What is the use of electric energy?

In everyday life it is very clear what electricity is for, but we can evaluate the following examples:

Urban lighting: Electricity management has massified light and allowed our cities today to be more and better lit than before.

Car ignition: Operates based on fuel burning (petrol), but to initiate that controlled reaction requires a spark that produces the electrical energy contained in the accumulator (battery).

Our own body: The human body also works with specific and controlled doses of electricity. Among neurons, for example, there are electrical exchanges; muscles are operated on the basis of controlled discharges that activate elastic cells.

Defibrillators in hospitals: In hospitals, a device called a defibrillator is used, which by controlled electric shocks allows to try to start a stopped heart again.

Electrolysis: This laboratory chemical process involves adding electricity to various reactions or substances to separate them into their integrative components.

The many power plants: Whether hydroelectric, wind, geothermal or burning fossil fuels such as coal and natural gas.

With the advancement of technology there is a more palpable example of the use of electric energy in different areas and «curious» aspects, since it would be impossible for us to stay «online» if we could not charge our mobile devices, which today forms part of our lives
