Well I have no car, so I wouldn't miss gas for my car.
If there were no gas heating, I would use wood.
I assume we would rely on nuclear, solar, and water for energy (in that order).
Finally, the government would have to force the oil companies that have bought up and sat on environmentally friendly patents to hand over the goods.
And we'd all live a great deal healthier and better?
My husband and the kids and I would all be out in the yard digging with shovels a lot because we'd be eating a lot of potatoes. We would probably all be living in one or two rooms of our house because we would have difficulty affording our heat and lights. I'd try to get some chickens and if the neighbors didn't like it they could STFU and have some eggs.
We've got a largish yard and decent neighbors (even though they can be kind of persnickety). We might survive if nobody got really sick.
“There are two novels that can change a bookish fourteen-year old’s life: The Lord of the Rings and Atlas Shrugged. One is a childish fantasy that often engenders a lifelong obsession with its unbelievable heroes, leading to an emotionally stunted, socially crippled adulthood, unable to deal with the real world. The other, of course, involves orcs.” ~ John Rogers
Because what you say is true, there would be diesel or a reasonable facsimile thereof. We have the raw materials, the technology, and the manpower to make it happen; it's just not economical to do so under the present market conditions.
But even in two years, I highly doubt the economy could handle the astronomical increase in prices of pretty much every good available. Even if the use of the rail system increasea, trucks are a necessity to move the freight from ports and yards, and contrary to popular opinion, nome of those companies are going to operate for free. Put that on TOP of the increase in cost of production and it's a recipe for financial disaster.
The question was what would we do NOW?
Buy a bunch of oil and oil-related products to sell once we run out, obviously.
