I read this book in 1993 or thereabouts but could have been decades old for all I know. It was in Greek but was definitely translated from another language (I have no idea which one).
What I remember from the story was that something happened and everything that used electricity stopped working. This might have been caused by aliens, but I don't remember aliens actually appearing.
I remember a particular part where someone had two cigarette lighters, one using fuel and one electric, and only the former worked.
I think people learned to live happily after getting over the event and in the end, when someone re-discovered electricity, the others destroyed his machine, saying that life was better without electricity.
This may have been a book for children, but I'm not sure.
I'm not interested in reading it again, I just remembered it and am curious about whether the author was a Luddite.
