That's a great point, of course. More technology typically requires more energy, which doesn't just appear out of nowhere. Although newer technology tends to require less energy per unit of work/computation, in aggregate the amount of technology in use increases rapidly enough that net energy requrements increase as well. I'm hopeful that solar power will play an increasing role. Our sun won't last forever, but barring catastrophe it'll be there on any timescale those of us living now care about. Of course, solar's effectiveness depends on how much the energy captured by solar panels exceeds the amount of energy requred to manufacture them. I get that sense that solar power's efficiency and cost effectiveness continue to improve rapidly, but most of my information on the topic comes from mass media. It's an area I'd like to know more about, but I don't currently have enough time to do the research needed to properly understand it in depth.
