3. After use, do not leave the devices on standby
For this purpose, for example, an electric power strip equipped with an ON / OFF button can be used. According to some estimates, this can save on average around € 100 per year. An example can give you the idea: a good model of smart TV of a well-known brand, of medium size (43 “) consumes 65W when it is switched on, while when it is in standby connected to the internet and with the bluetooth option, it consumes, in addition to contribute unnecessarily to electromagnetic pollution, 6.5W, of which 3W for LAN, 3W for Wi-fi, 0.5W for bluetooth. So assuming that the television is on average for 4 hours a day and for the remaining 20 hours it is in standby, the consumption will be equal to 94.9KWh / year due to the actual use of the TV and 47.45 KWh / year due to use on the stand. -by of the TV. If you consider that there is no technical reason for leaving the television on standby, unlike the mobile phone, it is easy to realize that 47.46KWh / year is a waste of electricity and money.
4. Do the maintenance of the systems
A well-maintained electrical system or device consumes and pollutes less.
5. Avoid using the heating / cooling system without taking into account actual needs
In particular, it is necessary to adapt the use according to: a) external temperature, b) number of people in the room, c) humidity level, d) actual presence of people in the heated / cooled rooms, e) opening of doors and windows. Adopting a timer-thermostat and thermostatic valves (if not yet installed) is a useful aid in running the systems.
6. Promote proper thermal insulation between the house and the external environment
Shield windows at night or during hot hours by closing shutters and blinds or using curtains.
7. Use electrical appliances efficiently
Use dishwashers and washing machines with full loads to avoid repeated washing and preferably in the hours when energy is cheaper, avoid keeping the lights on in rooms where there is no one and adjust the intensity according to the actual lighting needs. Finally, one last piece of advice: when you go on vacation, it is advisable to turn off the heating / cooling system and disconnect all the devices connected to it from the electricity grid.
