Forum:Energy Link not there?

Hey, I'm trying to learn how to use Technic using the Technic launcer, just messing around with stuff, I've got up to wanting to power my stuff by solar. I've built a small system that's working well for powering machines on site, but I wish to use power teleport pipes so as to not have loads of messy pipes all over the place. I've looked on youtube and they all seem to be using an energy link connected to the MFSU, but... I can't find an energy link anywhere. Has this system changed now or something? Could someone point me in the right direction as I'm currently going into information overload reading through all the pages on the wiki about energy xD
