What is electricity?

World energy consumption is undergoing an electrification process, supported by the digital technological transition of recent years. At the same time, there was the development of a renewable energy industry, whose competitiveness with fossil energies has been increasing, supported not only by cost reduction, but also by public policies to meet environmental goals.

What is electricity?

Electricity is the set of physical phenomena associated with the presence and flow of electrical charge, which include, among others, lightning, static electricity and electric currents.

Electrical energy results from the existence of negative electrical charges (electrons) that, when in contact with an electrical conductor, form an electrical current due to the potential difference between their ends.

Electricity can be produced using different energy sources:

  • Renewable source:Solar, wind, hydraulic and geothermal;
  • Fossil fuels:Coal, oil or gas.
