The graph below shows the demand for electricity in England during typical days in winter and summer. The pie chart shows how electricity is used in an average English home.
Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
Write at least 150 words.
The first chart shows that typical daily demand for electricity in England in winter and summer is quite different. According to the line graph, the demand for electricity during typical days is more than twice as much in winter as it is in summer, peaking at 45,000 units at 10 p.m. in winter while bottoming at 30,000 units at 8 a.m. On the other hand, in summer, the demand for electricity peaks at 20,000 units at 2 p.m. and bottoms at 15,000 units at 9 a.m. in a day. Overall, the bottoming demand in summer days and the peaking demand in summer evenings come one hour later than the corresponding figures in winter.
The pie chart shows that electricity is mainly used in 4 sectors in an average English home. Over a half of electricity (52.5%) is used for heating rooms or water, which can greatly explain why the electricity use is so high in winter. Another significant proportion of electricity (17.5%) is used by ovens, kettles and washing machines. The electricity used for lighting, TV and radio is at 15%, which is matched by the electricity used by vacuum cleaners, food mixers and electric tools.
