Nano is now over 11 Million times more energy-efficient than Bitcoin?

I have been watching the daily updates from this site tracking Nano vs Bitcoin.
https://nanospeed.info/about

I know it fluctuates up and down day to day, but today it said:

Nano is: 9,740x faster. 11,331,000x more energy efficient. Infinitely cheaper to use.

What sticks out to me is 11 million x more energy-efficient than Bitcoin? I know Nano is good and energy-efficient, but this just seems insane. Is this true? How can anything else compete with this in the long-run? This seems like great marketing material. This kind of stuff should be highlighted more often. Is there any other comparisons that can be added to the site? If we could have live network comparisons to other cryptos as well it would be nice. Is there any other sites like this?
