IELTS Writing Task 1: Question
Bar charts often appear very simple but they can also contain a lot of information. It’s up to you to decide which information from the bar chart is important enough to go in your answer.
The bar chart shows the relative electricity consumption and cost per year of various household devices.
Write a 150-word report for a university lecturer explaining the data and making comparisons where relevant.
IELTS Writing Task 1: 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.

Why does this Task 1 answer get an IELTS Band 9 score?
Task achievement: The model answer presents an overall description first, followed by key supporting details that illustrate the main trend.

Lexical resource: The language in the question is effectively paraphrased. Synonyms are introduced for key concepts such as electricity consumption > energy use and cost > expense. Some less-common words such as discrepancies and energy-intensive are used.
Grammatical range and accuracy: The model answer is free from grammatical errors. Sentences tend to consist of multiple clauses. Paragraphs contain a variety of sentence structures.
Don’t panic when you see a lot of things to write about in Task 1, as in the bar chart above. You won’t lose marks if you omit a few of the items in the bar chart from your answer. The most important thing is to identify two or three general patterns and write about these. General patterns could be similar items with similar results. It’s also good to note an exception. But remember, you don’t need to describe every single item in order to get a high score.

Here's my full answer for the 'phone calls' bar chart in this lesson:
The bar chart compares the amount of time spent by people in the UK on three different types of phone call between 1995 and 2002.
It is clear that calls made via local, fixed lines were the most popular type, in terms of overall usage, throughout the period shown. The lowest figures on the chart are for mobile calls, but this category also saw the most dramatic increase in user minutes.
In 1995, people in the UK used fixed lines for a total of just over 70 billion minutes for local calls, and about half of that amount of time for national or international calls. By contrast, mobile phones were only used for around 4 billion minutes. Over the following four years, the figures for all three types of phone call increased steadily.
By 1999, the amount of time spent on local calls using landlines had reached a peak at 90 billion minutes. Subsequently, the figure for this category fell, but the rise in the other two types of phone call continued. In 2002, the number of minutes of national / international landline calls passed 60 billion, while the figure for mobiles rose to around 45 billion minutes.
