It's 100 MJ/t for 4 so I would assume ~250 EU/t.So basically use biofuel or fuel, I mean I have a ton of oil backed up in tanks that I can refine and throw in some boilers for extra power. How much EU/t does it take to get one of those laser drills going? (4 prechargers)
E: Derp that's for 1. So ~1000 EU/t per fully powered laser.
