The line chart illustrates the levels of three fuels produced in the United Kingdom in the period from 1981 to 2000.
Overall, it can be seen from the graph that the UK had a tendency to manufacture more petroleum and coal. Additionally, petroleum was the most mosthighest most highest fuel produced in this country through the period of given time.
In 1981, starting at about 90 million tons, petroleum got the first position of three fuels, followed by coal with 80 MT, and the last position belonged to natural gas with approximately 38MT. In the period of six years, ending in 1987, petroleum level of production witnessed an increase and remained stable at approximately 140MT. In the next two years, its production saw a dramatic decrease to 100 MT before recovering and rising up to roughly 142 MT in 2000. Natural gas, from 1981 to 1991, saw a slight increase in the range 40 to 50MT. After that, it was produced significantly to reach nearly 100MT at the end of the period.
In contrast, coal experienced an exponential fall to hit the lowest point at about 30MT in the first three years, ending in 1983. After this substantial fall, coal production rose up to 60MT in 1986 and fell down to roughly 38MT in 2000, being the least pollution producing fuel in the UK.
