While entropy is related to energy flows, it is not a measure of energy.
The second law shows that if energy flows, there must be an overall increase
in entropy. If an ordered system is created, or if order in a system
increases, there must be a greater increase in the entropy of the
surroundings (i.e. the rest of the universe). It certainly does not inhibit
formation of ordered systems, only describes the cost of creating that
order.

That's a nice way to put it.
But I question one part. Forgive my weakness on thermodynamics. I'm more CS than EE.

If an ordered system is created, or if order in a system
increases, there must be a greater increase in the entropy of the
surroundings (i.e. the rest of the universe).

When you say "order" aren't you referring to energy?

And when order is increased, does the energy inside this piece
increase or decrease?

I am thinking of the "order" or rather - information - stored in a DNA
molecule.

Perhaps entropy and evolution aren't good disciplines to combine.
Randomness and chaos in individual DNA molecules is miniscule
comparted to the energy in the Universe.
