Whether "oil" (petroleum) or other resources:
Why and how "Peak exports" often comes before "Peak production"
Simplified but qualitatively correct overhead examples to accompany lecture

Case 1: Oil Exporting Country with Production Peak,
but with constant domestic demand (simplified/idealized)

Production 1 2 3 4 5 4 3 2 1
Domestic
Consumption
1 1 1 1 1 1 1 1 1
Net Exports 0 1 2 3 4 3 2 1 0

Notice: "exports" peak the same year that "production" peaks

Case 2: Oil Exporting Country with Production Peak,
but with rising domestic demand (simplified/idealized)

Production 1 2 3 4 5 4 3 2 1
Domestic
Consumption
0 0.5 1 2 3 4 ? ? ?
Net Exports 1 1.5 2 2 2 0 ? ? ?

Notice: "exports" peak in the 3rd year even though production doesn't peak until the 5th year.
