How would our lives change if we could no longer get electricity supply?

Dear Student,
                           In this electrified era without electricity almost   nothing will be possible 
                           first thing which is most important light would not be there in night .
                          Most of electric based factory will be closed .
                          No fan , no cooler , no TV , in our life most of usable energy comes from electricity 
                           without it it will be very tough to send energy from one place to another etc.
