According to the line chart and pie chart given, which illustrates information concerning the changes in the amount of electricity used in an English home during summer and winter over the 24 hours and how they are used for four purposes including heating rooms and water and small and tools, we can see that the amount of electricity used in the winter is significantly higher than that of the summer.
Electricity consumption peaks around 40,000 units during the winter just before 3 AM, while in the summer it gradually declined in the first 9 hours from mid-night. Between 9 o’clock in the morning and just before 3 PM, electricity consumed in both the summer and winter increased significantly and then went into a period of stabilization. There is a peak between 9PM and mid-night in both summer and winter; however, the peak in the winter is significantly higher and is approximately 1 hour earlier than that in the summer.
As seen in the below pie chart, the majority of electricity is used for heating rooms and water (52.5%), followed by that used in powering ovens, kettles and washing machines(17.5%), then by power used for lighting, TV and radio is 15%, which is equivalent to that used for vacuum machines, food mixers and electric tools.
