World now has five times more PV than nuclear power
www.pv-magazine.com
Authors of the World Nuclear Industry Status Report 2024 the world had 408 operational reactors producing 367 GW in the middle of the year, which is significantly less than installed capacity predictions for solar by the end of the year and five time less the world's cumulative PV capacity, which is now approaching 2 TW.

“But even in the only country that is massively building, China, nuclear development is comparatively marginal. In 2023, China started up one new nuclear reactor, that is plus 1 GW, and more than 200 GW of solar alone. Solar generated 40% more power than nuclear and all non-hydro renewables—mainly wind, solar, and biomass—generated four times as much as nuclear.”
The report also highlights how nuclear power is being challenged not only by the strong growth of solar and wind, but also by battery storage, whose costs are projected to decline below those of coal-fired and nuclear power plants by around 2025 in China. “Solar plus storage is already significantly lower than nuclear power in most markets today, as well as highly competitive with other low-emissions sources of electricity that are commercially available today,” it also notes.
The authors also cite data from investment bank Lazard revealing that solar-plus-storage can already be cheaper than gas peaking and new nuclear. “The competitive cost and large-scale availability of variable renewable energy sources combined with firming options—especially storage—could well turn out to be the game-changer of energy policy in the years to come,” they further explain.

    Five times more PVs at a 20% capacity factor means it evens out.

    The vast majority of those PV installations were in the last 7 years or so. We also built more manufacturing capability during that time. Meaning PV installations are being rolled out on an exponential curve, not a linear one.

      It’s not an exponential curve. It’s slower than that.

      It’s more than linear; we are adding more capacity each year than the year before. But added capacity per year as a percentage of the previous years total is a decreasing.

      If it was exponential the growth would be a straight(ish) line when plotted on a logarithmic scale… it’s not. On a log scale the line inflects.

        It’s exponential.

        To call solar power’s rise exponential is not hyperbole, but a statement of fact. Installed solar capacity doubles roughly every three years, and so grows ten-fold each decade. Such sustained growth is seldom seen in anything that matters. That makes it hard for people to get their heads round what is going on. When it was a tenth of its current size ten years ago, solar power was still seen as marginal even by experts who knew how fast it had grown. The next ten-fold increase will be equivalent to multiplying the world’s entire fleet of nuclear reactors by eight in less than the time it typically takes to build just a single one of them.

          Whoever wrote that article is playing fast and loose with the definition of exponential.

          Here’s the actual data of global electricity source on a log scale for the past ~15 years

          Notice that the line for both wind and solar is inflecting to the right. If it was exponential it would be straight.

          The time between each doubling of output is increasing.

          It’s close, but not enough to be exponential growth.

          It was exponential for a while but it’s slowing down in the last decade or two.
