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?

sad reality about frailty of the human condition

I love my luxman... They do ab amps as well... My 550ax2 is amazing for my tannoys... I was debating getting the sugden IA4 as well but got a great deal with luxman so went for that... Either would make me. Happy

@perkri I’ll glad take that VFET off your hands if you don’t build it!

@sgreg I’m a hypocrite and use class A amps, but… are you denying climate change? LOL
