My question for naysayers is a lot more simple and so far, nobody has answered me.
This requires a longer answer
I don't dislike EVs as a technology in general. I don't think this is a black and white decision of EV vs ICE vs fuel cells, even hardened skeptics think EVs or PHEVs are better in some use cases (since more and more people have now driven an EV).
I joined this site to discuss why the stock was overvalued in my opinion (especially when it was close to $200 in September and warned of institutions reducing their positions vs retail investors). One has to separate the company from the stock price in my opinion, just because I think the stock price is too high doesn't mean I dislike (or even "hate") the company.
Finally, I wanted to stress the importance of battery supply issues facing TSLA/all EVs and discuss the estimates/numbers.
I think battery manufacturing (supply) challenges were under-reported and barely discussed compared to overblown short-term challenges (fires etc.).
Without more
giant battery factories being built worldwide, there will never be enough supply for 10% (or even higher) of all new cars to be EVs. Some simple calculations assuming long-range EVs take off to illustrate my point:
100 million new cars/year (assuming demand in Asia continues to grow with new first-time buyers/rising middle class, this is likely. The current number is at 85 million new cars produced per year).
Let's assume 80 million of those are new
passenger cars/year (currently at around 65 million cars/year)
Let's assume 10% of those are long-range EVs with 4000 cells each (assuming TSLA's model of using small cells and Ah improvements/cell)
8 million cars x 4000 cells = 32
billion cells needed per year.
As we know TSLA already (as of late 2013) is
one of the largest buyers of Li-Ion cells worldwide and it currently produces just 25k or so cars/year.
And again, I'm just assuming about
10% of all passenger cars being long-range BEVs in that scenario, 90% of cars would still use older battery types or run on ICE, CNG, fuel cells etc.
You can call me a EV "naysayer", but in my opinion, it will take decades to solve the battery supply problem (unless a real breakthrough in battery tech comes along in 10-20 years...).
Somehow we have to make sure we can produce these
32 billion cells (or the equivalent in larger cells) efficiently and eco-friendly, including the
raw material supply chain.
So in my opinion, the EV "revolution" will be harder and take longer than anticipated on a grand scale (again unless a battery tech breakthrough comes along...).
I know that continuing to use a lot of oil is also very problematic (hidden military costs/resource wars over oil, oil spills, shortages in conventional oil fields, problems with "fracking" and other unconventional oil...).
There is no easy solution.
I laid out my view for a more eco-friendly transport future here (it may not please car enthusiasts as it intends to plateau personal mobility at current levels:
Open letter to the Haters - Page 4 ).
PS: If you don't agree with my numbers please let me know. More TSLA-specific battery supply numbers are in the "giga factory" thread.
