Now I don't know where is the power coming from, whether it is still powered by coal or another source. But the price move is an indication that the it's not coal anymore or it's soon to stop being.

I live in germany and I pay 0.23 for electric power.

Germany has been trying hard for decades to go cleaner/greener... we have loads of solar and wind turbines (subsidized), some hydro. We also have a fair share of nuclear. These sources have specific problems: solar and wind is unreliable and costly, nuclear can't be regulated well and has a major waste problem that doesn't simply go away by waiting a couple of generations. Therefore we still have lots of plants that simply burn fossil fuels (like coal or natural gas). That delivers plenty of energy and the output can be regulated in minutes. Just making the point that your energy probably not coming from some single source, but is mixed via a vast network from all kinds of sources.

Also, about the coal: have you every played command & conquer? Usually it's a good strategy in early to mid game to start collecting the spice as far as possible from your base as soon as you can (without slowing your building processes too much and while players are still busy building weaponry and the basis for production so that your harvesters can usually defend themselves sufficiently) and keep the stuff close to your base for later in the game when shit hits the fan and you can't have unprotected harvesters wandering around the map far from home, taking too long to supply for the increased funding demands and getting killed due to lack of protection.
