The Emirates Economist says it very well:

Iran's oil usage is growing at the fastest pace in the world. Its capacity to produce oil is declinging rapidly, and its reserves could be depleted in a decade.

I guess those in charge are focused on short term contentment of the domestic population. Nuclear power will not be able to replace all the domestically consumed oil. But nuclear weapons might.

Iranian prices for gasoline are so laughably low, and Iranian refining capacity is so comparatively small, that Iran imports refined gasoline at considerable expense. How the current leaders expect to cope with the anticipated future shortages due to this grotesque under-pricing is anybody's guess, but being able to threaten neighbouring oil producers with nuclear anihilation might be one possible strategy.

As I have written before, it might be a good idea for Canada to develop nuclear weapon capability itself.
