Compacted rock foundations are much less energy intensive than concrete. By maximizing the quantity of rock, the quantity of concrete can be minimized.
Concrete is 10-15 percent cement. Cement is typically 1:2:3 or 1:3:3 [1]. 1:3:3 is 13% cement.
Embodied energy of cement - 5.6 MJ/kg. Concrete trucks get 3 mpg [2].
Gasoline is 121 MJ per gallon. [3]
