The graph below shows the production levels of the main kinds of fuel in the UK between 1981 and 2000. Summarize the formation by selecting and reporting the main features and make comparisons where relevant.

The provided line graph depicts the rates of fuel

production

in the UK over the period from 1981 to 2000. The graph outlines the

production

proportions of petroleum, coal, and natural

gas

, measured in energy

units

(where 1 energy unit equals 1 million tonnes of oil) In general,

production

of natural

gas

increased throughout the 19-year period,

whereas

coal manufacturing showed a totally different trend. To start with, Petroleum consistently maintained the highest

production

levels throughout the entire period, surpassing coal and natural

gas

. Its trend illustrated graduate growth from 100 to 140

production

was stable but witnessed a significant decline from 80 to 40 energy

before gradually increasing and stabilizing by 1986.

On the other hand

started with a lower level of
