The given graph illustrates the production level of the important types of fuel in the United kingdom between 1081 and 2000.
Overall, we can see the production level of natural gases has rose dramatically whereas, the production level of coal had fallen significantly and manufacturing level of petroleum remains the same.
The diagram reveals that in 1981, the manufacturing level of natural gas in UK was below 40 unit. Following year the level had a significant increase in its production level and after 1991 , the production level fo natural gas rose dramatically reaching about 102 units in 2000.
We can also see that in 1981, the production level of pertroleum was below 1000 unit which then had a rapid growth reaching 140 units and continued to increase in a constant trend upto 1986. After that it got declined and again starts to rose upward eraching 140 units and continued to move steadily upto 2000. The manufacturing level of coal in first year was about 80 units which then got a rapid decline between 1981 and 1986. After that the trend got significant increase reaching nearly 60 units and moved in a constant manner. After 1991, the level started to decline reaching avout 35 units in 2000.
