The graph shows the production rates of three main types of fuel in the UK from 1981 to 2000. Overall, petroleum was the most popular fuel choice during this time.
In 1981, natural gas was the least used fuel, producing 40 units. In comparison, coal produced 80 units, and petroleum was the highest at nearly 100 units. By 1986, petroleum production rose significantly to 140 units, while natural gas stayed stable at around 40 units. Coal production dropped to 40 units in 1986 but then stabilized at about 60 units in 1991.
From 1991 onwards, coal production continued to decline, reaching its lowest point of 35 units by 2000. Petroleum had a small decrease in 1991 but then increased again, remaining the top fuel with 140 units by 2000. Natural gas production started to rise gradually from 1992, reaching 100 units by the end of the period, making it the second most produced fuel.
In summary, petroleum kept the highest production levels throughout these years, natural gas grew steadily, and coal production fell significantly.
