I don't think a single metabolism system emerged
to start life. I think the entire planet had sun
energy forced on it. And it is this forced collective
energy that was the initial metabolism/energy that led
to the Darwinian replicator and our modern day
chemical energy system which all came later.

Thus energy was forced on all the earth - and it
was this energy that led to the more complex
chemical energy systems of life.

It was not the other way around. Here are two
scenarios that I've seen suggested - that don't make
sense to me.
1.  a fluke event
starts a single entity that is born with 
the already highly evolved
ability to use chemical energy.

2. a single
replicator emerges. Then over time 
it  evolves a specific and independent 
metabolism system. Yet  in a catch 22 all
through this evolving phase to get to
a metabolism system, it  must have energy -
and how can it get energy when its metabolism
system is not yet evolved?
It's like using a lightbulb to see better while
your inventing the first lightbulb!
