1. It is better not to turn off the lamps when you go out for a short while because more electricity is needed when you switch on and off.
Answer: It does not draw any extra electricity to light and extinguish. Turn off the light when leaving an empty room.
2. It is better to have the Christmas lights around the clock than to use a timer.
Answer: If you have incandescent bulbs in the Christmas lights, it always pays to have a timer that automatically turns on and off. If you have modern LED lights, it won't always pay off with a timer, because the lights draw very little electricity. The timer can increase energy use because it draws electricity into standby. When you buy a timer, ask for energy usage.
3. You can save money and energy by lowering the indoor temperature at night.
Answer: Heating is a big part of your energy use. You can save both money and electricity by lowering the indoor temperature if you have electric heating.
4. Leaving the charger in the socket does not draw any extra power when the battery is fully charged.
Answer: A tip: Feel your charger, if it is warm it draws power, is it cool then it has low standby consumption. For safety reasons, it is always best to unplug the charger when not in use.
5. TV, computer and other devices in standby draw no or almost no power.
Answer: This applies to newer appliances that have the highest permissible energy consumption in standby. Older products may have higher energy consumption in standby. Standby requirements have been gradually tightened, a newer product usually has a lower standby than an older one.
6. Solar panels do not work when it is cloudy.
Answer: We have a good climate for solar panels in Sweden. Solar panels work even when cloudy, but produce less electricity compared to a sunny day.
7. Oil-filled elements draw less energy than electrical elements.
Answer: Here we talk about direct-acting electric heating. Oil-filled electrical elements mainly provide a more even heat than older elements for direct-acting electricity, which either goes too full or are switched off. My advice here would rather be: If you have direct-acting electricity then make sure you have a good control and control system so that the heat is regulated correctly. You get a more comfortable indoor climate while reducing heating costs.
8. Older houses are great energy thieves compared to newer ones.
Answer: If you have not done any energy saving measures in an older house, this may be true, but you can do much in an older house to reduce energy use and heating costs. Hot water turnover is one example. How often and how long you shower, for example, is of great importance for how much hot water is needed.
