How long does Class A have?

Hi Guys/Gals
 I have a Sugden A21SE which is a Pure Class A single ended design, I absolutely love this musical amplifier with its strangely plentiful 30wpc, it runs hots as they do, I always enjoy watching the faces of my uninitiated friends when they touch it after I mention they get hot, lol.
But in this modern green era I wonder just how long do Class A amplifiers have before Greta Thunberg gets wind of this inefficient method of creating sound and pisses on the parade?

Thoughts?

As my amps run on 230v I guess they draw 1/2 the current and 1/2 the power?

The current is halved, but the voltage is doubled since :

Power = Current x Voltage

and it is a wash.  You'll get a lower voltage drop though, since

V = Current x R

therefore the voltage at your outlet will sag less for the same power.

“There is a cult of ignorance in the United States, and there has always been. The strain of anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that my ignorance is just as good as your knowledge” Isaac Asimov

The young girl is merely an advocate for her generation. Good thing they have those based on some of the things read here. Narcissism enabled  is the next big epidemic we will find ourselves having to address on a large scale.

Yes comrade. We should deny people who disagree with us their first amendment rights so that the only opinion that is heard is ours.
