It's times like these that I really wonder where all the oil peak guys are who you used to see crawl out of the woodwork whenever anyone talked about oil. Now they're suddenly quiet. They used to predict doom and gloom due to an oil shortage, but what we got instead was doom and gloom and an oil glut. Where are they now?
Hubbert peak oil theory seems to not really hold water in retrospect. People try to say the peak is just delayed as we're finding more oil reserves or because there's been a big switch to renewables. I think his models assumed a very different metrics for oil supply and distribution that don't seem to apply today. This podcast from a few years back goes into a lot of it: https://youtu.be/0wlNey9t7hQ
We'll see if the shale gas boom is sustainable. The oil prices required to make it profitable are not comfortable. It isn't obvious to me what the 'new technology' here was beyond prices being very high in 2010. We'll be using a lot less oil at those prices.
