you mean the puny Swiss designed car in existence, the Smart Fortwo.

, where do you think the Swiss drive their cars, on the slope of Alps? Swiss use their congested commuter trains and buses as well as 2 legs to travel around and maybe use their cars during vacation outside the country. The Swiss energy footprint for all practical purpose is nada, and thus Bitcoin network's energy consumption, which is similar to this tiny country, should not be a point of debate.
The moment you bring in gas consumption per car into a discussion about electric energy consumption is the moment you lose all credibility.
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.
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.
This is the problem, actual data!
It's like taking road fatality statistics from 1860 and projecting the situation in 2050 based on that.
80Twh might still be nothing but look at the exact graph you have posted:
July 2015, estimated at 2Twh
July 2017, it was estimated at 10Twh.
July 2019, It was estimated at 60 Twh.
Right now it matters not that much but what will happen if the price grows again?
If we see 800 Twh?
Oh but it will still be only 0.4% of the world global consumption
What happens when bitcoins will go beyond the 100k?
I'm going to tell you what happens, consequences! and what happened in Plattsburgh will happen all over the place!
But it's not a problem, right, miners will go to a country where they accept bitcoin mining, of course, this will be with consequences just like every damn action on this planet has. You want all the mining gear to end up in a country like Russia where they could simply cut the entire network and seize the machine because Putin had a bad dream?
Right now on a global scale bitcoin mining means nothing. But so does bitcoin, what's that 300k transaction day and 20 million addresses with more than 1$?
It's like the economy of Swaziland (not Switzerland).
And when it will really start growing and start being used its value will grow, consequence > reward growing > consequence > more mining gear > consequence >electric consumption.
But yeah, all it's fine now, let's just wait for it.
Just like all was fine till the fork wars and the fee war at the end of 2017!
Everything is fine ....till .....it is not fine anymore.
And again I'm not advocating for PoS which is really a Piece of S, or master nodes or else. Nor do I think that changing algorithms will fix it since it's pretty obvious for anyone knowing what revenue and cost are it won't.
