The graph illustrates the different kinds of fuels produced by the UK from 1981 to the year 2000. Overall, the UK produced three types of fuel. Natural gas production surged drastically, petroleum production also increased, while coal production dropped.
In 1981, Natural Gas production was around 40 million tonnes, with very little growth until 1991. After 1991, gas production increased significantly, reaching 100 million tonnes by the year 2000.
Petroleum production was around 90 million tonnes in 1981. By 1983, it had reached 140 million tonnes and remained constant for the next four years. However, it started declining from 1987. In 1989, production dropped to 100 million tonnes, remaining stagnant for the next couple of years. It began rising again by 1992, reaching 140 million tonnes by the year 2000.
Coal was the only product that saw a decline, dropping below 50% from 1981 to 2000.
