Speaking of geographical peaks, I will throw in 2 less well known facts. Coal has peaked in the USA back in the 90s, IIRC. We do produce more coals today measured in tonnage, but not in max. calories. In short, there are 3 types of coal (high, medium,low) and obviously coalminers went first for the low hanging fruits, that being high calories coal.
The other fact is that the US reached peak water back in the 70s. That is right, a replenishable item and we are running out of it. Now one might ask, how come when eventually it is going to rain? Well, we have been using not just replenishable rainwater, but water from the ground, what has been there for millions of years. In short we are using up the extra storage water, and that won't be replaced, thus overall we are in the red with water.
The point is here that we can have peaks in non-replenishable resources...
