Ok this is not completely on the topic but still related if/when the number of electric cars increase significantly. It also gives a slightly different view on the whole conversation.
This is free quote based on my memory from a blog/article from CEO (or some other high level guy) from finnish oil refinery company Neste (our local texaco) that I read some time ago. When refining oil, only 8% of crude oil can be transformed into aviation fuel. The rest goes into gasoline, diesel and all sorts of lubrication mainly used in applications requiring internal combustion engine. I would imagine that we are quite far from electric airplanes and the traveling with an airplane is not going to end anytime soon? Therefore if electric vehicles become significantly more popular, we will have vast amounts of excess fuel available and practically nowhere to use it... or maybe we have, in our gas gusling big blocks
So according to this theory, the fuel prices should drop based on supply and demand which would probably make the combustion engine based cars more appealing again.
Seems like its "on topic" to me .. but we'll see what the other folks think
I don't think an electric plane is in our immediate future ... except for very small prop planes, they're too heavy to use batteries (which exacerbates the weight issue) instead of aviation/jet fuel. Jets? I just dont see it at all.
So for earth-bound vehicles, I think this is an interesting question and I think economic theory supports what you read about from Neste CEO
.. BUT all depends on how people (governments, consumers, producers) will really behave given the circumstances they face.
For example, when supply of something increases/demand decreases, prices tends to drop. Excess gasoline supply -- IF demand/supply "curves" structurally shift (meaning refiners PERMANENTLY go out of business vs TEMPORARY cutbacks, and/or consumers PERMANENTLY turn away from gasoline and go to some other fuel) -- will mean gasoline prices PERMANENTLY go down (with a few exceptions -- the diehards/unfortunates who STILL need it will pay ANYTHING for it).
In THIS hypothetical, why would consumers
permanently move away from gasoline? Why would a driller/refiner
permanently retire capacity? Those are debate questions that make this an interesting topic.
My "two cents'?
Absent running out of OIL, or LAWS that outlaw gasoline, or TECHNOLOGY for an electric that gets 800 miles per charge, recharges in 5 minutes emerges, etc.,,
OR finding a proven 100,000 year supply of oil, or an ICE V8 getting 100 mpg and deliver 400 HP, etc, I only see us SLIDING ALONG along demand/supply curves -- i.e., TEMPORARY price movements up/down. No "shifts" of the curves for gasoline.
lets see what the other folks think. again, i liked your question. THanks!
