An increasing proportion of renewables doesn’t necessarily mean a decrease in overall carbon output. Our per-person electricity consumption keeps rising. AI, electric cars, crypto, air conditioning to mitigate climate change, etc. all demand more electricity each year as they become more popular.
Wins don’t come from new growth being sustainable. We need to be actively shutting down the existing unsustainable energy production. It doesn’t matter whether this is done by replacing it with renewables, or by reducing our consumption with e.g. efficiency standards for AI and cars.
