If we’re talking “world,” global coal usage is predicted to increase, much of it in China and India, before declining later. Apparently with electricity usage going up, there’s more of every kind of power generation? https://tildes.net/~enviro/1jqy/coal_is_powering_the_energy_transition https://tildes.net/~enviro/1jqy/coal_is_powering_the_energy_... Also, cheap solar seems to be running into something like Amdahl’s law, where the solar panel cost is a small part of total cost. Hard to say what the trend will be for non-panel costs. How cheaply can they be installed and maintained?

Panel cost? The floor is the limit. [1] Installation cost? Depends on local labor wages but the skill is easy to learn. I'd recommend to DIY a couple 500 Wh panels just as an experiment. [1]: https://ourworldindata.org/grapher/solar-pv-prices https://ourworldindata.org/grapher/solar-pv-prices

  That site is kinda bad. They show the same number for '21/'22 and don't have any data for '23/'24

    Yeah i'd be nice to have the other two datapoints. Production cost per PV watt was around 15 cents at the end of 2023 [1]. Some claim that by the end of 2024 this figure will reach 10 cents per watt.
