Yup!

The talking bobble heads on CNBS definitely thought it was ridiculous.

“Crazy”, “magically”, “irrational” are just a few of the words used among laughs, smirks and other gestures.

This video cracks me up. Watching this (first time for me) makes me wonder why any lawyer in their right mind would take up the lawsuit about Musk‘s compensation plan.
 
I think US legacy automakers have a different reason altogether to create new factories. By moving to a different state, I think GM and Ford can open a new facility and escape many of the union obligations their existing factories have.



AFAIK back in the mid-late 70s GM tried a strategy of building plants in non-union parts of the US (south and southwest) but in the end national contracts with UAW killed it and GM ended up allowing unionization at those plants too. Story about it from 1978-


Then GM tried just a couple years ago to avoid the national contract issues with requiring acceptance of unions by opening "joint venture" plants with battery companies that weren't necessarily covered by the national contracts...and again pressure from UAW got GM to back down. Story about that from 2021
 
Even Apple had to declare dividends when they were generating huge amounts of profits and no clear way to reinvest in a productive manner. I don’t think Elon and team are at that point but whenever that happens, it’s appropriate for any company to return capital to shareholders (buybacks are equivalent to dividends, just a different form).
I think the big difference between buybacks and dividends is it’s easier to structure buybacks so they are done opportunistically to boost shareholder value when it makes sense for the company and the investors. Companies can quietly buy back shares when the SP is soft and hold cash when it is high.

Investors like dividends with predictable payouts, buybacks they are just happy to see when the company gets a good buyback price.

The other massive difference is buybacks are not subject to double taxation. I think this last reason alone is the big reason dividends are becoming a smaller percentage of investor payouts for a lot of companies.
 
From the "Tesla Model X Owners Club" on facebook:

"The Tesla service center near my house had about 20 Model X all lined up nice and pretty in the parking lot. My curious self had to stop in and find out why they all had QR codes on the windshields. Can you believe they are all $20,000 cheaper than MSRP!! I asked one of the service guys who obviously had no clue because he didn’t even realize there were QR codes on them. But his boss came out and told me that all the showrooms are clearing out their older X and S. And that all the showrooms will be receiving a new product on Tuesday. ... Not to mention, these cars for sale are 40K cheaper than when I bought my X."

Presumably FSD HW 4 will start shipping Tuesday. Sigh, and I've only owned my Model X for 14 months now...

Given that the last three hardware versions (and who know how many major software revisions) were supposed to enable Full Self Driving what’s the chance that this is the one?
 
I haven't been able to identify a resource constraint on the cell supply side that acts for any significant / identifiable duration. I'm not saying that one won't become available, and I'm not saying that I've done some massive investigation, but I've been asking around for a while and nobody has murmured a peep. I've spent a while in my life pulling stuff out the ground so I know there is a cost to it and plenty other issues. Exploration cycles and stuff like that. But the evidence to date is the cell supply industry is solving the challenges so as to scale in a cost-effective manner in conjunction with their their client base. So for now my model runs without a cell supply growth constraint.

Given that I don't particularly mind if the cells are first life or second life. However by 2040 the second life & related reuse/recycle efforts should be beginning to get serious volume. So if anything that eases things much as in the steel or aluminium or copper industries, i.e. load once, then reuse and just add raw material for growth and wastage. If I could identify a constraint I'd sweat this aspect a lot harder. If anyone knows a constraint please speak up. In fact that is the main reason I have put a scale marker down on the table so as to get the hive mind to focus.

It just so happens that the natural outcome was complete transfer by ~2040. I didn't set it up to achieve that, it was just how the model solved, even after allowing for transfer constraints that I built in. That included allowing for per capita energy growth, and for population growth, and of course the consequences of transferring from fossil to renewable (i.e. for anyone who models this stuff I've allowed for the difference between substituted and direct, and consequent shrinkage in substituted). But given that a full transfer occurs then that becomes the new 'steady state'. However it doesn't account for any 'extra' additional demand arising from dreams of infinite free energy - they may exist but I am a cautious person. The implicatio is that this is ramp over, stable state achieved. But I will say that it is with less of an intermittency buffer than I would like - I used to have the toolset to model intermittency buffers very well, but right now I am having to drive on a reservoir of knowledge in that area, nevertheless it does look light to me and so further intermittency reinforcement might be helpful. Against that, I should also point out that I haven't explicitly quantified any potential high capacity long distance (1000-km x 100+GW) grid links that can make a non-trivial impact on storage requirements.



