Gene:
In your apparent desire to use the dollar sign as if it were an SI unit
symbol (which is clearly is not), you have created a redundancy.
Basically, it has to be "energy per dollar ... ... is 440 MJ" or "the value
of energy ... ... is 440 MJ per dollar."
I wouldn't mention it, but I know you, yourself, are a stickler for correct
forms.
