The line graph depicts information about manufacturing levels of the petroleum, coal and natural gas in the period of 1981 to 2000 in the UK.
Overall, in all seasons petroleum usage was in big demand despite a slight fluctuation. While, other two fossil fuels remain unchanged in overall, however,natural gas production levels showed a significant increase.
First of all, the enegy unit of petroleum was around 90 in 1981, and production level gradually went up to 140 energy units in 1984. Secondly, the manufacturing level of petroleum after remainings unchanged between 1984 and 1987 sharply dropped off to equally 100 energy units from 1990 to 1992. Following that, the trend experienced a sudden increase to 120 units in 1993 and 140 energy units in 1995, respectively. Lastly, the production of petroleum in UK ranked a high level and remained stabile before 2000.
Furthermore, in 1981 the energy level of natural gas reached 40 units and coal 80units before 1983, respectively. However, the coal creation experienced a quick decrease to 39 energy units in 1984.Whilst, a natural gas levels showed a long-period 40 energy units in 1984 and 1991. Moreover, in this 1991 intersects in one level coal with a marginal plummet under 40 units.Meanwhile, production levels of eco-gas climbed to 80 units in 1996 and 100 units by the year 2000, respectively.
