IELTS 4 Test 2 Task 1

The line graph illustrates the movements in electricity demand in England over a 24 hour-period on a average winter’s and summer’s day. The pie chart gives information on the proportion of electricity consumed by various categories of appliance within a typical English household.

From the line graph, it can be clearly seen that the demand at any time of the day in winter is approximately twice as high as that in summer. The pie chart highlights the fact that over half of all the electricity used for domestic purposes is for heaters of rooms and water.

At the very beginning of a typical winter’s day (midnight), England’s electricity demand begins to rise rapidly from its second lowest level of the day (35,000 units) to almost 40,000 units within 3 hours, after which point, it falls just as quickly to its lowest level of the day at a little over 30,000 by 7:30am. Unlike winter, summer sees its demand slide gradually without fluctuation from 17,000 units at midnight to its lowest daily level at slightly later in the morning (13,000 units at 9am).

As previously mentioned, heating of rooms and water was the highest contributor to electricity consumption (52.5%). The remainder was divided almost evenly between the other three appliance categories: Ovens, kettles, washing machines (17.5%); Lighting, TV, and radio (15%); and Vacuum cleaners, food mixers, and electric tools (also 15%).