Perhaps I am phrasing things poorly, please excuse me. This calculation does not assume that the batteries will be the growth limiter, quite the reverse. Instead it sets out the minimum supply required for them not to become the growth limiter. In fact the model drivers are:

- on the vehicle side : the history-matched S-curve that works equally well for all three of (#EV; EV-GWh; %EV);
- on the global energy side : the observed historical growth rates (and observable changes to growth rates) in all the non-fossil categories (and the rate changes in fossils) + population changes + energy/capita + various constraints except for in cell supply + drivers for intermittency coverage + the given levelised cost environment we have.
- and the result assumes that cell supply is not the limit provided that this cell quantity is achieved (as the intermittency coverage is set at a scanty level, i.e. probably better be higher as a first order estimate).
- the assumption that external (endogenous) perverse incentives do not materially interfere (e.g. ROPEC+ declaring war on humanity, etc).

It is actually a very simplistic model as these things go, but sufficient for my purposes at this time.

Personally I thought the result was quite positive, i.e. full vehicle transfer by 2030, and full energy transfer by 2040. I've not seen any other serious modelled scenario that comes out with anywhere near as optimistic an outcome as that. (I think) this is because I am identifying the real current situation from a position of clarity, and I am able to cut a minimal-necessary model in a very short time in a particular manner. I expect that in three years time all the mainstream modellers will start to cautiously put forwards what I am seeing as their 'best' scenario, but they have such long revision cycles and publication cycles they are always driving in the rearview mirror 5-years after the event. So anyway how fast do you think this transition can be done ?
Can you or someone give some idea on where we are on the recycling costs to extract minerals ? I understand at this time the costs are higher than mining, extracting and refining from ore, but not sure how much higher.

And also what is the cost trajectory look like and when is the cost expected to get on par with mining?

The woman was extremely annoying. Market cap targets are actually not that weird. Stock options implicitly use market cap targets since you get more compensation (or zero) as the stock price moves.

But yeah, funny how these “expert” talking heads thought they were so smart…
 
Very interesting, but one thing I am not sure I understand correctly: You talk about a demand curve, but there is no curve labelled demand in your plot. Do I get it right that the blue curve is production up to the present and projected demand in the future? And the other curves are the future production for different end dates of exploiting new oil reserves, so only the existing ones at that point keep producing, losing 6.5% of their output per year?
Let me try to answer your question - there are a few things here.

1. Pretty much there is very little storage for oil. So figuratively speaking what we produce today, we ship tomorrow, refine the next day, and use the day after. At any given time the world can only support about a 1% or so difference between supply and consumption for a relatively short duration. After a month or so of more than 1% or so mismatch - in the oversupply case the tanks are literally brimming over, or in the undersupply case the oil price hits $120/bbl or more to encourage additional supply to be produced. So for all intents and purposes the historical supply (production) line is also the historical demand line at the price in the market at the corresponding times. If you look on that graph, at the historical blue line you can see the demand reduction from the 2008 economic downturn and from the 2020 Covid pandemic. There is a limited amount of extra supply that is kept on standby (primarily by Saudi Arabia and the other OPEC countries) so that if demand goes up unexpectedly, or a major incident happens somewhere (like a big war in Iraq & Kuwait, or something) that everything stays flowing smoothly.

2. Looking to the future I have also plotted a future blue line. That is the production required to meet oil's share of future energy needs as dictated by the model I built. As renewables get built out in ever greater quantities there is less oil used in heating houses or running cars, or whatever. I have similar (but slightly different) future production curves for gas and for coal. Ultimately the model shows that the fossil fuels simply aren't desirable by 2040. No-one would demand to buy them so no-one would produce and supply them. I'm being slightly simplistic as very minor amounts of greases and lubricants and chemical feedstock are still of interest, but they are not significant quantities compared with the overwhelming amount of oil that is used in one way or another for energy.

3. I'm not doing anything magic in my modelling, or relying on any magic technology. I am simply taking the logical extension of the existing trends that we see in the data, combined with my knowledge of the various parts of the energy industry. Over the years I've pretty much worked in all the various bits of the energy industry (fossil and renewable and big-electrical) at a practical level, as well as having a more academic level of understanding. So that means I am able to see which stuff in the data is significant enough to extract and use.

