The graph illustrates the variation in electricity demand between winter and summer in England for different hours of a day, while the pie chart depicts the primary sources of electricity consumption in typical English household.
Overall, the consumption of electricity in winter is significantly higher than in summer at all times of the day, peaking in the evenings after 9 pm. Regarding the consumption categories, space and water heating prevail, accounting for slightly more than half of all energy consumed.
It can be seen that the consumption of energy in winter is considerably higher than during summer. Initially, at midnight, usage is approximately 35,000 units in winter and 18,000 units in summer. However, demand fluctuates dramatically in winter, plunging in the early morning to nearly 30,000 units around 7 am, and rising steeply to 40,000 by 1 pm before soaring to 48,000 units after 9 pm. Similarly, summer usage increases between 9 am and 2 pm to 20,000 units, and surges at 11 pm to nearly 19,000 units.
According to the pie chart, more than half of the electricity consumed is used for water and space heating, accounting for 52.5 percent. Ovens, kettles, and washing machines account for the second-largest share of electricity consumption, with 17.5% of the total energy consumed. Vacuum cleaners, food mixers, and other electrical appliances make up 15% of electricity consumption, the same proportion as lighting, television, and radio.
