The line graph illustrates the production output of petroleum, coal, and natural gas in the UK over a 20-year period commencing in 1981.
Overall, the UK consistently produced more petroleum compared to the other fuel types during the depicted period. While petroleum and coal production experienced fluctuations, natural gas yield witnessed a negligible increase.
Among the three kinds of fuel, the production level of petroleum consistently led the way. Its figure started at roughly 100 tonnes, rose to about 130 tonnes in the two ensuing years, stayed unchanged till 1987 before dropping back to the initial level in around 1988. After a trivial fall, the amount of petroleum generated in the UK rebounded to its peak of 130 tonnes in 1996 and then marginally descended to approximately 120 tonnes by the conclusion of the period.
In 1981, coal production in the UK was 80 tonnes, double the output of natural gas. Despite fluctuations in the initial six years, coal production decreased to slightly under 40 tonnes by the end of the period. Concurrently, natural gas production remained stable from 1981 to 1994, and then ascended to surpass coal’s figure since 1997, reaching the second rank in 2000 with over 80 tonnes produced.
