Whoa this looks like it could be a game.

Is there a game like this??

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.

It's called Factorio.

I developed one around two years ago, you can try it out at https://electrobillion.evrim.zone/

It's a fictionalised version of the grid, but teaches some of the basics well!

CircuitJs, but you have to draw your own grid first.
