Yeah thats why it would have to be very expensive to use and make. By the time that you can make it you'll already have quarries, mass amoutns of resources, etc. Once you hit a certain point, theres not much need for mining, so end game mining should be more able to go after specific ores and such that takes more precise work than a quarry or anything could do. So instead of blindly mining with your high tech mining tools, you could instead look for specific things that you may need. It would be WAY overpowered if you could get it low tech, but I'm talking about something that will drain more eu than you would usually use at lower levels and would cost mostly the highest tier stuff that gregtech adds.
EDIT: Also is the industrial electrolyzer supposed to be taking energy when theres nothing in it? >.>
