Expert power-saving tips that really help

The increase in costs makes it clear that electricity is a valuable commodity. If you don't want to burden your wallet any further in the coming winter, it is worth taking a closer look at your own electricity consumption. In an average household, refrigerators and freezers, entertainment electronics - but above all hot water preparation using electricity - are among the largest consumers. A lot can be saved with simple means and without loss of convenience.

Here you can read some tips on how even small measures can reduce power consumption. Those who follow these can save a lot of money a year.

1. Super easy: Switching off sockets instead of standby can save up to 100 euros in electricity costs a year

Many employees leave their computers and printers switched on when leaving the office. The stand-by mode of many electrical appliances alone leads to total costs in households and offices of between 5 and 6 billion euros. Electricity costs, which could be avoided very easily, would simply turn off the devices completely in the evening. By completely switching off the television, receiver, computer, printer and monitor, the annual consumption can easily be reduced by up to 400 kilowatt hours. This can also be done very easily with master-slave connector strips (from 20 euros). B. the television switches the connected devices on and off.

Especially on vacation: switch off everything that is possible

Whether it's a city trip or a safari vacation - anyone who travels should remove as many devices as possible from the mains. Because one thing is certain: Saving electricity while on vacation has a positive effect on the environment and the holiday budget.

2. Energy-saving dishwashers and washing machines - potential savings of around 50 euros

A dishwasher is practical and uses less water and detergent than washing by hand. Those who now switch to energy-saving devices can save up to 26 euros per year. The same applies to washing machines: energy-efficient devices cost 21 euros less per year. Therefore, when purchasing a new machine, you should keep an eye on the energy efficiency class of the device; it is best to choose class A +++. Practical tips: Always charge the machine completely and do not wash too hot. This not only helps the environment, it also helps you to save costs and the laundry to keep its shape and color. This is ensured primarily by modern cold detergents, which also deliver perfect results at 40 ° or 30 °. A normal wash cycle at 40 degrees quickly consumes 0.6 kWh as opposed to 0.1 kWh at 30 degrees. You can save quite a bit of electricity with it over the course of the year.

3. Save 70 euros annually on electricity costs by drying without a dryer

When drying laundry, the following applies: a tumble dryer without a heat pump costs a good 70 euros a year, with a heat pump it is only 24 euros. But even then: dry as often as possible without a dryer! Use drying chambers on the floor or in the basement. In spring and summer, the laundry can then be dried outside again. If you do use the dryer: Spin the laundry at maximum speed beforehand.

4. Fridges / freezers: Use energy-saving devices and make up to 70 euros a year

You can save a lot of electricity with clever use of the refrigerator and freezer: By purchasing a refrigerator and freezer with the highest energy efficiency class A +++, you can save up to 70 euros per year - the price difference to a cheap refrigerator is back after two years. But the positioning of the device also plays an important role, because the warmer the place, the higher the electricity costs.

Fridges become more efficient through optimal utilization.

5. Computer: energy saving mode saves up to 65 euros a year

Many computers and laptops nowadays run alongside and consume unused energy. Here it is worth activating the respective energy-saving functions of the devices. The monitor switches itself off after just a few minutes and the PC goes into economy mode. Warning: screen savers are real energy guzzlers! They prevent the PC from going into a more economical hibernation state - be sure to deactivate it!

6. Laptop instead of PC and monitor saves 50 euros

Laptops are trimmed for economical consumption and draw a good 50 percent less power from the socket than a comparable PC. Current notebooks can still compete with modern 3D games and HD videos and only cost a small surcharge compared to desktop PCs. This reduces electricity consumption by around 180 kilowatt hours a year and pays for itself after two to three years. If you like it even smaller and more economical, you can use an ultrabook or tablet computer.

7. Save electricity with LED lamps: the most important tips

We got used to the light bulb, we grew up with it. It has been with us in everyday life for more than 100 years, it was inexpensive and relatively reliable and we knew exactly what kind of light we were getting. The incandescent lamp had only one catch, it was a waste. For example, we had to pay for 100 watts of electricity, but we only got 5 watts of light. The rest was warmth.

