AN INVENTION

In my opinion, one of the most important inventions in the history of humans is the electricity, concretely the lightbulb.

It is very important because at night, when we haven’t got light from the sun, we can work at home with light and we can play, read… We can also cook the food with electricity; we can use the oven, the microwave, the stoves… so we can always eat hot food and we don’t have to depend on the fire. In addition, in winter we could stay hot in a building without staying near the fire, so it’s not necessary to wear the anorak or the scarf indoor, and in summer we could stay warm when out it’s too hot. Without electricity, all electronic objects like mobile phones, television, computers… they would probably not exist.

For all these reasons and more, I think that the electricity and the lightbulb were and are a good invention because you can have light all twenty-four hours, without the sun.
