Physical modeling and computer graphic simulation of the depletion of world energy reserve

A physical modeling device and a computer graphic simulation program of the depletion of world energy reserve are developed to demonstrate how rapidly our energy reserve is depleted, how quickly and enormously our demands for energy grows, and how important energy conservation is to us. In both modeling and simulation cases, the total world energy reserve, the current energy usage annual growth rate, and the current energy consumption rate are given as parameters. One can view the energy shortage in terms of the rapidly falling levels in the physical water tank or the simulated oil barrels.