With the departure of the incandescent lamp, the triumph of energy-saving lamps began. But they also have disadvantages. The usual light color is not always right, energy-saving lamps always take a little time when starting. The lamps often contain heavy metals, which make professional disposal necessary. A completely new world of lighting only opened up with the introduction of LEDs. The small "light emitting diodes" are not only more economical than energy-saving lamps, but also offer unique lamp shapes thanks to their construction. LED lamps can be screwed into existing incandescent lamp sockets as "retro fit" models.

This is how much electricity and money you can save with LED lamps

A typical household consumes almost 300 kWh of electricity per year for lighting. 80 percent of this can be saved immediately if you replace lightbulbs with LED lights. Calculated over a year, you will have around 70 euros more in your pocket! Of course, there are acquisition costs when switching to LED lamps. To replace 14 lightbulbs - that is how much an average household owns - you can generously estimate 112 euros. Under these conditions, the retrofitting will pay for itself after about 1 1/2 years.

LED lamps could, despite less power consumption, still use more electricity if you no longer pay close attention to turning off the light every time you don't need it, precisely because these LED lamps consume less electricity than the old light bulbs. This is called the rebound effect - all information about it can be found here.

LED instead of lightbulb - what to look out for

  • The brightness of a light source is actually measured in lumens. Most people have so far been guided by the watt number, by which one can estimate the brightness. But be careful: incandescent bulbs and LED lamps are not comparable in terms of their wattage, because LED lamps are much more energy-efficient! An LED lamp has significantly less watts than a light bulb with the same brightness. Most manufacturers indicate on the packaging which light bulb you can replace with which LED lamp. Here are a few rough guidelines: A common 60 watt light bulb is roughly equivalent to an LED lamp with 9 to 12 watts. You can replace a 100 watt light bulb with an 18 to 19 watt LED lamp.
  • Another important criterion is the color temperature or light color. With a certain wattage, light bulbs always had the same color temperature. This is different with LED lamps; you can buy them in different color temperatures, which are described with terms such as “warm white”, “neutral white” and “daylight”. A common 60 watt light bulb has roughly the same color temperature as a “warm white” LED lamp. Many people find this light color pleasant. In addition, with LED lamps you can choose between matt and transparent glass and between dimmable and non-dimmable versions.

8. Save electricity with electrical hot water preparation

Especially when the water is heated electrically, there are many ways to save electricity in the household. A saving shower head in the shower or bathtub can reduce consumption to the necessary level. Flow restrictors on taps also do a good job here. A thermo-stop helps when using boilers or under-counter devices. This means that water is only heated when it is needed. A boiler should be replaced by a water heater anyway, so the water is only heated when it is needed.

9. Power of habit - makes a lot of electricity!

Alarm clock off - light in bedroom on, light in bathroom on, light in kitchen on, coffee machine on, showering. Here two lamps are already burning too much - twice power consumption where it is of no use at the moment. It's a matter of habit, and it's hard to deal with. Instead of pouring the coffee into a thermos, the hotplate stays on. Owners of a fully automatic machine do not switch it off, because a second cup may be needed in order to become fully conscious. The current electricity bill is in the mailbox - and suddenly you're wide awake even without a second coffee.

New habits for saving electricity

And these are just a few examples. How often are the PC and television running even though they are not in use? Sure, it could be that you have to check your e-mails again or that an interesting program happens to start. But in the end, these are just excuses to cover up habits again. Does a dishwasher that is only half full have to be switched on because of a single plate? Hardly likely. Simply washing the plate by hand would be faster and save electricity. And yes, here laziness joins habit to a certain extent.

Reason enough to look at the activities for a day and write them down if necessary. This can in fact reduce power consumption considerably. All that is needed is consistency. The reward will come at the latest with the next electricity bill.

10. Save electricity in the kitchen

Kettle or stove: what is more energy efficient?

