Power consumption: TV’s cost per hour
Hardly anyone knows what an hour of watching TV really costs. Stromtipp.de has put together a small table with the most modern household appliances. In reality, the values can differ considerably, because in the case of old household appliances, the electricity consumption is usually higher.
Household electricity consumption – TV and computer consume the most electricity
The average electricity consumption of a German household is currently 25.6 percent to the account of TV / audio and office. The computer usage per day and household is estimated to be almost five hours, according to the study “Power consumption by application of private households” commissioned by HEA, BDEW and EnergieAgentur.NRW. In addition, the power consumption of routers, printers, various recording and playback devices, SAT receivers, antenna amplifiers, faxes and modems.
In addition, these devices not only increase the electricity consumption of a household during the period of use but also does not stop the power consumption even in stand-by mode. At an average power consumption of 3,091 kilowatt hours per household and year, according to the study accounted for about 760 kilowatt hours on these devices. The share of the average electricity consumption of washing machines and dishwashers also increased. The study points to the higher market saturation of electric tumble dryers and dishwashers.
Electricity consumption of refrigerators and freezers has decreased
On the other hand, the average electricity consumption of refrigerators and freezers has decreased significantly in recent years.
In the case of particularly efficient appliances with the energy class A +++, electricity consumption could be reduced by 73 per cent compared to 1997 devices. Against refrigerators and freezers of energy class A +, electricity consumption is significantly lower. Devices of energy class A +++ are only content with half.
Electricity consumption of electrical appliances
Do you want to calculate the electricity consumption of a specific electrical appliance? Nothing easier than that:
On each electrical appliance, you will find the power rating of the electrical appliance in Watts (W). To calculate the current consumption, multiply the performance with the average hours of use per day and the average usage days per year. Then you divide the result by 1,000:
Power requirement (W) x hours x days / 1,000 = Power consumption in kilowatt hours (kWh)
Electricity and electricity
To determine the electricity costs of a specific electrical appliance, multiply the electricity consumption in kilowatt hours with their electricity price:
Power requirement (W) x hours x days x electricity price = electricity costs
According to the Federal Association of the Energy and Water Industry (BDEW), the average electricity price for a current consumption of 3,500 kilowatt hours per year is currently 29.1 cents per kilowatt hour.
Power consumption: Spitters or spendthrifts?
In order to be able to assess whether their own electricity consumption is rather sparing or lavish compared to the average, the Confederation of Energy Consumers has prepared a formula. The formula for assessing your own electricity consumption from 2006 is based on the living space, the number of people and the number of household appliances. The formula is based on a detailed analysis of the consumption behavior of approximately 17,000 households.
(Washing machine, tumble dryer, refrigerator, freezer, dishwasher, electric cooker, microwave, electric heater, TV , Computer)
Is your actual electricity consumption 50 percent higher than the calculated value? Then you are one of the many consumers and could significantly reduce your electricity consumption.
Is your actual electricity consumption at least 30 percent below the calculated value? Then you belong to the frugal quarter of households.
Is your actual electricity consumption at least 50 percent below the calculated value? Then you are among the most economical five percent of the population.
