Help! I have too much energy


Congratulations! You’ve hit that point in Screeps where your energy generation is overflowing. You have achieved total economic success… or have you? I’m sure you can do something with all dat energy!

So what to do with this abundance of energy? Well, there are 4 options for this once you’ve claimed all the rooms your GCL allows.

Option 1 – Sell it

That’s right! Just sell that energy straight onto the market and convert it into credits. This is a good first choice to make, since you are literally putting that energy into the bank. Later on in the game you could use it for the other options below or something else, but at least you’ll have stockpiled it for later. Making some market code is a good idea anyway, as it’s useful for multiple features which you may want to develop in your code.

Note: In times of war (across the world as a collective), the price of energy should increase as a result of supply & demand – Other players are expending their resources to build and maintain an army, build up walls, etc. You will find that the prices of minerals and compounds will increase (particularly X which is required for all war-time boosts), but you will also see the price of Power drop. Try to liquidate Power before or as large-scale conflict begins… until Power Creeps are actually implemented and change everything!

Speaking about Power…

Option 2 – Process Power

Get your hands on some power, and start processing it. You can get power either by farming it yourself or by buying it off the market (possibly with credits from Option 1). Each unit of Power requires 50 energy to process. For me, Power is the ultimate safety valve to stop your empire flooding it’s Storages and Terminals with energy and breaking your code with all the “Too much energy!” edge-cases you haven’t tested.

While this is a good catch-all option, Power is currently a useless commodity unless you want to hit rank 1 on the Power leader board. At some point in the future the devs will be adding Power Creeps which will make all that Power processing useful, but until then this is just a way to dump energy.

Option 3 – Upgrade Room

If you’re overflowing with energy then you probably know that you can only put 15 energy into an RCL8 Controller per tick. Well I hope you know that. If this is news to you go RTFM… I mean read the documentation. This is a big reason why players overflow with energy, but there is a work-around… the Upgrade Room.

Find yourself a room and make some code that will upgrade that room as fast as possible! As soon as it hits RCL8 unclaim it, claim it again (now at RCL1) and go back to upgrading it as fast as possible. There are different designs for this. Let’s have a look at 2 below:

Some players go for the “Full Room” setup as shown above, where the room basically looks like one of your other rooms, except you probably have the Storage and Terminal in optimum range to the Controller, and you have some juicy WORK creeps in the room burning that energy into the Controller as fast as possible.

Another option is to make a “Minimalist Room” which just has the basics required to upgrade the Controller as fast as possible, and suck energy from other rooms via a Terminal or by using Creeps to carry it in. Have a look at the example above from my Upgrade Room in W2N66 (high level description here).

Option 4 – Shove it all into walls!

(Thanks Revrick for contributing)

Live forever! Make yourself such a huge pain to ever wipe by walling and ramparting your bases to insane levels. At the current tick rate (almost 5 seconds) a maxed out rampart of 300m hits would take around 15 years to naturally decay!

Popular opinion is to not only build up your exterior walls to ridiculous levels, but also to rampart your key structures such as your Storage, Terminal and a Spawn. Just take a look at the rampart above on a spawn… and consider that the surrounding walls & ramparts are also at a similar number!

And that’s it! These are your options for dealing with excess energy.

  1. Funny you wrote this article today. Yesterday all my storages were full. (Not the worst problem to log into Graphana to see you have over 18 Million energy stored). But when my storages and terminal fill it creates issues up the line with resource collection. My energy harvested was down by about 400k an hour because of this. I had to quickly reimplement the GCL praising rooms to take the load off my empire. Already starting to see a drop in total reserves which was the goal. I had already tried option 2 but theat only lasted as long as my power which is now less than a few thousand. All in all pretty cool that this is my new problem.

    Anyway thanks for the article mordox!
