Using all available energy in early rcl

[Aerics84]

What is the current inefficiency the bot is engaging in? If the main room has a lot of remote rooms the room will be full of creeps with energy, but mostly no builders or upgrades to using it. At the both sources lying a few thousand energy on the floor no one pickup and using it. https://screeps.com/a/#!/history/shard2/E53N42?t=43664900

What should the bot be doing instead? Spawn more builders and upgraders based on the energy is available in the room. Not only based on the 3 containers. Look at the (remote)haulers, too. Priority first the energy lying at the sources inside the main room and if they are not enough push more outside to remote rooms.
