See title.

Can you add a way to configure the electric energy usage? I'm looking through the config settings, and the closest I'm finding is multiplying drone performance multiplier and recipe cost (for a similar effect) but I'm not seeing something that directly modifies drone tier.

Drones electric power consumption was editable from the initial release of MD2R, you can find it on mod Map/Runtime settings page rather than Startup settings. It was technically possible to make this setting (as well as pollution rate) adjustable on the fly, without game restart, so I decided to do this. The factory must grow, the mod should be as flexible as possible :D Meanwhile, recipe cost and drones performance settings don't affect energy usage.
