The graph illustrates the production levels of petroleum, coal, and natural gas in the UK from 1981 to 2000.
Overall, the highest production level was recorded by petroleum during this period; however, natural gas also showed a consistent increase in production. In contrast, coal production exhibited a declining trend.
In 1981, natural gas production was below 40 million tonnes. It then witnessed a rising trend, reaching 100 million tonnes in 2000, making it the second most utilized fuel in the UK. Although petroleum production was at 90 million tonnes in 1981, it rose to 140 million tonnes and remained stable from 1984 to 1987. The production level declined to a minimum of 100 million tonnes after matching the energy units of 1984.
Coal production in the UK was at 80 million tonnes in 1981, but it dropped to below 40 million tonnes before reaching a plateau from 1981 to 1983. The production gradually decreased from 60 to 30 million tonnes between 1986 and 2000, respectively. As a result, coal production ranked third on the graph.
