Solar energy is the energy obtained through the light and heat emitted by the Sun. It can be used in photovoltaic or thermal form, generating electric and thermal energy, respectively. Considered a clean energy source, solar energy is one of the most promising alternative sources to obtain energy. But how does solar en...

Renewable energy, also called alternative energy or clean energy, is that energy obtained through sources that do not generate great negative environmental impacts. Among them are solar energy, obtained through sunlight, and wind energy, which comes from the air and the winds. In our business, we give priority to the resources provided by rene...

Also known as wind power, wind energy is present in the masses of air and wind that can be harnessed and used to generate electricity. The process for harnessing wind energy depends on wind turbines or windmills, equipment responsible for, upon contact with wind, rotate and generate other forms of energy, such as ...

The fuel cell is an electrochemical device that converts the chemical energy contained from hydrogen into electrical energy and water. Today, unfortunately fossil fuels have impurities, many of them composed of sulfur, and the high temperatures reached in the combustion process involve a reaction of nitrogen present in the ...

Biomass is all organic matter, of vegetable or animal origin, that can be used in energy production. It is obtained through the decomposition of a variety of renewable resources, such as plants, wood, agricultural waste, food waste, excrement and even garbage. In the electricity sector, it becomes a promising alternative, highli...

Is it necessary to unplug everything during thunderstorms? Does drying clothes behind the refrigerator increase consumption? Surely you have heard these and other questions when it comes to electricity. There are so many myths that arise when the subject is electricity consumption, that we do not know what is true or false. Learn more here wha...

To use electrical energy consciously and safely, it is important to pay attention to some safety tips and practices: Do not fly kites near the electrical grid. Contact with the power wires can be fatal, in addition to the danger of falling due to the impact caused by electric shock; Do not use “Cerol”. This cutting mixture, made with glue,...

Some accidents can be avoided if we take certain precautions in our daily lives, especially when approaching power plants. Do not swim near the dams or approach areas considered to be at risk, they are just some prevention and tips for a safer day-to-day. Below, we separate some more important aspects, which are worth the alert. Power Plants D...

We know how important it is to have safety in all areas of our lives. In buildings it wouldn’t be any different either. Remember our safety tips whenever you start a new project and protect yourself! Before building, contact Cemig for further guidance; Scaffolding and walls near the grid represent a danger of electric shock; Do not come n...

At home, we use several appliances connected to the grid. It is very important to observe some precautions, to use electrical energy in a conscious and healthy way. Check out some of our tips below: Do not use household appliances with wet hands or feet or in places with water and humidity. Wet skin facilitates the passage of electric current ...

Lightning strikes directly into the electrical grid or its vicinity, especially in open and high places, causing an increase in voltage. This overvoltage propagates in the grid until there is a point with passage to the ground. For the protection of buildings, it is necessary the use of lightning rods in compliance with ABNT NBR 5419...

Have you ever seen a weather radar? It allows you to identify, through the emission and reception of waves, the formation of rain, storms and hail. Our radar is installed in the municipality of Mateus Leme at “Morro do Elefante”, Minas Gerais. Its strategic location, at about 1,270 meters of altitude and almost without barriers in its...
