Your graphic is garish and oversized, in my opinion.
As for the "article", its the classic "why are we wasting power to run the Bitcoin network, and OMG, if Bitcoin takes off it will require more power" strawman.
There, saved you about five minutes.
LOL. I like the summary though. This indeed saved me five minutes if I just read your comment.
In my opinion, bitcoin is really wasteful as paper money. Paper money uses trees while bitcoins use up a lot of power and produces carbon footprint because of the energy it uses. So I think bitcoin will power the future too, as we would turn to green energy by the time bitcoin uses so much energy.
