Very good points. Just note that nearly all these arguments work even without the global/international dimension. Think of power grids, a smartphone, life-saving health technologies, all infrastructure that makes life in any small.or large city possible. No US state can survive without experts.

Do you know simple answers that can realistically work for >8bn people without need for complex systems?

I candidly ask, because I don't know the answer: are the 4.7 €bn announced by the Commission fresh (additionally, previously not planned for SA) money, and how does the fresh EU money compare with USmoney planned for JETP and any other formerly US-funded energy transition projects in SA?

Key argument, thanks! What impact of on investor's confidence about US debt? If I am not wrong, the US treasury must sell a couple of USD trillion newly issued securities every month .. Of course the Fed can print money to pay for the (few) contracts still valid => more inflation upcoming?

=> €59bn avoided fossil fuel import costs due to new wind & solar in the EU since 2019.
=> 213 gCO2/kWh in EU power kix, 26% less than 2019.
=> Huge growth of wind & solar ahead.
=>Business model for power storage and demand response improving.

Not sure there is much joy in that, except it proves the inherent limits in the cross-border collaboration btw extreme nationalists. Mr Vistisen is from an extreme right wing party, allied with the likes of Le Pen, Salvini and Austria's FPÖ.
