      and about 25% of that is fossil fuels.

      Sweden uses essentially no fossil fuels in the grid - it’s basically hydro, nuclear and wind for all of it. The small amount of fossil fuels used is stuff like burning plastics, and one oil plant that is turned on once in a blue moon when there’s an energy crisis. It’s national news when they turn that one on, and it’s considered a huge failure every time it happens.

      The real figure for fossil versus non-fossil energy in Sweden is 2% fossil versus 98% non-fossil, with hydro being the primary energy source (35-45%), followed by nuclear (30%) and then wind (20%). Source, in Swedish: https://www.energiforetagen.se/energifakta/elsystemet/produktion/

      A few errors

      • 130TWh is the final electricity consumption, not the generation. Since Sweden is a big net exporter of electricity, there is a big difference
      • I’m not sure what macrotrends refers to by “Fossil fuel consumption”, but it’s pobably referring to raw energy rather than electricity (which doesnt consider conversion efficiency)
      • In reality, sweden uses almost no fossil fuels in its electricity mix, and that is in large part due to nuclear
      • KWh and KW, not KW and KW/h
      • In your calculations you failed to account for capacity factors. Wind plants have average capacity factors of about 42% in sweden, so the capacity would need to be over double the consumption, even ignoring the variability of consumption and production

      Nevertheless, I do agree that Sweden doesn’t need more nuclear. It already generates some of the cleanest electricity in the world and I’d imagine fossil fuels are really only used for peak load.

          32500000000 KW/h per year

          That's 32500000000 kWh/y
          = 32500000000 * k * W * h / y
          = 32500000000 * k * W * h / (365 * 24 * h)
          = 32500000000 * k * W * h / 8760 / h
          = 32500000000 / 8760 * k * W * h / h
          = 3710046 * k * W * 1
          = 3710046 kW
          

          (You actually corrected yourself later when converting to mW.)

          A kW/h would imply that the power changes by that amount every hour, while a kWh is the amount of energy spent in an hour
