Band 6+: The graph below shows the production levels of the main kinds of fuel in the UK between 1981 and 2000. Summarise the information by selecting and reporting the main features, and make comparison where relevant.

The given line graph delineates the production levels of the various aspects of fuel in the UK over a 20-year period from 1981 to 2000.

Overall, it is clear that petroleum stayed the highest proportion of all time. Moreover, the percentage of coal decreased, while natural gas increased over 20 years.

In 1881, petroleum stayed at the highest point, accounting for nearly 100 tons. Meanwhile, in that time, coal and natural gas are not likely to be used, making up 80 in coal and 40 in natural gas. In the next 4 years, the number of coal decreased significantly to 40, while petroleum rocketed to 140 and natural gas remained unchanged.

In 1986, petrol still stayed at the highest point whilst it witnessed a noticeable decrease by 40. Moreover, coal and natural gas increased slightly to 60 and 50 respectively. From 1986 to 2000, petrol saw fluctuations and touched a peak at 145. On the other hand, coal decreased slightly over 5 years then stopped at 40. By contrast, natural gas had a remarkable increase, accounting for 100.
