Hello Midnight1131 - it is quite probable that oil will still be pumped out of the ground in 100 years. But I would place my entire bank account balance down right now as a bet that Peak Oil will occur before then.
Yeah, I think they like to say that oil won't even last 20 :P. But personally, I think big oil already has a plan for that. I mean, they spent years killing off Tesla vehicles and drowning other electricity products in paperwork that if you were smart enough you would keep a record of that tech for a rainy day. In that case, they'll probably pump every last dollar out of oil before they miraculously switch to electricity and save the day, I would not be surprised one bit.
