With the current circumstances which have caused the low price of diesel in Iran, the necessity for a comprehensive evaluation seems more obvious.
Some countries took policies to significantly reduce fuel consumption, such as policies in 1994 in the USA which failed .
Total consumption of petroleum products in 2016 was estimated to be more than 70 billion liters, which had an approximate value of 25 billion dollars with a share of 35.5% and 40.6% for gasoline and diesel, respectively.
Gasoline consumption in 2016 had an average of 71 million liters per day with 2% growth compared to the previous year.
This paper found that only 21 percent of cultivable land is needed to replace the diesel currently consumed in Iran with microalgal biodiesel.
Fossil fuels demand has grown faster due to economic development and the increase in the world’s population [1,2,3,4].
During this year, diesel consumption had an average of 81.2 million liters per day with a 19% decrease compared to the previous year.
That decrease was due to the delivery of natural gas to power plants and sugar and cement factories, as well as more control over consumption and the prevention of smuggling of this petroleum product in the non-power sector.
Among the fossil fuels, diesel has the major share in petroleum product consumption.
Diesel demand in Iran has increasingly grown due to the low price of diesel, a high subsidy, and an unsuitable consumption pattern.
