Unscientific, sensationalist, and pretty much wrong.

It’s just not a great argument, and doesn't consider the opposition argument - the human rights benefits (for people fleeing war zones, in predatory monetary regimes, etc.) are worth the electricity usage – because people/the market are valuing it that way.
