Studying the number of Electrical appliances and time using electricity during 1920 and 2019
. We got a two charts that explains the percentage of households with electrical appliances, and the time of doing houseworks during each week.
First of all, The first chart introduces the percent of households they’ve an electrical appliances in their houses, So we can see that Washing machines have increased from 40% to 75% during 99 years, Refrigerators had an incredible rising from 0 to 100%, and Vacuum cleaners using had increased from 30% to 100%, what we can say after these results that the improving technology of factories plays an essential role in this growth.
On the other hand, we can know from the chart below that while the electrical machines had been rised the time of using electricity had been decreased from 50 hours per week to 10 hours per week, because of that I think that the general improvement of technology and involving AI models with inverter systems leads to increase the efficiency of these machines, So probably that’s what leads us to reduce the time of using electricity.
The conclusion, As much as we know and improving our systems, as much as we turn this life easier.
