credits, community college, and scholarships. Still have 7 years to plan.

I will be retiring at the end of this school year and I will be moving back to my hometown to be close family.  It costs me about $4000 a year for the house here between utilities, taxes, insurance, etc.  I have set up four scholorships for $1000 each for students that attended the school I have been teaching at.  It's not a lot but I hope that it will give some students a small boost.

I was at Walmart yesterday and noticed the electric push lawn mowers there are now cheaper than even the cheapest gas lawn mower somehow. ... And assuming the battery lasts the lifespan of the mower they are cheaper to run also.

The battery of a mower won't last the life of the mower.

There's no comparison between the batteries in a car, which are massively over sized and spend most of the time at very low discharge rates, and mowers which have undersized batteries which are discharged at full output until they are empty. The life expectancy of a mower battery is short.

Replacement batteries are also pretty pricey at the moment. Hopefully they'll get cheaper in the future.

True - but I use my mower 14 times a year usually, give or take a couple mows.

I use my car probably 400 times a year.

There is significant difference in usage.

It's not the number of uses that's important but the depth of charge/discharge.

I use my mower about 40 times a year for about 2 hours a time. There are 4 batteries (total 14Ah) which will all be discharged for one cut. I have 2 batteries which have already died.

Can't say that I've noticed any loss through keeping them fully charged, but then I wouldn't.

Of course if you don't use the mower very often and not for long the batteries will last indefinitely.

Right....

Completely, well sort of unrelated...

According to wikipedia lithium iron phosphate batteries have an expected life cycle of over 3,000 in most conditions.

 https://en.wikipedia.org/wiki/Lithium_iron_phosphate_battery

There are some mowers that are advertised with lithium iron phosphate batteries. See here for example.

https://www.yardforceusa.com/yf56vrx-rer38-li50-riding-mower

On their website they list an expected life cycle of 1,000-10,000 charge cycles.

I wonder how long a lithium iron phosphate battery would last in real world conditions.

If you don't mind me asking, how many years did your first 2 batteries last before they stopped working?

So -If the world stops using crude oil as much for transportation, how will the big oil companies react?  Will they find new uses for crude oil other than making products that burn?  Could the crude be used to make building materials, for example.  PVC  lumber is kind of good as it is waterproof.

Until everything in our world stops being made of plastic, I wouldn't be worried about oil disappearing any time soon.

The current rate of global extraction and processing is truly astounding - over 100 million barrels each day.
About 3/4 of that goes towards making gasoline and diesel.  Another 5% or so is kerosine. Most of what's left is asphalt and a variety of lubricants of different viscosities.

The precursors to plastics make up just 2-3% of each barrel of crude.  Ironically a primary reason why plastics are so cheap is that these petrochemical feedstocks are just what's "leftover" from fractioning off the ~3 billion gallons of gasoline and diesel we burn through each and every day.  Plastic is so cheap because we use so much petroleum fuel. In a hypothetical world where no one burned gasoline or diesel the cost of plastic might be 100x what it is today.
