Iran has the second largest proved gas reserves in the world after Russia, with 33.6 trillion cubic metres, and third largest natural gas production in the world after Indonesia, and Russia. It also ranks fourth in oil reserves with an estimated 153,600,000,000 barrels. It is OPEC's 2nd largest oil exporter and is an energy superpower. In 2005, Iran spent US$4 billion on fuel imports, because of contraband and inefficient domestic use. Oil industry output averaged 4 million barrels per day (640,000 m3/d) in 2005, compared with the peak of six million barrels per day reached in 1974. In the early years of the 2000s (decade), industry infrastructure was increasingly inefficient because of technological lags. Few exploratory wells were drilled in 2005.

Not only that, Austria now found herself estranged with the new developments within the empire itself. Beside the rise of Prussia, Augustus III, although ineffective, could mustered up an army not only from Saxony, but also Poland, considering the elector was also the King of Poland. Bavaria's growing power and independence was also apparent as she had more voices on the path that its army should have taken, and managed to slip out of the war at its own will. Most importantly, with the now somehow-belligerent Hanover united personally under George III of Great Britain, It can amassed a considerable power, even brought Britain in, on the future conflicts. This power dynamic is important to the future and the latter conflicts of the empire. The war also proved that Maria Theresa's reforms were still not enough to compete with Prussia: unlike its enemy, the Austrians went almost bankrupt at the end of war. Hence, she dedicated the next two decades to the consolidation of her administration.

What was the impact of the war on the wealth of Austria?
Answer: the Austrians went almost bankrupt at the end of war.
