> That doesn't change the fact that first and cleaner renewable energy source is consumption reduction.

1) That's not a fact

2) That sentence doesn't make any sense grammatically

3) Consumption reduction = lower quality of life & health for poor people (the rich have 0 interest in consumption reduction... do you see the davos crowd turning in their private jets?)

Having a house with better insulation reduced my mother energy costs from 6k to 2k, with 2022 being a year where the electricity was more expensive.

She does not have weirdly distributed heat islands in her house, and supported this winter way better than past years.

She reduced her consumption by 3, increasing her quality of life.

I'm sorry, still trying to learn a foreing language, thank for your caring advice.

"Consumption reduction = lower quality of life "

That's false, see LED lights.

Efficiency has it's limits and many industrial processes are already pretty close.

Of course there are limits, but new processes can be invented, it's just history. Electric cars are much more efficient than ICE ones. First civilian jet engine designs could be efficient up to a point, then they changed designs. Laser uranium enrichment is so much more efficient that USA classified it [1]. Transformers training is more efficient. And so on...

Assuming "cleaner" means more sustainable for the environment (not only carbon footprint, but considering biodiversity), then I think it's pretty much a fact: we are living a mass extinction right now, and that's really correlated to our energy consumption.

If it's purely about carbon footprint ("let's finish killing the biodiversity and make living on Earth as close as possible to what it would be to live on Mars"), then it's still debatable whether or not we could keep increasing consumption with the end of fossil fuels (and that's coming).
