Saving energy in your daily tasks

There are a number of little tricks and tips you can use to save energy every day. Here are some tips for actively reducing your own energy consumption.


  • Approximately half of the energy consumption in your home is caused by heating.
  • Keep your room temperature between 20 and 22 degrees – lowering it by one degree saves 5% in heating costs.  If you are away for a longer time, you can set the heating to a lower level.
  • If the apartment feels cool, you should first add some clothing instead of setting the thermostat any higher.
  • Make sure there isn't anything large, such a couch,  right in front of the radiator, as this would stop the heat from radiating into the apartment. 
  •  Check regularly that the insulation materials around your doors and windows are in good shape.


  • Turn off lights you don't need. Modern lights do not wear out from being turned on and off frequently.
  • Use energy saving bulbs.  On the average, they last ten times longer than normal bulbs. Remember that energy saving bulbs are problem waste and must not be thrown in with mixed waste.

Electronic devices 

  •  Standby mode uses electricity, so turn your devices off at the main on/off switch if you are not using them.
  • A charger left plugged in uses electricity even when it isn't used.
  • Laptop computers use less electricity than desktop computers.

Refrigerator and freezer

  • A freezer with a layer of ice can use twice as much electricity as a properly defrosted one. Please defrost the freezer regularly. 
  • The freezer works most efficiently when it is 2/3 full, while the refrigerator should optimally be 3/4 full.
  • Do not put hot food in the refrigerator or freezer.
  • Do not set the refrigerator or freezer to an unnecessarily low temperature.


  • Only run the washing machine when you have a full load, and use a low temperature. Up to 90–95% of the washing machine's energy consumption results from heating the water.
  • A fast cycle may save water, energy and your time.
  • Dry your washing on a line, not in a dryer, if possible. Plumbing fixtures
  • Notify us of leaking taps and toilets as soon as possible.
  • Only run the tap when you need water, don't run it unnecessarily.
  • A shower uses less water than a bath in a tub.
  • Do not put food scraps, tampons, sanitary pads, cigarette butts, cotton buds, or any other similar items in the toilet, as they cause blockages in the drains and burden the sewage treatment plant unnecessarily.

Food and cooking

  • Favour less processed and locally produced products.
  • Select recyclable packaging.
  • When you cook, use a flat-bottomed pot that fits the size of the ring. Use a lid and an appropriate amount of water for boiling.
  • Frying and cooking on the stove uses more energy than baking in the oven.
  • When you defrost food, a microwave oven is a more ecological option compared to the oven or the stove.
  • Don't forget to make use of the after-heat.
