    They’ve had to keep upgrading them - the percentage of nuclear is the same, but no new plants have been built, so that extra power has come from research on how close to the red line they can actually run.

      New reactors just came online in Georgia this year. A $15 billion dollar planned project that cost $30 billion with overruns.

      So new or old, nuclear is really expensive electricity.

        A coal power plant is rougly the same cost per GW as solar or wind, doesn’t mean we should build more of them. I agree it’s expensive, but so were solar and wind a couple decades ago. Government investment helped research, development, scaling up - imagine if that had been done in the '80s, we wouldn’t be building natural gas plants right now.

          Incorrect.

          • Coal power $4,074 (3.07 x the cost of solar PV and 2.37x the cost of onshore wind)
          • Wind power (onshore) $1,718
          • Solar photovoltaic $1,327

          The first commercial nuclear power plant in the USA came online in 1958. source That’s 66 years ago. If time was going to make it cheaper we would have seen that by now. Instead the most recent reactors to come online, which occurred just this year, were projected to cost $14 billion and instead are cost $31 billion! Even worst, this isn’t an entirely new nuclear power plant, its just two additional reactors at an existing operational plant. source

          Nuclear just costs too much for what you get at the end.
