Let's beat this with actual statistics, I think it's pretty obvious this person doesn't really understand anything about what she is talking about anyway.

Going off a graphic, it seems in 2018 the world used 200,000 (TWH), and following the usually % increase in electricity cost, it's fair to say that ~ 84.23 TWH has been used in 2019. Now, I am using a tool created by students at Cambridge university - https://www.cbeci.org/.

With the current bitcoin network power (which keep in mind, is even higher then the network power last year), it estimates that 10-11 GW is being used a year for bitcoin network power. 0.042‬% of electricity... That is not a much, compared to how much % other services take up.
