Another book you might like is "twilight in the desert" by Matt Simmons. I agree with everything you've said regarding energy demand vs supply. Right now, US fracking has taken the pressure off the supply side, but I don't think this technology is solid for the long term. I'd hate to see long term irreversible contamination of the water table or whatever else may come about.
There is one potential saviour on the energy front, and that is nuclear fusion. Battery tech will need improvement before the transporting side can be figured out, either that or fusion powered hydrogen production will be the new gasoline.
Twilight in the Desert is a peak oil era book, Matt is dead now. He was an industry insider and an advisor to George W. I'm sure you've probably watched all the peak oil documentaries on YouTube, if so you already know all about him. You're right, no one knows what reserves are left, the numbers are fudged because sales quotas are tied to reserves for OPEC nations, and none of them want to give up market share by telling the truth. Book is definitely worth a read.
I just look after my own household, hope for the best, prepare for the worst. No one would listen if I told them trouble was coming anyway.
