Energy is converted from oil by power generators. Each generator can convert oil from 4 derricks, that are scattered on the map. Derricks are automatically assigned to power generators.
A power module can be build on a power generator. It will increase it's power production by 50% but will overcharge and damage it over time. Once build, a full unit of production should be near the generator to prevent the explosion.
Building structures, producing units or researching costs energy. The full amount of energy must be spend before the production or research starts.
When first assigning a production, the energy is spend. When not enough energy is available, the progress bar is green and the number above indicates how many energy is missing. When multiple production are waiting, only one consumes energy and the other are queued, showing increasing energy amount.
Once the energy is consumed, the bar becomes yellow and the remaining time is shown above. At that point no more energy is required until the production finishes. The production time is proportional to the energy consumed.
The bottom bar indicades your stored energy. When it is positive, you have energy in storage that will be used for the next production or research. When it is negative, it indicates that at least one production or research is blocked and shows how much energy is required to start all of the current production and researches. Try to keep it rather low but always positive to produce things as smoothly as possible.
Unit of production
An unit of production is the ratio energy/time. With normal power mode, 2 derricks can sustain one unit of production. That is by the time the production is finished, it's cost in energy has been generated and the production could be repeated smoothly. Below is a table converting facilities to unit of productions.
|Generator with 2 derricks (normal energy mode)||1|
|Generator with 3 derricks (low energy mode)||1|
|Generator with 3 derricks (high energy mode)||2|
|Generator with module and 4 derricks (normal energy mode)||3|
