The line charts illustrate how much energy was produced from three types of fuel in the UK commencing in 19 years, beginning in 1981.
Overall, there was an increase in the amount of energy coming from petroleum and natural gas, while a significant decrease was seen in the production of coal . In addition, petroleum showed the highest figure throughout the period.
Petroleum energy started at about 90 million tonnes (MT) , after which it experienced a dramatic rise to 140 MT in 1986, before declining to exactly 100 MT in 1991. Besides, a slight increase of natural gas production can be seen between 1981 and 1991, from 40 MT to about 45 MT. Another point worth noting is that the figure for coal was at 80 MT in 1981 followed by a significant decrease to under 60 MT in 1991.
Data from petroleum showed a continuous rise during the next period, reaching 140 MT in 2000. The figure for natural gas saw similar changes, ending the period at 100 MT. Conversely, the British tended to use less coal power , which finally declined to under 40 MT in 2000.
