Oh boy... Well assuming you can make it back to your universe one day with your memories of this place intact, I might have just the thing you guys need then.

Because, see, where I'm from we can refine energon from just about any source of energy. That's why Earth was such a big target; it's got massive amounts of energy resources. Our Megatron's original plan was to drain it dry to repower Cybertron.

I could even show you how to put together a basic refiner after you've recovered from the massive hangover you'll inevitably end up with tomorrow after consuming all the high grade you ordered. Most of the parts we'd need aren't that hard to find, and the ones that are, I can ask Wheeljack about.
