The graph illustrates the production levels of the main fuels in the UK, including Petroleum, Coal, and Natural Gas, over a period from 1981 to 2000. The production is measured in units.
Overall, the production of Petroleum experienced fluctuations but remained the highest throughout most of the period. Meanwhile, Natural Gas showed a significat increase, eventually surpassing Coal, which steadily declined.
In detail, Petroleum production beagn at about 100 energy units in 1981 and rose sharply to peak at 140 units by around 1986. After this peak, it dropped significantly to just below 100 units by 1992 before recovering slightly towards the end of the period, stabilizing at aroung 130 units in 2000.
On the other hand, Coal production started at approximately 80 units in 1981 but witnessed a graduate decline over the years. By 1991, it had fallen to about 60 units , and this downward trend continued, reached a low of approximately 40 units by 2000.
Natural gas had a different trajectory, begining with a low production level of around 20 units in 1981. However, its production rose steadily, surpassing Coal around 1995 and continuingto increase, reaching nearly 100 units by 2000.
