I agree with you about the lack of energy sources on the starting asteroid. But, I think this is intended to be a new challege, now they divided all the resources we once found in the asteroid between a half dozen of smaller asteroids that we need to explore and create "colonies" to bring those resources to the main base or even create various bases.
Now if you want to build large bases as we used to do, we will need to deal with some logistical problems to bring resources from other asteroids. As for example, there is a small asteroid full of crude oil that could feed a lot of petroleum or gas generator, but you would need to bring the petroleum.
The way the solar pannels are working now, you just don't need to care about searching for energy resources anymore. No more fun building crude oil boilers and condensers to get natrual gas hehehe.
