I've been working on adding energy mechanics to Microlandia. right now i have added solar, wind, nuclear and coal power and houses, datacenters, factories etc use real-world usage. there is power selling and power buying and a score for carbon footprint. There's still a lot I want to do and I will add it gradually, like: rooftop solar panels, different regions with different sun/wind resources, grid and station failures, and still finishing the fact checking of energy usage for all the buildings.
