I ran out of power before I ran out of Labor. Admittedly I wasn't pumping every automated Dump/Market, but I really didn't need to because I was choked off at each step of the recycling tree getting more labor than power.
That's kind of how it's meant to feel there. Generators are capped on purpose, so power is the thing you have to work for mid game. The Grid Foundry is the way out: batteries and steel from the recycling tree turn into permanent power. In the full game that part is a lot more balanced, there are more ways to make power, so it doesn't choke you like this. Thanks for the detailed write-up tho.
