from what larry johnson says here i'm thinking we have about a month until the collapse begins to be visible; 

 

I am indebted to my new friend who is an energy expert ,and currently working in the Persian Gulf, for explaining why the US is facing a very serious risk of a domestic energy crisis. If ignorance is bliss then I’ve spent my last 71 years happily believing that the conversion of oil to fuel for cars, trucks and planes was a simple process. Boy, was I wrong. The United States is facing a potential crisis surrounding the production of diesel and aviation fuel. According to this person, who has 35 years experience in the oil industry:

The U.S. does not have a month of freely deliverable diesel in a stress event. The headline EIA number shows 106.1 million barrels of total distillate fuel oil stocks and 3.631 million b/d of four-week average distillate product supplied, implying 29.2 days on paper. But that national inventory includes barrels in pipelines, refineries, terminals, regional storage, and operational positions that cannot all be allocated immediately to critical distribution hubs.
Operational estimate: applying a 45%-60% practical deliverability factor to total distillate stocks leaves roughly 48-64 million barrels of usable, allocable diesel-equivalent supply. At 3.631 million b/d, that is approximately 13.1-17.5 days, rounded to 13-18 days.

So let me explain how he reached this conclusion. Think of the diesel buffer as the gap between when supply stops flowing and when the economy starts breaking. Thirteen days is not a comfortable cushion — it’s essentially no cushion at all, because the economy runs on diesel in ways that cannot be deferred.

Diesel is not a lifestyle fuel. It moves every truck on every highway, powers every locomotive, runs every tractor during planting and harvest, and drives every piece of heavy construction equipment. When a family decides gas prices are too high, they drive less. When a freight company decides diesel is too expensive or too scarce, it cannot defer the shipment — the grocery store shelves just go empty. Diesel demand is largely inelastic. The economy cannot negotiate with it the way it can with gasoline..............more..........
