The TOP energy consumers at a running time of 4 hours.
Since people in the lamp industry say the usual operating time of a bulb is approx. 4 hours per day our example is using these numbers as well. Not every one of you will have the lights on for so long but lets just assume this and compare all kinds of devices on a 4 hrs basis. Of course, it all depends on whether you still have old energy guzzlers or modern energy efficient appliances in use.

Note: there here are only examples with an electricity price of 0.28 € per kWh for units with mediocre power consumption. Calculating the drying and wash process we use 1.3 hrs for a complete run. (Last update: 2014)
You can see in our ranking that the real power consumer is the dryer.
But since it’s of course easier and cheaper to replace a bulb any energy advisor will probably initially start with these things before he advises to replace such an expensive device like as a dryer. There is also the possibility to dry your laundry on a clothes line and so save the occasional drying process.
It should also be remembered that we don’t have a dryer in every room, but probably at least one lamp connection. So e. g. in a 3-room apartment there are at least 6 lamp connections, which would cost a total amount of 4 hours of continuous operation with 60W around € 0.36 per day, per week ie € 2.52 and per year approximately € 130.
Therefore, it makes sense to exchange bulbs with the latest energy efficient models, as it’s relatively easily to reduce electricity costs. Nevertheless: don’t change every bulb at all cost. It’s really important to think about where you use your lamps the most? This will usually be the living, dining and kitchen area. Hardly any of us have a light 4 hrs. lit up throughout the whole year. A detailed research of one’s own “light-switch behavior” is worthwhile and clearly shows the location of the power-hungry bulbs.
