    Nextcloud is great. However, at least in my case selfhosted version is rather slow even with enough hardware and recommended tuning.

    The amount of annual subsidies is around $2 billion. It's a tiny number for a country as large as Japan. Their GDB is $4 trillion per year.

    5PJ is not that large, only 1.4 TWh.

    Low electricity costs are a problem for all electricity plans, not only nuclear. Renewables are even more susceptible to this because the weather affects all renewable plants of th…

    Wind and solar are only possible because they use the rest of the grid as effectively a giant battery. When the sun shines and/or the wind blows, someone else needs to reduce the e…

    Also, the reason this is only possible at all is that Germany uses the rest of Europe as a giant battery to manage the non-dispatchability of renewables. The import-export balance …

    > hydrogen fuel cells are technically batteries and have absurdly high energy densities. The devil is in the details - this is only partially right. Hydrogen has absurdly high ener…

    Fuel cells is not a problem. Hydrogen storage is. Hydrogen is just a very nasty material, it leaks through everything, makes steel brittle and requires extreme pressures to store i…

    > What utter bullshit. Most countries could do so. Unfortunately when wishes and hard reality meets for a fight, the reality wins. In this case failure modes of renewable-only poli…

    It's not even that all the nuclear power plants failed. It was a combination of a choice to defer maintenance due to Covid, and also a choice to stop every power plant to address a…

    Renewables won't power everything, bulk electricity prices are already becoming zero across Germany when the weather for renewables is good. Once this is widespread, further subsid…

    The obvious downside of this decision is that nuclear generation that has been shut down is replaced by coal and gas. Also it's not a given that the renewable strategy will succeed…

    There are many different consensuses. In this case the most important consensus is what is the opinion shared by the operators of electricity grids and the like, because ultimately…

    This would still cause hydrogen embrittlement which results in cracked steel pipes.

    There are also 2 EPR designs producing electricity in China since 2019, so your sources aren't correct.

    Hinkley point construction started 2017, not 2008. In 2008 even the site wasn't picked yet.
