My sim was growing out of control, so I started jacking up the costs for everything. Interestingly, sim was loosing energy at the same rate (very slowly) no matter what the costs were. So I set them all up at 10,000 and still the total loss of energy in the sim was ~60 per turn. Strange. Check it out. Especially take a look at huge veggies on the right side - they have massive bodies, but even though they should be charged 10,000 per body per turn, they are not loosing energy.
