The line graph elucidates the level of production of the fuels in the United Kingdom between the period of 1981 to 2000. Overall, it can be seen that all three kinds of fuels had a different trend during the period reported. Natural gas had an increasing trend, while coal had a decreasing trend, and petroleum had an irregular movement.
In detail, The UK produced natural gas from 1981 to 1990 for just approximately 40 million tonnes of oil. But then, it is reported that starting in 1991, the production soared dramatically to double in just 5 years, in 1996 for 80 million tonnes and continue to rise until 100 tonnes in 2000. On the other hand, in 1981 – 1983, coal production was 80 million tonnes, and then plunged to half, below 40 million tonnes in 1984. Even though in 1985 the production was stepping up, however, the production began to drop again slowly to nearly 30 million in 2000. Finally, petroleum was the one with a fluctuating trend. Nonetheless, it produced 90 million tonnes in 1981, which was the highest compared to other fuels, and ended up with 140 million tonnes in 2000 which is also the highest among other fuels production.
To wrap up, the UK’s main fuels production levels are mainly petroleum with an unprecedented trend, followed by natural gas which has an increasing trend, and coal was the lowest production level which also has a decreasing trend.
