The construction of positions in the main categories of energy source in the UK is illustrated by the given line graph in two various years.
Overall, the production levels of the main types of energy fluctuated significantly for all categories apart from natural gas over the given period.
Statistically, the quantity of manufacture to the petroleum went up gradually from 92 in 1981 to 140 in 1986, rising further more dramatically to stead steeply of 140 in 1986. By contrast, this figure went down to approximately 100 in 1991. Although, this construction after 1991 years of steady rise from 100 to 103 sharply , this index started to increase to 140 in 200. Similarly, the production of the Coal increase significantly from 80 than declining further to 38 slightly in 1986. Analogously, after 1986 year of fluctuations was around 50 in 1995 then rose rapidly to about 41. Likewise, decreased moderately to nearly 30. In the some way, after 3years of steady rise from about 40 to 80 the amount at the natural gas rising further from 80 to 100 over the given period.
