The rendered linegraph represents the manufacturing levels of the distant fuel types involving coal,petroleum and natural gas from 1981 to 2000.
Taking a closer look over the given details, it can be witnessed that the production of the petroleum was maximum in 1986, observed as 140 energy units. Along with that the production level of coal was highest in 1981, traced as 80 energy units. In stark contrast. the natural gases production was at peak noed as 100 energy units, during the year between 1996 and 2000.
Moreover the level of petroleum was alike in 1996 at 140 energy units. Moreover, there is a discrepancy of 40 energy units between coal and natural gas during the year 2000. During the year 1991, the units of the coal was twice the value of petroleum during the same year.
Overall, the petroleum and natural gasses had observed a inclining trend, whereas the coal was lagging behind them.
