IELTS Writing Task 1 Bar Chart

Model Answer

The bar chart compares the energy consumption and expense of operating 16 different items of household equipment. Overall, we can see significant differences in both cost and consumption.

To begin with, there are some common household items which consume relatively little energy. These include an electric blanket (approx. $10 or 100kwh/year), a microwave oven (approx. $15 or 150kwh/year) and a television (approx. $17 or 170kwh/year).

By contrast, devices that might be classified as ‘luxury’ items such as a pool pump or spa are comparatively expensive and energy-intensive, at nearly $125 or 1500kwh/year and around $190 or 2225kwh/year respectively.

It is interesting to note that even among household items normally considered alike, such as a microwave and refrigerator, there are enormous discrepancies in cost and energy use. The former uses only around $15 or 150kwh/year, while the latter consumes at least six times that amount at $90 or 1150kwh/year.

In conclusion, it appears that there is no clear pattern in the relative energy consumption of domestic equipment, although households had better be aware of the high running costs of luxury items such as a pool pump and spa.