4. When you drill the first oil well(s) into an oil reservoir you tend to get a lot of oil out to begin with, and then as time goes on you get less and less until finally it is not worth the cost of looking after the well(s) and you declare the field dead, and close it in safely (at least you should do it safely). This is called natural decline, and it happens over time with all oil (and gas) reservoirs no matter how much care and attention we give them in all sorts of complicated ways to try and stop it happening. In any given reservoir there is a natural economic limit (at a given oil price) no matter how many wells we drill into them. It is just a natural fact of life for oil & gas reservoirs. If you crunch the historical data for all the known reservoirs in the world it turns out that the average decline is 6.5% per year. I've worked on reservoirs that declined faster than that, and ones that declined slower than that, but my personal professional experience also aligns with the studies that came up with the 6.5% average number, so I'm happy to use it. So if at the end of each year we were to actually stop actively going out and drilling new wells into existing (or new) reservoirs, and to stop doing interesting 'workovers' and 'sidetracks' and 'stim jobs' and other fascinating stuff to make more oil come out, then by the end of the year there would be 6.5% less oil flowing. For each calendar year have plotted those natural decline curves in the various colours.

5. When you consider the coming years it seems that by about 2030 nobody will want to drill any more wells at all. Not ever. By then the oil industry won't even be able to stimulate extra demand through its natural mechanism of lowering oil prices. Normally lowering oil prices mean that magically Americans go out and buy bigger vehicles and consume more, and so does everyone else in the world. But by 2030 as far as I can see the bigger truck wil be running on electricity, and so will the bigger aircon, and it will increasingly be supplied by renewable electricity. So somewhere about 2030 the OPEC/etc countries will conclude that if they don't use their standby wells (and fields) now, they'll never use them, and the game of chicken in OPEC will really be on. And by 2040 it will be completely game over for oil, and everything will be running on non-fossil energy : mostly renewables with a small amount of nuclear, etc.

6. I find it interesting that my models of EV curves, battery curves, and energy are all giving me very well aligned results. If the energy model was saying full transition by 2030 but my EV model was saying that transition would take until 2050 then I'd recognise that these were contradictory answers. But instead they are in very good alignment with pretty much game over for dino-juice vehicle manufacturing by 2030, and then end of fossil fuel production about 2040. That gives just enough time for the very last dino-juice vehicles to do about 10-years useful work between coming off the production line in 2030 and literally having no fuel available in the market in 2040.

7. The amount of effort going into drilling all those wells to overcome the 6.5% decline curve; and to building new oil & gas facilities (because they do wear out); and building new oil/gas/coal power stations; and shipping, and so on (because it all wears out) is very significant in industrial, financial, and economic terms. The point is we are already doing that. So in my model I quantify it and that effort gets progressively transferred across into building the renewables & electrical infrastructure. In fact that sets my maximum 'speed of transfer' constraint in my model, so I know that what the model predicts is realistic and achievable. This is already going on - it is now cheaper to build a new solar farm than to run an existing coal power station - so all my model does is use the existing data to make that trend explicit.

8. Collectively we've been working towards this since the 1970s or earlier. I grew up in a house in the 70s stuffed with books written in the 50s and 60s about these issues. But really it was the 70s when things became serious* and so it is fantastic to see it finally coming to fruition after 50-years of human effort. The next 20-years are going to be literally transformative. What remains to be seen is whether this is going to happen fast enough that we can escape the consequences of the damage we have been doing, mostly in those same 50-years.

Hope that helps.

It is likely profitable since there are companies already doing it. Take a look at lead acid battery recycling for an example of a mature industry. And if by some miracle it wasn’t profitable, then governments would make it profitable through mandates and recycling fees.

One more thought on this.

So far we’ve seen Tesla opening up only their smaller sites with lower utilization.

Tesla can use this as a way to boost utilization while not sacrificing the experience for Tesla drivers. The new sites with more stalls and higher volume can be Tesla exclusive until Tesla has expanded capacity enough where they can support the various other makers at all their sites.

If Tesla is getting subsidies for installing these devices, it’s a huge win for them with very little downside. They can keep converting sites which are in lower use areas and collecting subsidies while not hurting their own customers.

This isn’t like some dumping ground where CCS users only get the cast offs either. There are a lot of locations where it’s necessary to have a charger, but utilization is not super high.
 
