EMC

EMC or Energy Matter Covalence is a mechanic from the Equivalent Exchange series. This is the energy that is used in everything within the Equivalent Exchange mods. Almost everything in Minecraft has an EMC value, allowing them to be transmuted into each other. EMC can be created artificially with Energy Collectors and Anti-Matter Relays. It can be stored in Klein Stars. 
Items with EMC values will be stated in their tooltips when Equivalent Exchange is installed.
Mods with the EMC mechanic are as follows: Equivalent Exchange, Equivalent Exchange 2, Equivalent Exchange 3 and ProjectE.
