How many Gigafactories does it take to crash oil?
I've been puzzling over the recent oil price crash and calls for upwards of $10 trillion investment in oil development to maintain oil supplies with modest growth in demand over the next 15 years. This is a huge investment for 200billion barrels of oil just tl continue the energy status quo.
So I wonder what it would take for Tesla to crash oil prices. How many Gigafactories would it take over the next 15 years? To put this into perspective, the recent oil crash was based on a surplus of about 2 million barrels per day (mbd). So Tesla needs to knock off about 2 mbd of oil demand to have impact.
Let's see how many vehicles Tesla needs to produce just to offset 1 mbd of oil demand. Suppose 42 gallons per barrel, 25 mpg for the average vehicle and 35 miles driven per day per vehicle. This amount to 30,000,000 vehicles ( = 1,000,000 * 42 * 25 / 35 ). Don't despair, one GF will support building 500,000 vehicles per year. So we need only 60 GF-years to produce a 1 mbd offset. To build 30M cars in 15 years we need and average of 4 GF. Ramping up linearly starting with 0 now and 8 in 2030 will get the job done.
I think 8 GF in 15 years is quite doable, but how does this square with Tesla's ambition to grow by 50% per year well into the mid-2020s? Growing at this rate for 15 years and starting with 33,000 in 2014 gets us to 14,450,000 in 2029. This will require 29 GF capacity and offset about 0.48 mby with a single year production.
A 0.48 mbd reduction might not be enough to crash oil in a single year, but the cumulative effect leading upto that point will also have a lasting impact. Moreover, the next year 2030 knocks out 0.72 mby, 2031 does another 1.08 mbd, then 1.63 mbd, 2.44 mbd, and so on. Inexorably, the oil industry will reach a tipping point where the price crashes and will never again be able to recover. It will take the industry a little more than a year to recover from a 2 mbd surplus, but demand was strong 8 months ago and will likely remain reasonably strong in coming years. But the situation will be relentless in the early 2030s. Demand will keep shifting to EVs and supply will not be able to curtail in an orderly fashion. The key forcing agent will be Tesla. Tesla needs only to grow by 50% per year, and it can do this one year at a time.
Oh, yes, and how much will 29 Gigafactories cost? About $145 billion. That is a far cry from the $10 trillion the oil industry needs to sustain itself.