Second, waiting till Biden folded after realizing the only way to get even close to his charging infrastructure target was if Tesla did most of the heavy lifting.
  • This put Tesla in the dominant position for negotiations resulting in the retrofit of existing SpC kiosks qualifying for the subsidy.*

There is no subsidy for what Tesla is doing now. For a number of reasons:
  1. The money is issued via the states/territories via a RFP process. (i.e. Biden can't direct the money anywhere, specific unless the states agreed.)
    1. No state has issued the RFP yet. (So Tesla can't have applied/been granted any of it yet.)
    2. The first NEVI funds are likely to be granted this fall. With construction starting next year.
  2. The money is only for future projects, it can't be used to fund something already built.
  3. As the Magic Dock has been installed it is likely not NEVI compliant, to qualify for any of the funds:
    1. Are the locations NEVI approved? (Within 1 mile of an AFC and being ~50 miles from the next closest NEVI AFC site.)
    2. It requires that you download the Tesla app, that is not allowed.
    3. It requires you to create a Tesla account, that is not allowed.
    4. It doesn't allow you to activate/pay through a third-party provider. (Think ChargePoint, Blink, Ford Oval app, etc.)
    5. It doesn't allow you to pay via a dumb phone.
    6. It likely can't meet the minimum power requirements, minimum of 150kW on any NEVI funded stall anytime a car asks for it.
      1. A normal full V3 site can only provide ~83kW per stall.
    7. Tesla hasn't opened their real-time stall usage data to any third-party that asks for it.
    8. Some states/territories may require on-site physical credit card readers.
    9. Some states/territories may require on-site physical displays.
    10. Some states/territories are going to require Plug&Charge support.
    11. MagicDock may not qualify for NEVI funding as it isn't really a permanently attached CCS Type 1 connector.
Of course, Tesla could likely resolve all of those issues, a lot of them are just software related, but may also require grid/transformer upgrades in addition to additional V3 cabinet installs and rewiring. But they would have to wait until they were approved for funding, and they may not want to wait until next year to get started. (And they may not want to comply with some/all of the requirements.)

*I made some assumptions that the retrofits of SpC's get the same subsidies as new installs. If anyone knows otherwise, please advise.

Yes, upgrades to be NEVI compliant would get the same subsidy, which is 80% of the cost of what is submitted in the proposal. So, Tesla would be eligible for 80% of their cost of making them NEVI compliant. (Not 80% of the complete cost of the site's original build cost in addition to the upgrade cost.)
 
If you have no factory and the choice is to buy an empty factory or build, then building is the easy choice. For Tesla, it’s a simple problem.

For legacy, there is billions invested in existing infrastructure which makes it a lot trickier. Particularly since they have declining sales with no easy way to reboot those declining sales. All the options are all pretty bad. As you suggest, the layout and equipment aren’t ever going to be quite ideal for EVs, but a lot of it is still required and very expensive to move.

While Fremont isn’t as optimized as Shanghai, Berlin, or Texas, it is still massively profitable. If VW could take their existing factories and equipment and make something nearly as efficient as Fremont without investing $2-3 billion on a new facility, it would be a huge win for them short term and maybe serve as a bridge into the longer term.

I think US legacy automakers have a different reason altogether to create new factories. By moving to a different state, I think GM and Ford can open a new facility and escape many of the union obligations their existing factories have.
That also means idling an existing factory (along with those workers, and if they are union you might be paying them to not work) until you can complete the upgrade. That's a lot of opportunity cost.
 
The key with buybacks is that they buy back + cancel shares and actually give current investors more ownership of the company.

But that is not always the case, and this is something Buffett has also talked publicly about. With some companies, more commonly in tech from what I had read, buybacks can be executed but then the company adds far more shares through new options particularly through stock-based compensation plans. You need to understand the full picture to really know whether you're getting more equity as an investor or whether buybacks end up being a tool to allow further dilution through stock options.
In the case where buybacks do not cause the option grants to grow EVEN MORE than the buyback, they are anti-dilutive. Less dilutive than no buyback.

In the case where they increase the option grants the exact same amount as they buy back, then they are neutral.

Only in the weird case where the company decides to issue more than they buy back over and above the grants they would have issued anyway, would buybacks be net dilutive. Can’t conceive of this happening.

Not what I see really. Buy backs force investors like me to sell shares. Not what I want. If a dividend then I can make my own choice as to whether I buy even more shares or use it as I please. I see buy backs as heavy handed. At least a balanced plan would show some thoughtfulness IMO or don’t do it at all.

It is not all about tax avoidance for everyone. And I like Buffet’s business approach generally but I also would not be surprised to see it change.
Imagine you own enough shares to constitute 100 billionth ownership of the company.

Scenario 1: 2% dividend
Result: You own 100 / 1B of the company plus get 2% cash

Scenario 2: 2% stock buy back

Result you now own ~102 / 1B of the company.

Option 1: Sell 2% of your shares:
Result: You own 100 / 1B of the company + 2% cash (Identical to dividend scenario. Fewer shares, but identical ownership)

But now you also have Option 2, which is to sell those shares in the future at a possibly more tax advantageous time.

