7.24: The Energy Cycle
Figure 1. In the carbon cycle, the reactions of photosynthesis and cellular respiration share reciprocal reactants and products. (credit: modification of work by Stuart Bassil) CO 2 is no more a form of waste produced by respiration than oxygen is a waste product of photosynthesis. Both are byproducts of reactions that move on to other reactions.

Battery cycle life vs ''energy throughput''
Energy throughput is the total amount of energy a battery can be expected to store and deliver over its lifetime. This term would be especially useful written into the warranties of all battery products. Let''s say the example 10kWh battery bank mentioned above has a warranty on its throughput instead of its cycle life.
