No, you've missed the point entirely

I don't think you fully understand just how efficient things have become.

An iMac G3 with it's 400MHz processor in 1998 consumed about 100 watts of power just running.

In comparison an iPhone 15 pro max with it's 3.7 GHz processor draws about 14 watts at maximum load and like <2 just idling

That's just the consumer end use electronics, power supplies themselves have gotten A SHIT TON better in the last 20 years. Through the 80s and 90s power supplies just were not efficient at all and a ton of power was... just lost...converting from AC to DC.

On top of that my statement of we use more things might not actually be even true, after I thought about it, we replaced a ton of gadgets from the early 2000s with a singular efficient power-sipping device. We don't carry MP3 players, CD players, PDAs, Digital Cameras etc any more nor do we really listen to a dedicated radio or stereo setup anymore (Audiophiles excluded).

So no, I agree with the other poster (who actually provided solid evidence, where's yours?) Total power usage is trending downwards thanks to efficiency advancements
