Model answer

The table provides a comparative breakdown of household energy consumption across five categories in City A and City B in 2010 and 2020.

Overall, it is readily apparent that heating consistently comprised the dominant share of domestic demand in both cities, whereas lighting constituted the lowest proportion. Furthermore, while the share used for heating declined, the share allocated to electronics rose noticeably over the ten-year period.

In 2010, heating represented 48% of household energy use in City A, which was considerably higher than City B at 35%. Although both figures fell to 40% and 32% respectively by 2020, heating remained the single largest category. Conversely, electronics demonstrated the most substantial growth, climbing from 12% to 19% in City A and from 15% to 23% in City B.

In terms of the remaining uses, water heating remained relatively stable, accounting for 24% to 25% in City A and 28% to 27% in City B. Cooking changed only slightly, rising from 10% to 11% in City A and falling from 14% to 12% in City B, while lighting diminished slightly to 5% and 6% by 2020.
