It does not take much to save electricity, and on the “Save electricity” page you will find good tips to reduce your bill and consumption.

The two largest sources of consumption are electric heating and hot water. If the temperature in the house is lowered by one degree, and a saving shower is replaced, you will save electricity.

The tips on the page show how much you want to save in kroner, and how many kg of CO2 such as switching to a saving shower means.

The tips also state how many of the users (in%) of those who have answered the questions in the app use or plan to use an energy-saving shower.



Use energy-saving shower

NOK: 1000
CO2 (kg) without guarantee of origin: 530 kg
CO2 (kg) with guarantee of origin (Norwegian hydropower): 16 kg
If you use the shower for a quarter of an hour every day, you will save about 1000 kWh, which is NOK 1,000 a year on an energy-saving shower compared to a regular shower. By reducing the number of minutes in the shower, you save even more.

Lower the indoor temperature by one degree

NOK: 1000
CO2 (kg): 530 kg
If the temperature is lowered a degree in a home that uses 20,000 kWh per year, the savings will be approximately NOK 1,000 per year.

Lower to below 15 degrees in unused rooms

NOK: 1200
CO2 (kg): 636
If your home uses 20,000 kWh per year, and you lower the temperature to below 15 degrees in 20% of the heated area, you will save approximately NOK 1,200 / year.

(if your home has 100 m2 of heated area and you lower the temperature to below 15 degrees on 20 m2)

If you have a room with an oven of 1 kW and this is on for 1000 hours per year to give a temperature of 20 degrees. If you lower the temperature to 15 degrees, you save 275 kWh, according to an energy boost.

Savings: 275 kWh * 1 kroner = 275 kroner

If you do this in three rooms in the house, the saving will be 825 kroner per year

Close the door to cold rooms

NOK: 1200
CO2 (kg): 636
If you have a cold room where the temperature is 15 degrees and you have the door open to a warmer room where the temperature should be 20 degrees, the heat will go from the hot to the cold room. The heaters in the hot room must then use more power to maintain the temperature.

Savings: 275 kWh * 1 kroner = 275 kroner

If you do this in three rooms in the house, the saving will be 825 kroner per year

Switch to LED light bulbs

NOK: 900
CO2 (kg): 480
It is no longer allowed to sell incandescent lamps, and a good alternative is LED. They are more expensive to purchase, but last the longest and save energy, and will therefore pay off in the long run. What you save depends on how many hours the lamp is lit and how powerful it is, but a rule of thumb is that you save close to NOK 100 per point of light per year. If you replace 10 lamps, you can calculate NOK 800-1000 in savings per year.



CO2 emissions are taken from NVE’s product declaration for 2016.

For customers who do not buy a guarantee of origin, the product declaration (where the electricity is produced) has a composition as shown below:

Renewable power: 14%
Nuclear power *: 21%
Thermal power (fossil fuels): 64%
Furthermore, the AIB’s calculation states the following CO2 factors:

Coal power: 1119 g / kWh
Gas power: 525 g / kWh
Wind power: 18 g / kWh
Nuclear power: 13 g / kWh
Hydropower: 5 g / kWh
Using emission figures from the technologies as above, the CO2 factor for Norwegian power production can be estimated at 16 g / kWh in 2016.

It calculated a CO2 emission of 530 g / KWh related to the national product declaration. This does not reflect CO2 emissions related to Norwegian power production, but is a figure for the relationship between power and CO2 emissions within the schemes with product declarations and guarantees of origin based on the RE-DISS project’s calculation method.
