More specifically, it is obvious that the largest expenditure was petrol and oil, and this is still predicted to rank the first place, which is standing at just under 50 quadrillion, an increase by 15 after a half century. Moreover, the second and the third highest figures were natural gas and coal in 1980, at respectively 20 and 15 quadrillion.
