Those poor Iranians
I suggest you try to analyse the data. Iranians have a very high energy usage per capita - at least as high as any EU country and probably higher. The country is a major oil and gas producer, and the population is accustomed to cheap petrol prices due to heavy subsidisation by the government. You won't find many Iranians opting to use public transport for the good of the environment. Like Americans, they would rather sit in their own air-conditioned vehicles in interminable traffic jams.