A kettle instead of a pot on the stove - this way you can reduce power consumption and consequently save a lot of money. Up to 50 percent less (eco) electricity is required if the same amount of water is not boiled in the pot on the stove, but instead in the kettle. Even if the optimal pot size including lid has been selected and the heating process takes place on a ceramic hob, the kettle is around 35 percent cheaper in terms of power consumption. Only gas and induction stoves can reach the values ​​of the kettle in terms of consumption.

More energy saving tips for the kettle

To ensure that the power consumption is not unnecessarily increased, you should pay attention to the correct operation of the device.

  1. Only fill in as much water as is actually needed!
    Would you just like to prepare a cup of tea? Then it is understandably not necessary to use the entire volume of the stove and fill it to the brim. The less water has to be heated, the lower the energy consumption. So only heat the amount of water that you actually need. The right amount can be easily measured and filled with the appropriate cup.
  2. Use the temperature controller!
    If your kettle is equipped with such a regulator, you should also use it, because it also helps to save electricity. Often, boiling hot water is not needed at all. For example, 60 ° C is sufficient for green tea.
  3. Avoid losing energy when cooking!
    If you need large amounts of boiling water to prepare pasta or potatoes, there is no point in preheating this water in the cooker and then pouring it into the saucepan. The resulting energy losses are too high to make up for the time saved. This also applies if you only want to heat part of the water in the kettle. In principle, the following applies: the greater the amount of water that you want to heat, the lower the heat losses on the stove top.
  4. Descale the kettle
    Limescale deposits can significantly reduce the life of your kettle. In addition, its performance is impaired, which in turn increases the consumption of electrical energy and can damage the heating elements in the long term. One of the most important tips to save electricity in this context is therefore: descale the stove regularly!

There are numerous chemical agents on the market for decalcifying household appliances such as coffee machines or kettles. The good old household remedies vinegar essence and citric acid are cheaper and more environmentally friendly. Simply put some vinegar or vinegar essence in the cooker, fill up with water until all limescale deposits are covered and then switch on. After the water-vinegar mixture has been brought to the boil, the kettle can be rinsed out. To be on the safe side, it is advisable to fill it completely with water one or two times before using it again and bring it to the boil so that the last residues and smells of the vinegar evaporate.

Save electricity with the oven

Preheat the oven and leave it on until the end of the cooking time? You can find all information on this here.

11. Curb the power guzzler air conditioning

Air conditioners are at the top of the list of household power guzzlers: you pay for pleasant cooling at the push of a button with an electricity bill that is around 15 percent higher, the air conditioners are comparable to a large refrigerator: their job is to keep a room permanently cool while outside significantly higher temperatures prevail. But heat usually only knows one way, namely from a warmer to a cooler place. In order to permanently maintain a temperature gradient, a lot of technical sophistication is necessary - and above all a lot of electricity. Not only condenser and compressor have a high energy requirement, the fans of the air conditioning system also need electricity in order to then distribute the cooled air in the room.

A mobile air conditioning system that is in operation for around 30 days for 8 hours in summer consumes around 600 kWh of electricity during this time. That is around 10 to 15 percent of the annual electricity consumption of a family of four! You put more than 130 euros in the air if you regulate the room temperature in summer with the air conditioning.

Air conditioning: power consumption depends on the type of device

But air conditioning is not just air conditioning. There are different types of devices on the market that work with very different levels of efficiency. A rough distinction is made between two types: small mobile devices (so-called monoblock devices) and permanently installed split air-conditioning systems.

1. Mobile air conditioning (monoblock device)

Mobile air conditioning systems dissipate the room heat to the outside via an exhaust hose. To do this, a window must remain open permanently, through which warm air flows in from outside. It's like leaving your fridge door ajar all the time! A mobile air conditioning system is therefore only cheap to buy, but with permanent operation it becomes a real power and money destruction machine.

2. Split air conditioning

Modern split air conditioning systems with inverter technology switch off automatically as soon as the desired room temperature is reached and do not need an open window. As a result, these devices are significantly more energy-efficient than the small monoblock devices - they use less than half the electricity. However, they are more expensive to purchase and their installation requires a breakthrough in the wall.

