Basic economics already says we will never run out of oil. Sure it may be $10,000 per barrel, but it will still be available.
Actually, it reminds of a housemate I once had who often ate other people's food. He would respond "Well, you can help yourselves to the food in my cupboard"... which was, in total, one lemon and a quarter-kilo of flour.
You walk into the store that sells things. You go up to the meat counter, and you say, "I want a kilo of meat." They weigh out your kilo of meat, and give you a receipt that says, "Meat: 1 kilo". You then go to another counter, where you pay the clerk for that particular receipt - it is then marked as 'paid' (or you get another one, I forget.) You then go back to the meat counter, and you give them the "I paid for this" receipt, and then receive your kilo of meat.
So, at best, you've got two inefficient checkout clerks! And at worst, you pay for meat and then there is no meat.
It's not like we actually need that land to grow food on or anything.
Sure, the sun is finite too. But the idea here is to speak in terms of human experience, not literal truths
I think that would be enough time to figure out fusion. Or put wind and solar everywhere.
But we seem to be stuck, paralysed in our fight to solve everything with impossible requirements.
Fight AGW, NO nuclear, and keep the standard of living (or even increase it). All at the same time.
Personally, I would rather relax the second requirement.
