Modern life can not be imagined without electricity. Modern life can not be imagined without electricity. Thus, most of the discoveries of the last century would not Thus, most of the discoveries of the last century would not have been made if it were not for electricity. It is used have been made if it were not for electricity. It is used everywhere. Assuming that, suddenly, we were short of everywhere. Assuming that, suddenly, we were short of energy, this is what would happen: energy, this is what would happen:
