  • Fwiw, not to diminish this feat but rather as context: A significant part of the (calculated) wins in the early/mid 2010s came from moving from coal to fossil gas. Unfortunately, fossil gas tends to be much more polluting than (usually) assumed, because of flaring and pipeline losses. Thus some of earlier CO2e wins may be due to number fiddling rather than real reductions.

    However, recent years do show massive wind power growth and that’s fantastic.

    Side note 2: The UK has a lot of work ahead on electrifying heating and installing heat pumps.











  • Afaik, German reactors were designed to be throttled to 60% capacity, within around a week. And doing that too often wasn’t safe either. And there was no economic incentive to do so because a reactor throttled is not a reactor earning—although you have to do a bunch of extra work to throttle the reactor and you’re only conserving negligible amounts of fuel.

    I am not deep enough in the topic to know whether that’s a limitation due to all the German reactors being particularly outdated. But “30 min” and “20%” sounds more like an emergency protocol to me rather than any kind of srandard procedure.








  • And yet, China is still building out solar, wind, and coal faster.

    That’s despite nuclear having a lot of advantages in China:

    • high level of centralization (even SMRs produce 0.5TW)
    • high level of governmental involvement in economy (which means huge investments can be a lot easier)
    • low level of governmental transparency (which means you don’t have to deal with NGOs or Nimbys)
    • rapidly increasing demand for electricity (which creates an incentive to build as much supply as possible)
    • first-class universities (for independent R&D)
    • large land mass (which is useful both for mining and disposal)
    • lax environmental policy (same)
