I like wind turbines - in Chile!  1)  ;-)

Some provoking technical questions, I'm worried about:

1. Six Questions about getting power from wind and sun (in German)https://www.yumpu.com/de/document/view/62058328/6-fragen-zur-stromerzeugung-aus-wind-und-sonne-2018-09-09 

and possible answers:  https://www.yumpu.com/en/document/view/62108811/power-statistics-and-h2-evolution (in English), 

2. For more than 100 years we are accepting to burn 250% to 300% chemical energy of coal to get 100% electric energy - with hydrogen this is not better - but not either worse ...

see also: https://www.siemens-energy.com/global/en/offerings/renewable-energy/hydrogen-solutions/haru-oni.htm - replacing 20% of German's gasoline consumption per year by e-fuels will need only 10 plants like Haru-Oni in its final production state as announced for 2026

=> let's solve economics!

... Der strategische Ansatz für Siemens Energy ist die sogenannte Sektorenkopplung. Die Energieindustrie, die chemische, die Schwerindustrie und die Transportindustrie ließen sich durch Power-to-X zusammenführen. „Die Sektorenkopplung und Power-to-X sind der Weg hin zu geschlossenen CO2-Kreisläufen und CO2-neutralen Infrastrukturen“, heißt es in einer Broschüre von Siemens Energy.
