Here's a good video on one method of calculating what the sum of the smaller individual parts would be. This is for the north east corridor but the same thinking applies to any rail project. It seems like about a million people live th

Why not? The great advantage of high speed rail is that with intermediate stops along the route you can service smaller cities which previously, or as you just did, would be considered flyover country. Thus making the value of the system gr

The question rather is, how much pumped storage do you even need when you do geographical decoupling through HVDC interconnections? Similarly, how bound are you to the local topology? The longest already existing HVDC line in China is 3,293

When talking about pumped hydro the roundtrip efficiency usually is around 70-80%. Not even close to batteries but way more scalable. Chemical storage is horrific. Creating diesel and burning it in a turbine or similar you start at 40-50% f

Honestly, not trading with Russia would have been short sighted. EU is founded on integrating the belligerents of WW2 close enough that it would be unthinkable to happen again. The same method, which at least has worked once, was tried with

Yes I know. The narrator is also wrong about the sulfur claim, similarly like the GP. I like it because it plainly lays out the issues with nuclear shipping, which then allows you to draw your own conclusions. It then ends on the same cool

Nuclear is an even more awful fit for land based use cases. The one saving grace it has for transportation is the energy density, not that it matters when renewables to green hydrogen, ammonia or any other solution paying some efficiency co

Because we want a solution before 2050.

So I presume you are for Poland to exit the EU also? I am not talking about relying on Russia here.

Batteries are already being applied on smaller passenger focused routes. It has become mundane enough to not even make headlines anymore. For example the ampere was ordered in 2011 https://en.m.wikipedia.org/wiki/MV_Amp

Always nuclear. It's like we're back in the atomic age of the 50s and forgot all the learnings since. Nuclear is horribly expensive and the entire maritime sector is a race to zero. Cheapest labor globally, cheapest material and s

Wind on the north sea? Or northern Baltic? Or Swedish or Norwegian hydro? Or alps based hydro? We are talking about a continent scale grid.

Much less than 25%. The nuclear industry in China is about the minimal investment while still keeping the door open, if some incredible breakthrough magically appears. https://www.iea.org/data-and-statistics/charts&#x2F

Poland is about the worst country in the EU for on-shore wind so a very cherrypicked counter example. Do you have numbers for off-shore parks along the Baltic coast? That would be much more interesting.

> That's why these things are nationalized and why uber isn't running our nuclear power plants for "hyper growth and exponential profit" Isn't it something to cherish then that renewables enables precisely that?

Not really. That is the dream of the fast reactor. It had been ongoing since the 50s. All attempts have been more costly than uranium reactors and there's only one in Russia which has operated with any kind of longevity. They also have

It would be kinder to view the French nuclear industry as a subsidy enabling a skilled workforce for the military side and their nuclear submarines, carriers and weapons. In that view it all makes sense, especially that the government still

We of course need to overbuild. You can do x4 for off shore wind and still come out ahead of nuclear. That map also corresponds to the time of year solar works 16 hours per day in Europe. It also shows that France Italy and the eastern part

So you need to cheat on the safety side of things to be a good model? Their once grandiose plan of being a nuclear power house exporting reactors stopped at exactly the 4 reactors to UAE which was signed before the scandal. Of course to an

Why does energy density matter? You can have wind farms on your arable land, about no loss at all. If you are crusading against land use a much better target is the beef industry. https://ourworldindata.org/grapher/land

Because renewables are handily greener with a fraction of the negative side effects nuclear brings. Both from taking care of spent fuel and safety measures. You can't even insure a nuclear power plant. That should tell you how safe the
