The graph illustrates the information about the production levels of certain fuels in the Uk between 1981 and 2000 respectively.
Overall,it is seen that the production of fuel has fluctuated in the years and the production of natural gas has experienced an upward trend where coal had a massive breakdown through the years.
Among three,the making of petroleum in the year 1981 was nearly 100 units which increased and reached exactly 140 engergy units in the year 1986.Similarly,after the rise in the year 1986 it experienced a huge decrease in the year 1991.After that the production of petroleum again went up to 140 units in 2000.
The manufacturing of natural gas was 40 units in the year 1981 to 1991.Later on the manufacturing level was increased and the production of natural gas increased at a constant level and reached approximately 100 units in 2000.Likewise,the production level of coal had a huge decrement which reached nearly 20 units from 80 units in the year 2000.Out of all,the production level of natural gas experienced a flow of increment among the years.
