Responsible use

It is very important that each of us contributes to Brazil’s energy security by using energy rationally. It is vital to economize in order to achieve sustainable growth.


Santo Antônio Energia has collected some simple and practical suggestions which result in advantages for its use and the environment.


Rethinking habits.


Tips on Responsible Energy use(link PDF):





At home

Avoid using domestic appliances between 6.00 pm and 9.00 pm. This is called “peak time” in which electrical energy consumption is highest; public lighting is activated and lights are on in people’s homes. Consumption will be more balanced throughout the day if we all reduce our use of electricity at these times,.

Fridges are responsible for approximately 30% of a household’s total energy consumption. Remove all the ingredients from the fridge at once before cooking, to avoid opening and closing the door.

Keep fridges and freezers away from the stove, so that they do not need additional

energy to compensate for the elevated temperature nearby. Keep them at least 15 cm away from walls to avoid overheating. Never dry clothes and tennis shoes behind fridges. This increases energy consumption, as the clothes prevent the motor’s heat from dispersing and makes it run longer to cool the fridge.

Electric faucets use the same amount of energy as one of the leaders of electrical

consumption: the electric shower head. Avoid washing dishes with hot water.

Use your microwave intelligently. You can heat up two dishes at once when using an appropriate support.

Dishwashers use a lot of energy to heat the water used.  Always use the lowest possible temperatures (50-55o C, on the economical program). Do not leave a lot of leftovers on plates, as they will require a higher washing temperature. Use the right amount of soap or detergent, so that you do not need to re-rinse.

A washing machine represents between 2% and 5% of a household’s total consumption.

Wait to build up the maximum weight of clothes which is compatible with your machine before turning it on.

If you really need to use it at half capacity, select levels which use less water.


Use your dryer at maximum capacity when drying clothes and, of course, dry clothes naturally whenever possible.

Ironing is responsible for more than 5% of a household’s electricity bill.

Avoid ironing a small amount of clothes. A large part of the energy used to iron clothes is spent heating the iron, so wait to accumulate a reasonable quantity and iron them all at once.

Electric showerheads are responsible for approximately 25% of a household’s consumption.

Keep hot showers as short as possible.

  • • Leave the temperature dial on the “Summer” position on hot days (consumption is approximately 30% higher in the “winter” position).

Other domestic appliances:

  • • Vacuum cleaner (hoover): do not use it more than twice a week. It may not seem like it but a vacuum cleaner consumes more energy than the TV and computer. Always keep the filters clean.
  • • Hairdryer: it uses the same amount of energy as a washing machine. Only use it at maximum power when it is extremely necessary. Dry your hair in the sun on hot days – it is much healthier!

At the supermarket

  • • Use a reusable bag for your shopping. Disposable plastic bags are one of the environment’s major enemies, as not only do they release carbon dioxide and methane gases into the atmosphere during production but also pollute the soil and sea.
  • • Buy food which is produced in your region.  In addition to saving on fuel, you will support your community, neighborhood or city’s growth in this way.

Small actions can make a big difference

  • • Use your car less and public (buses and metros) and clean transport (bicycles or walking) more. You will stop emitting 700 kilos of pollutants per year by leaving your car at home twice a week.
  • • How about using the stairs if you are going up or down two floors? As well as getting some exercise, you also save the electricity used by elevators.
  • • Rechargeable batteries are more expensive but are much more profitable in medium and long term use. They last for years and can be recharged an average of a thousand times.
  • • Choose household appliances with low energy consumption: in Brazil,  look for appliances with the Procel (for national products) or Energy Star seal (for imported items).
  • • Use a ceiling fan. It is not always hot enough to turn on the air-conditioning. A ceiling fan is ideal to cool the environment in the majority of cases using 90% less energy. It is also a good idea to combine the use of both. Regulate your air-conditioning system and switch on a ceiling fan.
  • • Change your incandescent light bulbs for fluorescent ones. Lighting is responsible for approximately 20% of a household’s total consumption. Light bulbs with a higher wattage use more energy. Fluorescent bulbs use 60% less energy than incandescent ones. You will save 136 kilos of carbon dioxide gas per year in this way.
  • • Recycle both at work and at home. If your city or neighborhood does not have selective trash collection, take it to a collective post – find out where they are located in your city. Remember that recyclable material should be washed (in the case of plastic, glass and metal) and folded (paper).
  • • Use the telephone or internet at work and you will then save money and expenditure on any unnecessary journeys.
  • • Fly less and meet using video-conferences.
  • • Always turn off your computer when it will be out of use for more than 2 hours and the monitor for a maximum of 15 minutes.

• Turn off the air-conditioning in your office one hour before leaving. This is equivalent to a 12.5% daily saving in an 8 hour period, which is almost the same as a one month saving at the end of the year.
