if there is no eletricity in the world

I arrived the laboratory as usual yesterday morning and turn on the computer. I was wandering that what i can do today. I went to the internet. Suddenly the computer's screen was dark and lamps were dark too. The eletricity power was off. The whole building lost eletricity power. Suddenly it was very quiet in the room, there was no noise from the computer. Firstly i did not know what i can do without the computer. A few minutes later i realized that i feeled good without the computer and eletricity.
Mordern people have used to the mordern equipment such as computer, if there is no eletricity in the world what we can do or how are our life?

The first

s not my first blog, because i worte several blogs, and i do't insist on for a long time. But this is my first english blog, i hope that i can insist.
Maybe there are many errors in my blog, whatever. I insist on writting, this is the most important.
But there is another problem what i should write. I can write what had happened in the whole day or the movies i had watched.
That is all.
