Band 4+: 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 line graph depicts the production quantities of 3 energy sources in the UK throughout a period 19 years.

Overall, production levels of petroleum produced was the highest. The creation levels of natural gas and petroleum were upward trend, while the coal was declining pattern.

In detail, the creation of petroleum was produced 10 tons more than coal, at 80 tons, whereas the natural gas produced corresponding to half of the coal in 1981. Furthermore, the quantity of petroleum produced in 1986 increased significantly to 14 tons, which bottomed out in 1991. In comparison, the amount of coal produced dropped dramatically to 37 tons in 1984 and then marginally increased to 60 tons in 1986.

Conversely, in 1991, the amount of manufactured petroleum increased significantly to 100 tons. Additionally, the amount of natural gas increased significantly to 100 tons in 2020. Moreover, there was an increase in the quantity of petroleum, which peaked at 142 tons at that time. In contrast, the amount of coal decreased dramatically, reaching a low of 38 tons in 2000.
