Long description
There's been a discussion recently how unrealistic is that gunturrets can do their rather complex behavior for a completely no cost in energy.
This mod adds requirement in energy for them.
Gun turrets draw about 6kW and if the power supply is disconnected for longer than 3 seconds, they stop working.
Other turrets that use ammo, draw 12kW.
If you wish you can exclude particular type of turret via config.lua.
The mod is written so as to not impact the performance. (The amount of calculations depends on the number of engaged turrets, not a total amount of them.)
