-* When considering fuel sources for [[Thermal Power Station]]s, due to the 20% inefficiency, [[Energetic Graphite]] comes out slightly behind the equivalent of two Coal, with a net loss of 55.25 kJ per Energetic Graphite in the optimal situation of using [[Sorter Mk.III]]s with [[Sorter Cargo Stacking (Upgrade)|Sorter Cargo Stacking V]]. Manually loading Coal into a [[Smelter]] and unloading Energetic Graphite before manually loading it into a Thermal Power Station results in no net difference in energy generated.
+* When considering fuel sources for [[Thermal Power Station]]s, [[Energetic Graphite]] comes out ahead of the equivalent 2 Coal, with a net gain of 446.4 kJ (558 kJ in the mech) per Energetic Graphite using any [[Sorters|Sorter]].
-* When considering fuel sources for the Mecha, Energetic Graphite comes out slightly ahead of the equivalent of two Coal, with a net gain of 123 kJ per Energetic Graphite in the optimal situation of using Sorter Mk.IIIs with Sorter Cargo Stacking V. Here Coal also loses out due to energy density, with a full Mecha fuel chamber holding 1.08 GJ of energy with Coal, while holding 2.52 GJ with Energetic Graphite, which will also release its energy at a 60% increased rate.
+** 2 Coal have an Energy Value of 5400 kJ. Energetic Graphite has an Energy Value of 6750 kJ.  1350 kJ are gained.
-* As such, Coal should be burned directly by Thermal Power Plants, while being smelted into Energetic Graphite for use in the Mecha.
+** To smelt the coal requires 1 [[Arc Smelter]] running for 2 seconds, which costs 720 kJ.  There is still a 630 kJ gain.
+** To move the products to and from the smelter requires 2 [[Sorter Mk.I]].  Running 2 Sorter Mk.1 for 2 seconds requires 72 kJ.  There is still a 558 kJ gain.
+*** If [[Sorter Mk.III]] are used instead, the cost is the same.  Sorter Mk.III uses 4 times as much power when running, but runs for only 1/4 time.
+** The energy to mine the two coal and insert fuel into the thermal plant is the same.  The thermal plant sorter actually runs only half as often, which will increase the energy gained.
+** Due to the 80% energy efficiency of the Thermal Power Station, only 446.4 kJ are gained.  In the mech, the full 558 kJ are gained.
+* When considering fuel sources for the Mecha, Energetic Graphite comes out slightly ahead of the equivalent of two Coal, with a net gain of 558 kJ per Energetic Graphite using any Sorter. Here Coal also loses out due to energy density, with a full Mecha fuel chamber holding 1.08 GJ of energy with Coal, while holding 2.7 GJ with Energetic Graphite, which will also release its energy at a 60% increased rate.
 * Coal burns for 1s in the Thermal Power Station, consuming 60 Coal per minute
 ** 2.7 MJ * 0.8 fuel efficiency / 2.16 MW = 1 s
