Why electricity saving?

The demand for electricity is showing no sign of subsiding. Rather it seems to be increasing everyday. But the fossil fuels and other sources are coming to a slow end. So what happens then? There will be no source from which electricity can be produced. Thus we need two things, one is to learn how to save electricity, and the other is to start using energy saving devices. Although most of these devices are fake, some of them put a good job of saving electricity. Thus these should be identified and used more. Also a change of habit is needed - a behavioral change to make people feel good about themselves for saving electricity; but this change is not impossible.
