In my task I would like to calculate the electricity consumption. I always find it interesting what you can calculate from the electricity. First I want to enter in the power consumption calculator the number of watts, in my case it is 5. Then I enter in the calculator the number of hours, which was then 2. At the end, I can calculate this using my formula (see above) and come to a result of 0.33 kWh. You can calculate the result either with a formula or with the electricity calculator. The solution should be the same.
Power (watts) x time (hours) = energy consumption in watt-hours (Wh), this divided by 1000 = consumption in kilowatt-hours (kWh)
What was also exciting to break out the electricity consumption in the year. What did I calculate?
Living space in sqm * 9 kWh + 4 people in the household * 400 kWh + 15 electrical appliances in the household *400 = kWh in the year.
