You're criticising this article based on something it's not.

This isn't about units of energy measurement. It's about energy reporting at different stages of human energy-sector activity.

You might as well criticise Disney World for not being the Louvre, or a McDonalds restaurant for not being a library. That's simply not their goal, function, or purpose.

For those who report on energy utilisation, and those trying to understand those reports, the distinctions made here are highly useful and informative. The article should be assessed on that basis.

(I'm also aiming my criticism in part at those who've apparently up-voted the comment I'm responding to, who've compounded its author's error.)
