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 long as the speaker I want needs/wants a lot of juice (Magnepan at present), I’ll likely use a Class D power amp, likely preceded by a tube or Class A front end. But I am one of those who also finds Class A has a certain appeal with high-efficiency speakers, and so I will have my First Watt/Pass (diy) amps in secondary setups. I’m on all-wind power, so I don’t feel guilty leaving it on. But I’d still feel pretty silly running a 100-watt or similar size Class A amp.
