The line graph illustrates everyday use of electricity in two distant seasons, whereas the bar chart compares the purpose of electricity usage.
Overall, electricity consumption is consistently higher in winter than in summer throughout the day. In addition, more than half of the electricity is used for heating rooms and water, making it the largest category of household electricity consumption.
In winter, electricity demand starts at around 35000 units, and rises to 40000 at 3, before experiencing a slight fall to almost 30000 at 9 o’clock. By the afternoon, demand gradually increases by 10000 units. Before midnight, it hits an all-time high of 48000 units at 9 p.m, before dropping to roughly 34000by the end of the day. By contrast, electricity demand in summer remains much lower compared with winter. It begins at around 18000 units, keeps falling to approximately 14000 units till noon, and then rises gradually to 20000 units at 3 p.m. Thereafter, it decreases slightly, before reaching another peak of about 20000 units at night, followed by a slight decline at midnight.
In accordance with pie chart, 52.5% of household electricity is used for heating rooms and water. Ovens, kettles and washing machines account for 17.5%, while lightning, TV, radios and vacuum cleaners, food mixers and electric tools each make up less than a fifth of total electricity used.
