==== Energy change from conversion ==== | |||
Considering that 1 Energetic Graphite has 6.3MJ of energy for 2 coals used up with 2.7MJ each and that to do so you need a [[Smelter]] running for 2 seconds at 360kW to do so, and the fact that the Power Station has an efficiency of 80%, you can quickly see that to get 1 Energetic Graphite that will produce 5.04MJ of energy, you need to spend 2 Coals and 2 seconds of a Smelter for a total energy loss of 5.04MJ. So without even counting for energy loss from Sorters, you're already not even gaining energy from converting to Graphite. (6.3 MJ * 0.8 - 2 * 2.7MJ * 0.8 - 2s * 360KW = 0J) | |||
To make it worse, because Graphite has a higher energy capacity than Coal, you will need 16.67% (6.3 / (2 * 2.7) = 1.166...) more Thermal Power Stations than if you burnt the Coal directly which also mean extra Sorters on top of the 2 needed per Smelter. | |||
In the end this means you will loss at least 29kW of power for every Smelter running at full load to convert Coal to Energetic Graphite (accounting for perfect balance with sorters being idle at times, this goes up to 39kW if you assume the sorter is never idle). | |||

As for Coal-to-Energetic-Graphite above, we can do a quick math of the energy difference from converting the different stages of fuel to their next possible outcome. Note that for each case, if your system is not perfectly balance to maximize factory usage, each second spent idle is extra energy loss and the results given are only an upper bound of the best you could get but you most likely will get less. | |||
