Cost explosion: What can be done against the steadily rising prices for electricity, gas & fuel?

First the gas supplier says that he would like a good 30 percent more for the natural gas supplied, then the electricity supplier demands 10 percent more. In addition to the CO2-Prices are also due to the increased costs on the energy market for the higher prices.

When gas and electricity get more expensive, this is a good opportunity to look for energy guzzlers. No matter how big the household, there is always potential to save energy. Every kilowatt-hour saved is not only easy on your wallet, but also reduces your own CO2-Footprint.




Energy prices will explode in winter 2021/2022. A good time to optimize the energy requirements in your own four walls and thus reduce costs. Our series of articles with the focus on saving energy costs shows how and with what this works.

But where do you start? Our article provides good tips with energy saving tips in the digital environment. It helps to expose power guzzlers and shows where costs can be saved through better configuration or targeted new purchases. In addition, he does away with some energy-saving myths.

We also asked ourselves whether a smart electricity meter helps people use energy more consciously and what else these new, communicative boxes can do.

If you find so-called heat cost allocators on the radiators in your home, you should take a look at our instructions, which describe how to read them out by radio.

Price increases are also a good opportunity to look around for cheaper suppliers. We have summarized what needs to be considered when using price comparison and switching portals. The stumbling blocks described for changing electricity suppliers also apply to comparable portals for gas suppliers.

We took a closer look at a supposed energy saver, the so-called “Voltbox”. The small box should save “up to 90 percent” on the electricity bill. Such a miracle thing for 59 euros can actually only be useless rip-off, right?

Using electricity and heating energy as sparingly as possible, changing suppliers, these are the adjusting screws that anyone can actually turn. It becomes more difficult with the other energy costs, because petrol and diesel are also becoming more and more expensive. Not everyone who commutes to work every day can switch to bicycles. Whether local public transport is a sensible and inexpensive alternative to owning a vehicle depends above all on where you work and live. Sometimes carpooling is the only way to save. Or you can arrange to work from home: every fixed home working day per week saves commuting costs.

The switch from the combustion engine to the electric car also needs to be well thought out. On the one hand, an e-mobile like this is still expensive fun despite subsidies. On the other hand, the framework conditions must also be right. A charging point in front of your own house, which is fed via the photovoltaic system on the roof, would be ideal. This luxury is mostly reserved for the better-off homeowners. After all, a solar system with a sufficiently dimensioned storage battery is a big investment, even if it is currently subsidized with cheap KfW loans.

In c’t 25/2021 we declare war on rising energy prices. Those who identify power guzzlers, adapt their own behavior and optimize their domestic electricity tariffs can save a lot. We are clearing up energy-saving myths and unmasking an energy-saving placebo. We also tested 55-inch mid-range TVs and suitable video streaming services. You will find issue 25/2021 from November 19th in Heise shop and at the well-stocked newspaper kiosk.
