Article in elektrek about ebuses is Shenen. Interesting that 16000 buses is 345,000 tons of oil, which equals about 2mm barrels. By 2020 the Shenzhen model will be in process of repeating in all China super cities and china will likely start funding exports in Africa and other strategic trading partners. These buses may be more highly utilized than many cities would, but basically every 8 to 10,000 buses displaces 1mm barrels of oil. Semi trucks should be about the same.
10,000 buses = 1mm barrels annually (bpy)
10,000 truck = 1mm bpy
125,000 cars = 1mm bpy
Jhm had a model to estimate how much oil is displaced vs how much new demand is reduced. If 60% of vehicles replace old and 40% are new modeling ev impact gets pretty simple.
1 bus = 12.5 cars = 1 truck
2018 projection
1mm cars + 100,000 buses + 0 buses = 18*.6=10.8mm bpy displaced and 5.2 million in new demand avoided.
2020 cumulative sales
3mm cars + 300,000 buses + 10,000 trucks = (24mm+30mm+2mm)*.6=33.6mm barrels per year
Am I underestimating total ev car sales? Who else is making lots of ev trucks? Hardly bending the needle in 2020, but the numbers start going up much faster after 2020 when the 50% yoy numbers start getting big.
I like this. You're underestimating 2018 EV car sales but you have 2020 sales about right.
My model for EV car sales is a simple 40-50% YOY growth model based on the total worldwide plug-in sales as reported by InsideEVs (there are obviously year-to-year fluctuations), but basically we're at 1 million per year in 2017, and should be at 3 million per year in 2020.
I don't have a particularly good model for buses or trucks. I think buses will exceed the growth rate for cars, but I can't get good numbers on *current* electric bus sales! And trucks -- really it's Tesla, BYD, and nobody else, but neither is selling in high volume yet, so I don't have a good projection for when they will. Tesla's reservation numbers may be our best starrting point.
So using your model, in 2020 that year's sales of EVs eliminate about 1/1000 of global oil demand. But I don't trust the 60% factor. I'm going to run with a 100% factor. The interesting question for me, then, is when this number exceeds the growth rate of oil demand from other causes, thus causing dropping oil demand.
If we assume an average 4% YOY growth in the vehicle fleet, it would be 2028.
(4% seems to be a slight overestimate for passenger cars and more so for commercial vehicles, which are more like 3.5%.)
By 2030, the drop in oil demand exceeds the decline rate of the oilfields and it becomes unprofitable to ever drill another well.
This is too late an estimate for many reasons. First is that newer gasmobiles have better mpg than older gasmobiles being retired, which I have completely ignored. Second is that higher-miles-driven-per-year vehicles will be replaced with electric preferentially, frontloading the reduction in oil demand.
Third, I don't know how to estimate the reduction in oil demand from heating, electricity, and & industrial fuel shifts. It is probably substantially less than the shift from transportation but it will pull these dates forward somewhat.
Fourth, I actually don't think my 50% YOY growth model keeps working for the next decade, because at some point capital pours into the electric vehicle business in real volume, and the shift accelerates. This will also pull these dates forward somewhat.
Finally, of course, political policies can have an effect. They tend to "follow the parade" rather than leading it, but we're already seeing them happen, and I predict we'll see more by 2025. I just don't see it taking until 2030 for oil drilling to turn permanently unprofitable; it'll be a few years before that.
