Sample Answer 1:

The given graphs show the electricity demand in England in a typical day of winter and summer and also show how people used this electricity. According to the first line graph, we can see that the electricity demand in winter is much higher than the demand in summer in England.

In a typical day, the electricity demand in winter season is around 35000 units and it is around 18000 units in the summer season. Again the demand for the electricity varies on several hours of the day and the demand from 6:00 to 9:00 am is lesser than the demand in other hours of the day. During the winter the demand is highest from 21:00 to 23:00 and during summer the demand is highest from 13:00 to 14:00 hours.

Based on the pie chart we can infer that the room heating and water heating is the main purpose people consume the electricity in England. The demand for washing machine, kettle and ovens consume around 18% of total electricity consumed and two other categories consume 15% electricity each. These two other categories which consume 30% of total electricity include light, TV, Radio, vacuum cleaner, food mixer and other electric told and devices.

Model Answer 2:

The presented graph illustrates the electricity requisition in England during two different seasons, winter and summer. Meanwhile, the pie chart demonstrates how the electricity is utilised daily and to what quantity.

In general, both in winter and summer, the electricity demand rises up from around 9:00 am to about 23:00 pm and the electricity in mainly spent for heating room and water.

Looking at the detail, the electricity demand in summer is reckoned between 10,000 – 20,000 units. It goes to around 12,000 before 9 am and slightly increases to around 20,000 at 14 pm and relatively fluctuates until the rest of the day. However, in winter, the electricity requisition sets about 35,000 units at 00 am and gradually spikes before it actually rises at 9 am and keeps the level swells until around 45,000 units at 23 pm.  

Meanwhile, due to utilisation and quantity, heating room and water require the vast majority, 52%, of electricity using. This high proportion is related to the high electricity demand for these two appliances during winter. Whereas other kitchen and electronic devices, vacuum cleaners, food mixers and electronic tools amass lower proportion, 48%, than heating rooms and water.
