Oil remains the driving force of war, proving itself a vital component to waging a prolonged conflict. For the purposes of the GFP ranking, oil consumption is applied as a penalty to each nation, the lower its consumption the better. Oil consumption is used in conjunction with oil production and proven oil reserves.
How does Oil Comsumption factor into the final GFP ranking? Despite our advances in battlefield technologies, oil remains the lifeblood of an army - without a healthy supply, mechanized forces can accomplish very little. However, the larger one's army forces are, the greater the demand for oil reserves. As such, the GFP formula takes this into account and penalizes all nations based on the total number of oil consumption. The less reliance on crude, the better - and the smaller the penalty.
