The biggest power guzzlers in the household

The biggest power guzzlers in the household


Around 30 percent of households in Germany do not know their power consumption. By contrast, anyone who knows where the power guzzlers are in their own four walls can significantly reduce their electricity requirements through efficient use.

Over the past 15 years, the price of electricity for private consumers has almost doubled. The only way to sustainably reduce energy costs is to use household energy consciously and efficiently.

However, to save energy it is important to know what household electricity is used for and where the biggest power guzzlers are are located. Smart home creates innovative possibilities to track and regulate power consumption.

Hot water treatment with power consumption at the top

The biggest power guzzler in the household with the most savings potential is the electric hot water supply - if available. As statistical surveys by EnergieAgentur.NRW on the basis of household surveys show, the proportion of hot water is around 28 percent of household electricity consumption. Already with two persons around 250 euro become due per year for this item. For four persons, the calculations of the energy experts show more than 420 euros per year. If you take a conscious shower and bath, you can reduce your electricity consumption considerably.

Another big consumer of electricity is air conditioning. They are also enjoying increasing popularity in Germany and, depending on the design and use, they can drive up the electricity bill enormously. Especially mobile air conditioners are very energy hungry and work extremely inefficiently with their exhaust hose. Various measurements show that consumption of 500 to 600 kilowatt hours and above is not uncommon in the warm season. Thus, a mobile room air conditioner generates around 150 to 180 euros additional electricity costs. Tip: Commercially available fans are much more frugal and require only 30 to 50 watts.

TV and Game Console: A Dangerous Combination

According to the EnergyAgency.NRW surveys, around twelve percent of the annual electricity demand is in the TV / audio sector - for four people average just under 150 euros. There are many indications that the costs will increase in the future with the screen diagonal. It is particularly expensive when the TV is used together with older game consoles. For three hours a day game beat XBOX 360 and Playstation 3 with about 30 - 35 euros to book. In addition, there are again about 30 - 40 Euro electricity costs for the TV, which must be considered. Even playing DVD's and blue-rays is relatively expensive. Depending on the playback format, XBOX 360 and Playstation 3 consume between 2.5 and 15 times more than a standard player.

The subject of lighting is of decreasing importance, however. Currently around ten percent of the electricity demand in Lampen & Co., this value is likely to decrease significantly in the future due to the increasing use of energy-saving lamps and LED lights. For example, modern LEDs consume up to 90 percent less electricity than conventional light bulbs.

Expensive standby: consistently shut down devices

Stealthy consumers are above all stealthy consumers. Especially older devices often have a high standby consumption. According to calculations of the German Energy Agency alone, the standby operation of all household electrical appliances costs an average of 115 euros a year. Here only helps consistently turn off the devices. Switchable sockets, which are already available for a few euros in the specialized trade or DIY store, are recommended as a practical and economical solution.

Other large consumers, especially from the kitchen - refrigerator (200 - 300 kWh per year), dishwasher (200 - 400 kWh per year), electric cooker (250 - 500 kWh per year) and the bathroom - washing machine (150 - 300 kWh) are however, as such much better known. Expensive it gets especially when old refrigerators get a second life as a drinks cooler in the garage or basement. Clothes dryers (200-700 kWh per year) can also push up the electricity bill significantly, depending on the design and model. Even more expensive to maintain are usually washer-dryers, which both wash and dry and are generally less energy-efficient than two individual units.

Ammeters and smart meters help in the search for energy guzzlers

Who reduces the energy consumption of individual appliances and their use wants to check connected costs, who can buy even for small money an ammeter or borrow at many local municipal utilities. Placed between the socket and the plug of the device, they indicate, among other things, the current consumption, the consumption over a certain period of time and the associated electricity costs. There is an increasing number of so-called smart meters, which are intelligent electricity meters that allow more precise analysis of energy consumption. Since 2010, smart meters have been a must for new buildings and complete renovations. It is planned to equip around 80 percent of households with an intelligent electricity meter by 2020.
