The provided line chart illustrates the data about the electricity requirement during typical winter and summer days in England, while the remaining pie chart shows the proportion of electric usage’s purposes in a particular English household.
It is clear that, in the line graph, the typical daily electric demand in winter is significantly higher than that in summer. Additionally, the electricity used for heating rooms and water is the biggest contributer to the electricity usage witnessed in the pie chart.
As can be seen in the line graph, at the beginning of day, the typical electricity demand in winter and summer commence at 35000 units of electricity and 18000 units of electricity being twofold the former figure, respectively. By 9 hours after, the electricity consumption in both winter and summer dramatically increase until 14 hours, with the former’s figure accounting for 40000 units and the later’s one standing at 20000 units. Especially, at 21 o’clock, the electric requirement in winter reaches a peak of highly over 40000 units before witnessing a sudden decrease to the beginning point of 35000 units by the end of the day. Moving to the counterpart, the requirement for electricity in summer seemingly stays unchanged from approximately 15000 units at15 o’clock to modest 16000 at 21 o’clock before going down to the same figure in the commencement – 18000 units.
Regarding the purposes for electric usage, the heating room and water purpose accounts the highest proportion, contributing 52,5 % holding more than half of the total. Otherwise, the electricity utilized for ovens, kettles and washing machines is apparently modest, with its figure takes up just 17,5%. The remaining lighting, TV , radio and vaccum cleaners, food mixers, electric tools purposes share the same percentage, making up each 15%.
