AVERAGE ENERGY CONSUMPTION PER FAMILY To calculate the daily power consumption of our families and to obtain truthful data, we have computed the average cosumption over 6 days after having read our electricity meters. ESTIMATED AVERAGE DAILY CONSUMPTION 7,8KWH ESTIMATED AVERAGE WEEKLY CONSUMPTION 55KWH ESTIMATED AVERAGE YEARLY CONSUMPTION 2870KWH ACTUAL AVERAGE DAILY CONSUMPTION 8,5KWH

OBSERVATIONS We have noticed that the estimated consumption is inferior to the real one, this because one of us has more appliances than the average.
