Baden-Württemberg's Prime Minister Winfried Kretschmann has just made a name for himself with new tips for saving energy. The number of good tips grows almost exponentially with the gas price. But what is particularly noticeable in the wallet of the consumer? Stiftung Warentest has now investigated this question.
The result is not surprising. The adjustment screws are greatest when showering and heating. Green Kretschmann, who months ago recommended the now famous "washcloth" instead of the daily shower, was right. The foundation calculates the savings using the example of a family of three, who were able to save a total of 1074 euros a year with just a few adjustments.
The example family does the following: They install a water-saving showerhead that only runs 7 liters per minute instead of 14. The shower time is reduced by a few minutes, saving 2633 kilowatt hours of electricity a year. Everyone showers one degree cooler and with these measures the family saves 707 euros a year.
In order to reduce heating costs, programmable thermostats are installed that turn down the temperature at night and when nobody is at home. By temporarily lowering the temperature by four degrees, you save seven percent on heating costs and thus around 95 euros, according to the Stiftung Warentest.
This conversion is even more worthwhile in an uninsulated apartment than in an insulated new building. Together with other measures, such as using the washing machine's eco-program and baking with convection, the family finally saves 1074 euros a year.
Shower less, live colder – these and other savings tips have recently come from politics. But how do people on the street feel about such advice? WORLD asked people around.
