What’s the plan if we run out of oil? I mean seriously, it’s gonna happen eventually. Even if you want to ignore the science on climate change, you can’t ignore basic laws of the universe that oil is a finite resource. If we don’t have a plan for when it runs out, there will be utter chaos.
TLDR - oil might be a finite resource but gasoline is not oil and it can be renewable. But it's also a rapidly shrinking market.
The stuff can literally be grown on trees. It's cheaper to pump it out of the ground, but it's actually not much cheaper. Fuel from plants, which we farm in bulk for human consumption, can absolutely be used to create gasoline. It's also net-zero — because the plant takes carbon out of the atmosphere to create the oil and then it's simply returned to the atmosphere when your burn it.
Most gasoline in the USA contains at least 10% biofuel, and some is up to 85%. The latter requires an engine tuned to run on it, however it's possible (and is an area of active research) if you're willing to spend a bit more money to manufacture 100% pure biofuel that can run on unmodified engines. Porsche in particular has started selling a biofuel that is specifically designed to run on classic cars that were manufactured decades ago. They plan to produce something like a million gallons a month of the stuff, and it will work in basically any car. And if you have a classic car (designed for gasoline that contained lead) then it will work better than the fossil fuel you can buy at a gas station
The thing is though, battery powered vehicles are way cheaper than doing any of that. And if you really need a fuel based approach (e.g. batteries are just too heavy for large aircraft), then Hydrogen is a better option than any biofuel.
So - while gasoline can technically be environmentally friendly and is a usable source of energy for the foreseeable future, in reality it's destined to follow horse drawn carriages and steam engines, a technology some people only use for their own personally enjoyment or to preserve our history.
Growing crops to make ethanol is not particulatly green. In fact, in most existing production loops we would be better off environmentally to just burn pure gasoline than produce the ethanol to mix into it, unfortunately. Too much water, too many tractors and trucks, and way too much electricity into ethanol production to be worth what we get out of it. And the bit of carbon the crops sequester doesn't overcome it. Electric vehicles are by far the greenest option right now.
Not to mention ethanol (what the previous person kept referring to as "gasoline") is far less efficient, can only be used in high quantities on certain types of engines, and creates excessive smog during warmer months.
Don't forget that every acre of corn grown for ethanol is one less acre of food grown and when you increase from 10% ethanol to 100%, you're going to need 10x the amount of land to grow these crops all so we can pay top dollar at the pump to live in smog filled cities and get 10MPG in our vehicles.
