What if there will be no electricity in world?

When you say "no electricity in the world" that would actually be near impossible. Your body organs such as your brain and heart generates flowing electrons and each cell of your body has a voltage potential. If you have seen lemons used to power a small digital clock you know chemical reactions can be used to generate small amounts of direct current. Moving a metal wire through a magnetic field generates a voltage. You can even generate electrical charge from applying mechanical force on certain types of material which is called the "piezoelectric effect". Even if you could get "no electricity" on Earth when the sun becomes very, very active during a solar storm electrical current can be induced in metal wires such as what happened to telegraph wires during the solar storm of 1859. There are so many possible sources for electricity both on Earth and from beyond Earth that having "no electricity" seems impossible.
