Turn off equipment not in use

The essence of the measure includes turning off any kind of equipment which currently is not needed for the defined time period. As the rule of a thumb we shall consider that it may be effective if the time in a turned-off mode is at least 4 times more than the time of "switch on" and "switch off".

This means that for short time periods turning off is not effective and is not included (for example 1 minute break for computer working session does not require turning off and on the computer, as its turn off and turn on time is also ca. 1 minute, etc.).

Examples of equipment are typical home-based equipment "service-bases": computer/monitor, notebook, printer, TV, X-Box, electric training equipment, smartphone (connected to socket), music equipment, synteizer, router, etc. Typical installed capacity of such equipment for average appartment is 400-700 W.

Usually it works in average for 4-6 hours/day (at least main part of it).

The optimization of turning off may provide up to 5% economy (i.e. 0.2-0.3 hours or 12-18 minutes). For consistency and conservativeness let's say that 50% of installed capacity may be used in once (550/2=275 W).

Then the daily economy is 275 W*5 hours=1375 Wh * 5% = 68.7 Wh.

Then, for the year it will be 68.7 Wh * 365 =25 000 Wh (25 kWh). Bearing in mind that the average annual consumption for average appartment is 100 kWh/month (1 200 kWh/year), it will comprise at least 2% (and up to 5%) from total consumption/ bills.
