A new generation of household appliances can help to significantly reduce the consumption of electricity in the home. Of course, it is unthinkable to immediately replace all existing devices with energy-saving ones, but even the gradual replacement of outdated or obsolete equipment can help improve the energy consumption parameters of the home.
Energy-saving appliances
Refrigerators
The first energy-saving appliances we look at can save a lot of money by reducing energy consumption in the home. After all, these devices work day and night, so it's best to choose them carefully. These are refrigerators. The technological innovations of almost all manufacturers are inverter motors. They are very quiet and allow you to regulate the energy consumption of the device, avoiding consumption peaks. By keeping the temperature constant and uniform, it was possible to optimize energy consumption and increase the efficiency of the refrigerators.
Several manufacturers have developed a technology with which it is possible to better preserve food by differentiating the ventilation in different compartments. The release of active oxygen in modern models prevents the formation of bacteria. Energy-saving refrigerators made by the South Korean company, in turn, use insulation panels more efficiently. They are much thinner than the materials used just a few years ago. This means that modern refrigerators have become more energy efficient. More space for food, but less energy consumption to cool it. Recently, American researchers ranked refrigerators accordingly in the top positions in the energy saving ranking. These energy-saving luminaires consume as much as a 20W lamp. This result was achieved thanks to effective insulation, seals, new variable speed compressors and, again, the shape and position of the evaporator and condenser.
The results of other studies conducted in the US could convince even the most undecided to change refrigerators. In 12 years of purchasing a new model, the reduction in energy costs related to an old appliance can be several hundred dollars. The most energy efficient models are those with a freezer at the top of the refrigerator. At the same time, side-by-side refrigerators have the worst indicators of energy efficiency.
dishwasher
From a technological point of view, modern dishwashers not only consume less energy, but also much less water, and the adjustable baskets allow you to optimize loads. German manufacturers also use the properties of natural zeolite, a mineral that absorbs moisture during washing and releases it as steam during drying, making the last stage of the cycle faster and more efficient.
Washing machines
Modern washing machines provide differentiated washing cycles to reduce the consumption of water and detergent. Extensive research has shown that the cleaning process does not depend on the temperature of the water and the detergent used, but is a consequence of the mechanical action of the drum. In this regard, new solutions have appeared, for example the washing machines developed by the company introduce air bubbles into the drum, which allow the detergent to penetrate better into the fabrics and to wash well even in cold water.
Induction cookers
Induction hobs are becoming increasingly popular, even among the lines of energy-saving appliances. They cook food by creating an electromagnetic field that heats only the bottom of the pots. As a result, there is no loss of energy. You save, considering that the efficiency of these devices reaches 95%, while in traditional gas stoves there are losses of the order of 30-60%.
Vacuum
How do watts convert into the useful work of a vacuum cleaner? Not much if the vacuum system is not efficient. The only thing you can tell by looking at the watts indicated on the energy label is the power draw. But what if all this energy is used inefficiently? The new energy-saving appliances offer good guarantees. The vacuum cleaner models with cyclone technology have the advantage of not having a dust bag. The suction power remains unchanged, which benefits the energy efficiency of the apparatus.
Energy efficiency label
After making sure that appliances can help save energy in the home, all that remains is to choose the right model. There are a lot of offers and it's not that easy to navigate. The first thing to do is to pay attention to the energy efficiency label, which gives a clear idea of energy consumption.
The horizontal arrows at the top indicate the energy efficiency class, which can range from A +++ (best) to G (worst). The color of the arrows also indicates the degree of energy efficiency of the equipment: from red for the high energy consumption classes to dark green for the most energy efficient appliances. The arrows show the energy consumption in kWh per year based on laboratory tests, i. e. under optimal conditions. Knowing the cost of electricity, one can easily determine the annual cost of electricity, which obviously also depends on how the device is used.
