The line graph illustartes how much does the UK manufratures produce three primary fuel types during ninteen year period from 1981 to 2001.
Overall, it is evident that pertroleum production was the highest fuel throughout the span, while coal and natural gas have experienced a lot fluctuations. suprisingly, natural gas increaded steadily increased, in the meantime, the amount of coal fell down gradually and reamined the lowest fuel production amongst them.
To begin with, the first five years, all three kinds of fuels had experienced a several fluctuating trends, while the only fuel type, which is coal had seen sudden decline at 40 energy units. Conversly, both petroleum and natural gas stared to grow, which reached approximately 141 energy units and 41 energy units.
Moreover, throughout the last decade, natuaral gas gradually grew up to 100 energy units, at the same time, pertoleum remianed in the same position as it had in the 1986. Which is 141 energy units. The coal production fell down to 20 energy units in the 2000.
