The above given line graph illustrates the manufacturing of non-renewable energy resources in the United Kingdom by the year of 1981 till 2000.
As we can see, the production of petroleum is in increasing trend through out the years as compared to other resources. Although in 1991 its production decreases from 140 to 100 energy units but again its started increasing. On the other hand, the natural gas manufacturing was in steady position from 1981 to 1991 and after that its level increases from 40 energy units to 100 energy units by the year of 2000.
At last the coal generation shows a descend trend, in starting it was higher in production than natural gas but as passing years its manufacturing decreased from 80 to 35 energy units.
Overall, the pertroleum was on the top and after that natural gas and in the last coal manufacturing in UK from 1981 to 2000.
