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?

Imagine being so under-educated that you adopt the views of a 14 y/o child. 😜🤪

Imagine being so narrow minded that you are incapable of looking past myopic preconceived regressive attitudes about a messenger that you can’t hear the message.

But I’m sure you all have your PhD’s in climatology, which is why your opinion is more valid than their knowledge…

Yes yes, the new message is the world will end in 12 years.

Yeah, only those suffering from “myopic preconceived regressive attitudes” people won’t believe that 🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣

Better run out and go buy that bunker big guy. 😂🤣

Ps. I believe bunkers are going real cheap in Kabul.

Am I the only one to see a kind of cruel irony in @arcticdeth 's screen name?  "Arctic death" is in full denial while the ice cap melts away at an alarming rate.

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.
