We constantly use energy in our daily life, and we can’t even imagine life without. Every house has electricity, a heating system, and we are using computers, television, radios and other devices every day. All these devices use a lot of energy, even when they are not in use.In Europe heating causes the largest energy consumption in private households. It takes almost 70% of all produced energy.
As we can see, we use a lot of energy in one year. We also must not forget the energy, that is lost even when devices are not in use, even when they are not working.
That is why we need to save energy everywhere and anytime.The savings can be significant, when we take care for the environment.
According to the statistical calculation, the average electricity consumption in households is 290 kWh per month. Unfortunately this information is not very useful, because households are different. Consumption depends on household the size of the equipment with electrical appliances and the quality and intensity that electrical appliances are used.
