These two diagrams respectively illustrate daily electricity consumption in England in autumn and spring, and the four specific aspects of electricity in a common English family.
From the graph, apparently, the amount of electricity consumed in autumn was twice as much as that in spring. ln details, in autumn the number hit a trough at about 30,000 units at 9 o'clock while the peak at nearly 50,000 at 22 o'clock. Between 13 to 19 o'clock there was hardly any change in the amount of electricity and in the rest of the day it fluctuated. As for spring. the lowest number was 12,000 at similar 9 o'clock, but there were two similar high points at 20,000 at both 13, and 23 o'clock, though the latter is slightly less than the former. Furthermore, compared with that in autumn, the number remained stable between 16 and 22 o'clock. The pie chart unfolds the fact that the statistics in heating was more than half of the total demand whilst the rest three in other fields, such as ovens, lighting or vacuum cleaners took up similar percentages of 17.5%, 16% and 15%.
