I heard Yergin interviewed on public radio yesterday, and they discusses a lot of the stuff.  To be honest, I had never heard his arguments presented except by critics, so it was interesting to see how he described it.

In the interview they did ask him about comments from Simmons and others.

He still thinks the Saudi's can produce 14m bpd.  I didn't hear him talk about depletion - he only talked about upside potential - he mentioned that many oilfields end up producing more than originally predicted.  Then he tried to sprinkle some fairy dust and talk about how technology could come along and change everything.

Here is the link to the show I heard, On Point at WBUR:

On Point interviews Daniel Yergin
I'm listening now, and I am so tired of being advised to lower my thermostat.  We kept the house cold last winter and still paid lots more than the winter before.
Thanks for the link.  The host quoted extensively from the Hirsch report, but, amazingly, Yergin seems to have never heard of it.  Yergin also claimed that the IOCs are reinvesting their profits in new exploration, when they are actually using them for stock buybacks and M&A.
