Band 9: 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 comparisons where relevant.

The provided line graph illustrates the production levels of three primary fuels in the United Kingdom from 1981 to 2000.

Overall, it is evident that petroleum consistently maintained the highest production levels throughout the two decades, while coal witnessed a marked decline, and natural gas experienced substantial growth.

In 1981, the production of petroleum stood at approximately 90 million tonnes, escalating sharply to a peak of 160 million tonnes in 1999. This upward trajectory was punctuated by a brief decline in the early 1990s, where production dipped to about 100 million tonnes in 1991. However, it rebounded vigorously towards the end of the period. Natural gas production displayed a more consistent increase, commencing at roughly 20 million tonnes in 1981 and surpassing coal production levels in 1991, ultimately concluding the period at 100 million tonnes.

In stark contrast, coal production in the UK experienced a significant downturn over the analyzed timeframe. Commencing at 80 million tonnes in 1981, coal output plummeted to 20 million tonnes by 2000, despite a transient recovery to 60 million tonnes in 1986. This persistent decline underscores a notable transition in the UK’s energy production landscape, evident in the fluctuating fortunes of the three fuel types.
