Mmmm no. For one thing this article is ignoring how much electricity “mining” takes. Plus the general internet electricity which bitcoin can’t function without. There’s no way it uses less electric than the other forms of digital money (debit cards, EFT, etc). So at best it’s a net zero.
I think the point is simply that since bitcoin mining takes energy, the search is on to pursue lower cost electricity. It obviously takes energy, like many other industries.

Not sure. There is a whole infrastructure to support the fiat money system - Fed, Reserve banks, banking, etc.
Mining is a euphemism for the expending of energy to secure the ledger described in the post. The term comes from the reward for the work in the form of bitcoin.
