After the recent outages in Spain etc, which brought commerce to a standstill, I hear the EU has been crowing that if we had the CBDC this wouldn't be a problem, as it will work without electricity.
So this is the real reason for the power outage in Spain. 
This is a way to promote and impose CBDC. Okay, let's take off the tinfoil hat.
CBDC is a digital currency. And digital currencies can't work without electricity (Internet). Therefore, the EU rhetoric looks strange, or at least an attempt to promote CBDC on the wave of events that have happened. Maybe in the future, technologies will be created that allow using digital currencies without electricity, but at the moment this is impossible.
I have long wondered whether Bitcoin will likewise function without electricity - peer-to-peer by phone etc? And how about Blockstream satellite? My technical knowledge is limited on this subject.
These questions remain open, because the functionality of bitcoin is also tied to electricity (and the Internet). We will not consider experimental methods for now, because they have not yet been widely used and distributed. Of course, for complete decentralization, it would be nice if bitcoin had alternative ways of working (without the Internet). But I believe that the world will move in a different direction: in full coverage of the planet by the Internet (which is already happening in principle), than serious searches for alternative ways of confirming BTC-transactions will be conducted. The modern world is very dependent on electricity and the Internet and will not voluntarily refuse without apocalyptic reasons.
