Electricity

Electricity is something that we use every day, and sometimes don’t realize how much we use it, or depend on it. There are two famous scientists who worked with electricity a lot – Thomas Edison, and Nicholas Tesla. Both of them made very big discoveries in electricity and science in general. We get electricity from power plants that send energy to other electricity centers that give it to our homes.
It is difficult to imagine life without electricity now. It is something that is necessary for everyday life for most people. We need it to work and to relax, to watch TV, to cook and so on. In the past people didn’t have electricity and I can’t even imagine how they lived. They use candles and oil lamps, stoves and so on. 
Nowadays it is even popular to go on special vacations to places that don’t have electricity. These places try to give people the experience of living like it was in the past. It also gives you the chance to find a connection with nature and have a better understanding of the world that we live in. For me, electricity is a necessity, I use it to play video games, watch television, and read using a lamp. However, I really enjoy going out to the countryside where we use fire for keeping warm and cook food. 
Thinking about all these makes us understand that we shouldn’t take everything for granted but be happy about what we have.
