Modern way of life imposes the need for a rational approach to the use of all resources. The very concept of sustainable development is based largely on this idea. We are witnessing the increased consumption of electricity and other forms of energy. The trend of growth in energy consumption occurs in the whole world. The development of alternative technologies leads to the production of new devices that are used for energy saving in households or industry.
The most widespread way of electricity saving is rational energy consumption and savings. We simply should spend energy just as much as we really need it and do not act extravagantly. Regardless of whether we talk about technical or non-technical measures, all measures include the same (or even higher) level of comfort and standards. The most common energy saving measures relate to three main areas of application in every household:
- Heating and cooling
- Household appliances
Heating and cooling
Over 80% of household energy is spent for space heating/cooling or water heating. This represents a large share of total energy consumption, but there are many measures to reduce these costs.
- Thermal insulation – Make sure that doors and windows are sealed well. Insulating tapes are one of the cheapest solutions to preserve heat, but a complete insulation of residential units is the best solution for energy saving.
- Electric heaters are large consumers of electricity, and use them only as a temporary solution for heating.
- Heating boilers and radiators – The capacity of the heating boiler and radiators need to match the size of your facility. If you have a heating boiler that is 50% greater capacity than required, the cost of heating may be increased by 15%. Installing thermostatic radiator valves can save up to 20% of the energy for heating.
- Air conditioning – The most efficient appliances on the market are inverter air conditioners, and they achieve energy saving of 20 to 40% compared to standard cooling devices. If the exterior of the air conditioner is in the shade, it consumes 10% less energy. Cool only the rooms in which you reside!

- Water heater consumes about 15% of the total electricity consumed in a household. Set the water heater to a temperature between 50 and 55°C, and you will achieve significant energy saving.
- Fridge works most efficiently at temperature between 3°C and 5°C (the freezer at 0°C). Set refrigerators and freezers to a cooler location in the house, and avoid their exposure to sunlight.
- Washing machine and dishwasher can save energy if they are filled to the max.
- Stoves and ovens – Always put lids on pots, heat only the required amount of water, never heat an empty hob, and so on.
Illumination has a share of about 3% of the total electricity consumed in the household (similar to a refrigerator). Turn off the light when it is not needed, especially in hallways. It is the simplest and cheapest measure, without any initial investment. Use light bulbs of different power (W) for different purposes. Also, use one high power bulb instead of several smaller.
Today, there are many light bulbs that consume less electricity and have a longer shelf life than conventional bulbs. These are the so-called “energy saving light bulbs”, such as CFLs (compact fluorescent lights) and LEDs (light emitting diodes). They spend 3-4 times less electricity than incandescent light bulbs, last 10-15 times longer and contribute to significant energy savings.
