There doesn't seem to be a way to check your energy level in the future (or past). The only way to check when you will run out of energy is to fast forward until you see the blinking lights. This makes it difficult to plan actions that involve moving/promoting tinkerers, power stations changing ownership, or changing production rates.

It would be helpful if your total driller count and energy level were displayed as a part of the main UI, rather than just the intelligence report, which can't be opened while using the time machine.

I agree, this can be a pain. Neptunium counts are also hard to predict, and it's a hassle to plan an attack when you don't know what your driller production will be.

On the other hand, though, the game is based off the idea that you don't have all the information. Even though this isn't the same as misinformation, it does add a random element to the game, in my opinion.

it's on our list to add graphs for these things (including projected values into the future)
