The graph illustrates the typical daily demand for electricity in England during both winter and summer, while the accompanying pie chart delineates the allocation of electricity usage in an average English home.
Overall, it is evident that there are distinct patterns in electricity demand between the two seasons, with winter exhibiting more fluctuation compared to the relative stability seen in summer. On the second graph, it is apparent that the majority of electricity is consumed for heating purposes, followed by household appliances and lighting/electronics.
During winter, electricity demand experiences notable fluctuations throughout the day, with peaks occurring in the early morning and evening hours, reaching a maximum of 50,000 units at 21:00 and dropping to 35,000 units by midnight. In contrast, summer demand remains relatively stable, hovering around 17,000 to 20,000 units throughout the day, with minor fluctuations during peak usage periods.
In terms of electricity usage in English homes, heating rooms and water consume the largest share at 52.5%, followed by appliances such as ovens, kettles, and washing machines at 17.5%. Lighting, TV, and radio collectively account for 15.0% of usage, while household appliances like vacuum cleaners and food mixers, along with electric tools, make up the remaining 15.0%.
