A new NASA study seems to pull the plug on space solar power, by saying its vastly more expensive than Earth based solar.

    I’m not debating that efficiency has improved.

    Total energy use by humans has increased and shows no sign of reversing. IDK what faffing around debating ancient CPUs is supposed to prove.

      They’re called examples

      Here’s the link from the other guy https://www.eia.gov/totalenergy/data/browser/index.php?tbl=T01.07#/?f=M&start=200001

      When the line goes Up ⬆️ that means usage is up ⬆️ when the line does down ⬇️usage is down ⬇️ if you look you’ll see after 2000 the line is trending down ⬇️

        That’s just for the US.

        Global energy use is still rising.

        https://ourworldindata.org/energy-production-consumption

        Things are getting more energy efficient and in his chart it shows per capita flat or trending down. But unless population growth is also flat than overall is still growing.

        That’s not to say energy use overall will never go down (it did during 2020 when everything shut down) but it hasn’t yet.

        Edit: words are hard.
