This is a chart from the Energy Tomorrow blog. It shows the most recent US Geologic Survey of oil reserves in North Dakota. Oil & Gas production is one of the biggest economic success stories of the past decade. And you know what, the US is doing this with one hand tied behind its back since much of the East and West Coasts are off-limits, California has shale oil that is thought to dwarf North Dakota's and much of Alaska is also forbidden territory.
Every decade or so someone tries to scare the world with the idea of peak oil. The idea has been around as long as oil, and always wrong.
The thing about oil is, when prices go up, more is found. $100 per barrel oil encourages greedy people to find oil with hydraulic fracturing or mine oil sands.
The other thing about oil is, when prices go up, demand goes down.
So it will be a long long long long log time, if ever, before the world runs out of oil. If oil prices go up, more is found and less is consumed. The only thing that can mess this up is bad policy decisions.
God bless the poor folks at Climate Progress. They keep trying to convince us, or themselves, that oil is running out, or too expensive, or too dangerous or makes too much money, or too little money or something. This is there latest.