All that matters is percentage ownership of Tesla, not the share count.

I am in the camp of those expecting that Investor Day will be about Master Plan Part Troix, i.e. how to scale for a global transition to renewables. So far, I abstained from such speculations but @wdolson wrote in a post in the Russia/Ukraine thread [emphasis mine]:
Europe has some pretty significant challenges converting completely to renewables. I don't think they can do it without also adopting nuclear power.
[...]
The cost of installing enough renewables to serve all of the UK at a level of 50KWH per person per day had dropped from 93K Euros to 18K Euros.
My immediate reaction was like "We're a household of 3 with an electric car and we use less than 15kWh per day on average. This 50kWh number has to be the entire country's consumption divided by # of UK citicens".

Living in Germany, I was curious now how my personal use of electricity compares to the entire country's consumption divided by headcount.

Gross electricity consumption in 2020 for Germany was 559 TWh per [1]. In the same year, Germany had 83.1 million residents.
That equates to 559 billion kWh / 83.1 million / 365 = 18.45 kWh per person per day or about 6.700 kWh/year.

According to [2], private households consume about one quarter of all electricity and other sources saying that the average private use of 1300 kWh per year and person corroborates that.

Renewables contributed 246TWh or about 50.5% of electricity generation in Germany for the year 2020 (down to 47.5% in '21). Renewables need to roughly double in order to fully replace non-renewables. Btw, nuclear contributed 12.5% in '20 and 13.3% the year after.


All of the above is just the tip of the iceberg if we look at overall energy consumption. According to [3], Germany's gross overall energy consumption in 2020 was 11.504 PJ (Peta Joule). According to [4], industrial use was 3.747 PJ, out of which 12% or 448PJ were used as feedstock to chemical processes. If we put these aside to be tackled later, this leaves us with 11.056 PJ used for energetic purposes. To get the delta, we can also subtract half of the 559 TWh = 276,7 TWh renewables. We all know that 1TWh = 3.6 PJ. With that, I calculate 996 PJ of renewables in '20 and a remaining 10.060 PJ of fossil (and nuclear) sources to replace.

As we're talking about gross electricity, we can assume 100% efficiency for renewables. For fossils, efficiency varies widely. Thermal power plants can have a thermal efficiency around 40% and more if waste heat is used for heating purposes. In everyday use, cars tend to be in the low 20s if one doesn't go with official but looks at actual fuel consumption. A lot of gas is used directly for heating, be it domestic or in industrial processes. Heat pumps produce between 2 and 5 times the invested electrical energy as heat.
With considerably more research, it might be possible to calculate how much electricity would be needed to replace all fossil energy but an average factor of 33% should be at least in the right ballpark.
With that, we have to generate an additional 10060/3 = 3353PJ = 931 TWh of renewable electricity to match Germany's energy consumption in 2020.
TL;DR; Renewables covered about 21% of all energy needs in Germany in 2020 if we assume that 1 kWh of electricity can displace 3 kWh of crude fossil energy. In other words, we need about 5x of today's renewables for a full transition.

Is this achievable? I did not investigate but there's a lot of untapped potential for onshore wind, domestic and grid-scale PV and offshore wind is only a matter of funding.

How many batteries will be needed?
Tony Seba calculated 110 hours of storage for a least cost solution at 400 GW of installed renewable power [5]. We had 63MW of wind and about 50 MW of PV in 2020. If that were equally scaled by 5x, we may need less storage. Vice versa, his demand for 400 GW looks reasonable with additional storage in place as surplus capacity today gets sold or wind power is shut down.
Therefore, I won't come up with my own calculation but consider his 6.2 TWh demand for storage (in Germany) to be a good estimate. As he demonstrates, the amount of storage for a least-cost solution depends on local availability and variability of wind and solar. Therefore, it's not easy to extrapolate global demand from the case studies in his presentation.

My hope is that investor day will be used to share Tesla's plans for this decade and the 2030s with respect to installing production capacity, sourcing raw materials and how to address any other challenges that they identified.

That also means idling an existing factory (along with those workers, and if they are union you might be paying them to not work) until you can complete the upgrade. That's a lot of opportunity cost.
It’s all weird either way.

VW almost certainly has a lot of idle capacity right now due to lower demand. Do they continue running 10 factories at 80% utilization and while they build another factory? Now they have 6 factories working at 66% production.

Probably the ideal solution right now has more to do with finding the quickest way they can transition capacity to producing (desirable) EVs. I don’t think we can answer that easily.
