Universal Electricity Mod is undoubtedly one of the best mods ever made. Well, it’s not actually a mod, but rather an API, whatever. The point is, the mod/tool adds a very modern feature to the world of Minecraft: electricity.
You heard it. The tool itself is an energy provider. If that doesn’t make you want to install it right away, let me tell you something: it provides all other mods with its electricity; and the mods that use this tool will be compatible and able to communicate with others!
The tool is a fairly new one, so right now there are not that many mods that use it. However, I suggest that you install it anyway, because judging on how cool it is, more and more mods using the tool will appear.
