Is there a legitimate reason for everybody and his brother being part of `enty`?
enty used to be "energy type" and encompass primary, secondary, and final energy (
fety). Now it includes useful energy, a gazillion emissions,
peog as an oil-and gas aggregate, as well as the
perm tradable assets.
Is there a legitimate case where they all have to be in the same set? Because that's blowing up all the variables and parameters involved and is quite confusing from time to time.
