I absolutely agree that it wasn't clear. I don't think wattage per clock cycle is a meaningful measure here - after all, all languages will have the same wattage per clock cycle, if they're executing the same instructions.
What's important is wattage per unit of useful end product, in my example pricing an option. For others, it might be wattage per web page served or anything else.
