Average weekly cost
≈ 100 monetary units per day.
2 kWh * 50 monetary units / 1 day = 100 m.u.
Weekly Peak Power
≈ 2 kW.
7) After some minutes since 6), set the internal clock to the first day of the next
month, maintaining the 2000 W load.
Monthly energy consumption = 9 kWh.
Obtained by summing up (and rounding to the nearest integer value) 5 kWh from
the first week of the previous month, plus 2 kWh from the second week, plus 2
kWh from the third one.
Monthly cost
≈ 450 monetary units.
Obtained by multiplying 9 kWh by 50 monetary units.
Monthly CO2 emissions
≈ 4.5 kg.
In other words, (50 kg * 0.01) * 9 kWh.
Monthly Peak Power
≈ 3 kWh.
This value is a consequence of the few seconds the 3000 W load was connected.
Average monthly energy consumption = 2 kWh per day.
2 is the nearest integer to the result of dividing 9 kWh by the number of days (4) of
the previous month.
Average monthly cost
≈ 112.5 monetary units per day.
50 u.m * 9 kWh / 4 days = 112.5 m.u.
Average monthly CO2 emissions
≈ 1.125 kg per day.
Obtained as (50 kg * 0.01) * 9 kWh / 4 days.
8) After some minutes since 7), set the internal clock to the first day of the
following month (that is, two months from now on), maintaining the same load.
Monthly Peak Power
≈ 2 kW.
Average monthly energy consumption = 2 kWh per day.
The previous month consisted of only one hour, with a consumption of 2 kWh.
This total consumption is divided by only one day.
