The consumption is not merged and will tell exactly how many packets leave trough the CN. The AC production is merged but the reserve is not.

So CN 1 needs to produce 1 AC per sec to satisfy the demand off all structures and weapons connected to it.The total production for CN that are connected is merged, and the energy reserve is also merged. If the bar is red it tells you how much demand per sec is not supplied. The bar with numbers on it tells you your reserve. The small green +x.x numbers are your energy production per sec. This panel is one of the most important elements of the game. Be careful with this one, invisible creeper still kills. Show Creeper/AC - Toggles the visibility of creeper/anti-creeper. Show Air Units - Toggles the transparency of air units (Strafers and Bombers), again useful to turn off in a big assault to manage the ground units. Show Mist - Toggles mist animation when creeper is killed, useful to turn off during big assaults to see what is happening. Show Explosions - Toggles explosion animations, useful to turn off during big assaults to see what is happening. Show Solyent - Toggles green area around collectors that makes energy. (default hotkey shift-O)Д¬N Info Panels- Toggles the energy and AC info panels. Opaque Creeper- Turning this option of will make the creeper more transparent which can be useful when there is so much creeper on the map that you can't see the ground underneath. Usually you want it on, but sometimes when you already neutralized the sources of digitalis it might be useful to turn off. Show D-growth - toggles on and off the viewing of the digitals growth area, it's the small white lines that show which paths can digitalis grow on. This can be important since you can sometimes have a hard time seeing what happens during an assault or mistakenly turn off the show creeper option(default hotkey shift-C) and wonder what's wrong with the game. The Visibility menu - allows you to toggle on and off different options that modify the information shown on screen.

I will proceed to explain what is where.ДЎ. Here you can see a screenshot of the game.
