A lot of the assemblers and things like electric furnace or electric incinerator; instead of accepting a module or fuel to increase productivity, now require fuel to work (aside from electricity). Got my saved game completely stalled when tried to enable this mod, LOL.

The aim was to replace all crafting machines' energy sources to burners so that everything runs on solid fuel instead of electricity and better fuels replace modules. If you want to retain the original power sources you can comment the for loop in data.lua that changes it.

Ah! I misunderstood the Mod's intended behavior, thinking that burnable fuel would increase efficiency on top of its normal power source. I will try that change sometime next week.
Thanks for the response and hope to give your mod a good ride soon :D
