I made the wind turbine to test it and meet the green requirement of life.
Wind turbines turn off when not enough wind is available, this makes sense. I play on the Island so no real info on what wind % and wiki states always on for the Island. However it turns off from time to time.
Solving this i connected to the same circuit a gas fumed generator with the Unpowered-auto-activation enabled. Thinking that it turns on when no when no green power is available. And so it did nice! NOT. After the shortage the generator continue to be on always on totally negating the wind turbine.
The only use I can find is for lights but not for kibble Refrigerators. Also it seams that I can connect unlimited devices to the same gas usage, not fully tested this since it is on Official server?
I didn't find the right solution from the Internet.
