This paper is an attempt to interrogate and examine the unstoppable short fall of energy which has been paralyzing the life of Karachi for decades. The monthly data for the period of Jan-2009 to Dec-2011 has been interrogated while using the Pearson correlation, Vector Auto regression (VAR) and Tobit model, to conclude the bottom line. The findings reveal that there is a vast difference between the actual demand and actual supply of energy i.e. energy shortfall for the various segments of Karachi city which include house hold and industrial consumptions both, and such overwhelming gap causes Load shedding for every now and then, and made the life of this city even difficult but this load shedding to overcome the stated gap does not reduce it empirically and historically. The paper also confirms that it is the short fall which decides the per unit price of energy use for both the households and industries.
