The line graph illustrates how the production levels of the main kind of fuel in the UK changed from 1981 to 2000.
In general, the production levels of natural gas and petroleum increased, while the figure for coal in the UK decreased over 21 years. The production level of petroleum was higher than that of natural gas and coal for most of the years.
In 1981, the figure for petroleum in the UK stood at 90 energy until, which was higher than the figure for coal and natural gas, at exactly 80 and around 40 energy until respectively.
In 1985, the production level of coal in the UK decreased significantly to around 40 energy until and increased dramatically to about 61 energy until 1986. Similarly, the figures for petroleum in the UK increased slightly to exactly 14o energy until. In contrast, the production of natural gas increased slightly to around 40 energy until, 1986.
From 1986 onwards, the production level of petroleum reached a peak of precisely 140 energy until, and the production of natural gas increased sharply to around 100 energy until in the final years. the final years. In 1986, the figure for coal in the UK declined remarkably to roughly 39 energy until at the end of the given period.
