Coal Vs Alcohol

[kalos72]

Seeing as I am back to doing some work on my campaign, I seem to have alot of questions lately.

Using the Pirates of Vistula module as a baseline along with the x2 coal and X3.3 Ethanol Fuel Energy tables from the T2k core rules, I am thinking which would be better to convert say a river barge like the Wisla Krolowa too given you have access to both types of fuels?

Coal has a higher co-efficient but needs different storage since its a solid fuel vs a liquid so thats more systems that need converting.

Alcohol wouldnt need the fuel system conversion but it requires using crops that could be used for feeding the population instead and more overall energy because of the lower energy.

Perhaps coal would be better suited for energy production on land versus powering a ship?
