What would happen if electricity were cut off starting tomorrow?

Hello, I am new to this world and thought I would first ask those who know more than me.

Based on your experiences, if starting tomorrow, in an average house with unprepared people, the electricity was cut off, what would happen? I have read in other posts that the first problem is frozen and refrigerated food and then chargin phones, but then? Edit: I’m not searching for solutions, just for scenarios and eventual problems to overcome.
