The graph illustrates the production rates of three primary fuel types in the UK from 1981 to 2000. It is evident that Petroleum has been the prominent choice of fuel usage in the UK throughout the years.
The usage of fuel energies was at its lowest point in 1981, with natural gas being used the least with 40 units, and coal and petroleum taking the lead with 80 and almost 100 units of energy respectively. Moreover, we can observe a significant increase in petroleum usage in 1986 with 140 energy unit ,while, the use of natural gas as means of fuel remained relatively the same in 1986 through 1991 with 41 energy points. Contrary, the coal production levels dipped significantly in 1986 with 40 energy units and displayed stability in 1991 with approximately 60 energy points. Additionally, the coal-producing levels saw a downward trajectory from that year, reaching at its lowest point in 2000 with 35 units.
Overall, the manufacturing of petroleum experienced a slight dip in 1991, and then showed an uptrend and took the lead till 2000 with 140 energy units. Similarly, the production rates picked up pace from 1992 through 2000 with 100 units, as the second leading prominent energy manufacturer in the UK.
