The first chart illustrates the units of electricity usage over a typical day in two seasons, winter and summer, while the second chart presents the proportion of the four main uses of electricity (heating rooms and heating water, ovens, kettles, washing machines, lighting, TV, radio and vacuum cleaners, food mixers and electric tools).
Overall, it is clear that electricity demand was considerably higher in winter than in summer throughout the day, with both seasons reaching their highest levels in the evening. Additionally, more than half of the electricity was used for heating rooms and water, making it the largest proportion.
Turning to the line graph, at the beginning of the day, electricity demand in winter stood at approximately 35,000 units, compared with about 18,000 units in summer. The figure for winter then rose sharply to a peak of around 40,000 units at 9:00 before dropping to roughly 30,000 units by midday. By contrast, electricity demand in summer fell slightly to about 15,000 units at 9:00 and then recovered to around 20,000 units at 12:00.
As for the pie chart, heating water and rooms accounted for the largest share of electricity consumption, making up 52.5% of the total. Ovens, kettles and washing machines represented the second largest percentage, at 17.5%. By comparison, both the category of lighting, TV, radio and vacuum cleaners, food mixers, electric tools showed similar patterns, measuring 15.0% of overall electricity use.
