i've been thinking, mostly when i build stuff, i can wait for more than 20 minutes than get all my stuff together to strike something, at this time, it's using a lot of energy.
If we can make a auto control of our power plants to shut off when not needed and turn on when we are getting low on energy, that can save us a LOT of metal and crystal.
We know that mk 1 power plants are the most efficient, and the least generating power too.
So, if we have a excess of 6500 energy ( mk 1 generates 5000, mk 2 generate 40,000 mk 80,000), it will auto turn off our mk 1 power plant, and generating it back online INSTANTLY when we get new ships or something, that will also mean that our energy balance should always be under 5000. i know that -2 metal and crystal is not a lot, but count a lot of them plus a lot of time, you could save a lot of metal and crystal without doing anything else.
Let's say we have a excess of 11000 energy, turns of at most 2 of your mk energy reactors and only one if you have only one
If we have 38500 energy but you already turned off 1 mk 1 power plant, it will automaticaly turn on the mk1, and turning off the mk 2, CAUSE mk 2 isn't as efficient as mk 1s
so on..... it will choose the most efficient way
Low power mode, everything that isn't doing anything will be turned to low power mode automatically, and will save you energy and thus, saving you a lot of metal. it will of course turn on when it's gonna build , fight or anything, and anything that you can't afford t o turn off at any given time , well you can program it not to,get a nice energy boost and get a extra 2, or even 50 metal PER SECOND
