== Coal v Solar: The debate ==
There is also [[Coal power plant| another]] facility that creates energy! Coal power plants also exist, and there can be issues with on picking which one you might want if you are a newbie. The question is: Which one do you pick? On one hand, you have the coal mine requirement for a coal power plant but it gets 45x more energy every 90s. On the other hand, solar has no inputs but it has less output than that of a coal power plant.
Coal power plants are is better if you have a supplier of coalOR if you have the coal detector uu, as it's more efficient. However, not everyone can just buy coal from the live market (Shortage of resources becomes a factor.) , nor have uu tech, so solar is the best option for full idle, "I have no market connections" , I don't have uu type of people. uu tech used to make coal better than Solar in terms of grabbing coal detector uu but for a self-sustain build, coal detector uu is slightly worse than just pure solar farm. This may change if an update makes + assets also usable like regular items.
