Changing the past

So, my task now is to change the past:) It is hard to choose one specific event and I have decided to choose one invention that I would erase from the history.
Have you ever imagined how we would live without an electrical current? We do not pay attention to such things, because it is obvious for us that they exist. But let's think for a while how it would change our lives.
And it is not only about the light:) Almost every machine that we use at home needs the electric current in order to work. If we did not have the electricity we would have to do everything using only our own strength. It sounds rather terrifying, doesn't it?
I suppose that we would come back to other sources of light, like candles or paraffin lamps. We couldn't even go out at night because we would not see anything! Also the traffic at night would be stopped as the drivers did not see one another or the traffic did not exist at all due to the fact that a human cannot create a car without the use of special machines....
Although it seems impossible we would have to live without such facilities like fridge, lift, car, but maybe we would invent something different. I hope that Doctor Who would come and save us:)