3. Fans

No air conditioning in the traditional sense, but at least the most energy-saving alternative: room fans provide a breath of fresh air, but consume significantly less electricity than air conditioning systems. Definitely the better solution compared to mobile monoblock air conditioners!

12. Power tips at Christmas time for a cheaper party

At Christmas it can be a little too much: Eat too much, drink too much - and use too much (eco) electricity. While the first two practices can still be booked under “typical Christmas exception” and, in the worst case, are accompanied by a bad conscience, the electricity consumption is a bit more specific, namely in the form of a higher bill.

  • Do not let luminous jewelry burn for too long
    At Christmas time the days are short and the nights long. So there are ideal conditions for fairy lights and other luminous decorations. But it doesn't have to announce the festive mood all night long and should be disconnected from the grid in good time to save electricity.And that can be quite a lot: a single chain of lights with 10 lights with a consumption of 25 watts each requires around 70 kilowatts of electricity if it is in operation for eight hours at a time. The use of a timer is worthwhile here to prevent the chain of lights from shining for an unnecessarily long time.
  • The more economical alternative: LED light jewelry
    If you want to invest in new decoration, you should turn to the LED fairy lights. All information about LEDs can be found above.
  • Energy efficient Christmas cookies
    The oven is also used more often than usual at Christmas time. Therefore, there are also some energy-saving tips to heed that you can find here.

But why should you save electricity and energy?

Those who use scarce resources more sparingly benefit in several ways. After all, many energy sources and the infrastructure necessary for energy generation (e.g. power plants and lines) are only available to a limited extent. In this respect, saving energy not only has a positive effect on nature, but also has political and economic advantages.

Reason 1 to save energy and electricity: reduce costs

Those who use less energy will save in the long term. For this reason, it is worthwhile to use energy more sparingly and to try to improve energy efficiency. Those who use less energy are less dependent on future price increases and can thus relieve their budget - this applies to households as well as companies.

Reason 2 to save energy and electricity: Minimize the impact on nature and the environment

The fact is that energy consumption can have devastating effects on the environment. The combustion process creates sustainable environmental pollution when generating electricity and heat (e.g. in power and heating plants as well as in industrial processes). Depending on the energy source - gas, mineral oil products, biomass or coal - different gases are released during combustion. And that's not all: The resulting waste products such as fine dust, greenhouse gases (e.g. methane, CO2) and nitrogen oxides (NOX) have a negative impact on the climate, the environment and people.

What many do not know: More economical energy consumption can also avoid high social costs. The higher the environmental pollution caused by energy consumption, the more the costs in the healthcare system and the costs of building noise barriers and the like can rise. In this respect, not only nature benefits from low energy consumption, but every individual.

Reason 3 to save energy and electricity: reduce dependency on energy supply

It is easy to understand why economical electricity / energy consumption has ecological and economic advantages. But what does energy have to do with politics and economics? The answer is: quite a lot. Fossil fuels such as coal, natural gas and oil are only available to a limited extent and are obtained in a laborious (and expensive!) Way. Since fossil fuels are only available to a very limited extent in Europe, there is a high level of energy dependency on other countries. The problem: Fossil fuels are needed worldwide and are therefore in great demand. Apart from that, the energy sources often come from geopolitical crisis regions.

Even switching to renewable energy sources such as biogas does not mean that you can use unlimited energy. Since wood, energy crops and the like are only available in limited quantities, they also have to be imported if they are used more. Thus, economical energy consumption reduces the energy dependency on foreign countries as well as strong price fluctuations.

Those who save more electricity and energy and increase energy efficiency through modern systems and Co. protect the environment, their wallets and contribute to a better life for the general public. The cost-benefit ratio is right in every respect - whether for small households or large companies.

Consume less energy / electricity and increase energy efficiency - these are two goals that everyone should achieve for the sake of the environment.
