Mechanics of ambient temperature

In the cold season, when energy consumption quadruples both in the settlements and in greenhouses of the 3-4 levels, there is a need to optimize energy efficiency.
To reduce energy consumption in the settlements, it is proposed to build a heat exchange unit. At the initial stage, it can run on wood or coal, and the improvement of the technology will allow the use of steam as an energy source. The amount of wood, coal or steam consumption will depend on the needs of the population.
As for greenhouses of 3-4 levels, it is recommended to introduce a steam heating system to reduce their energy consumption.
Of course, this mechanic can also be disabled, just like ore sorting. It is optional and can be customized to suit the needs of the player or server administrator.
In addition, difficulty levels can be added for this mechanic. For example:
On easy level, energy consumption can be doubled (x2).
On the hard level, energy consumption can be increased sixfold (x6).
