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 the same type similarly across wide geographic areas, so there

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 electricity generation. The end result will be that duri

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 often changes by as much as one third of Germany consumption

> 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 energy densities when considering weight, however when consid

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 it at meaningful density. Combine the last two problems toget

> 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 policy are not obvious, but this doesn't mean they don&#

> This is patently false. It's not false, it's just probably not easy to understand. It's easy to understand if we consider a hypothetical situation where the nuclear power plant is running AND Germany still keeps all othe

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 new possible fault regardless of whether it impacts th

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 subsidies will be required for additional renewable generati

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. The bulk electricity prices are already going down to

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 they will need to match energy supply and demand. Their con

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.

I think you should also consider tens of millions of people who lived under Russian boot in USSR itself and Warsaw pact countries. It appeared that wealth inequality is lower because there was no free press and thus no way to see it. People
