You should spend about 20 minutes on this task. The graph below shows the production levels of the main kinds of fuel in the UK between 1981 and 2000. Summarize the formation by selecting and reporting the main features and make comparisons where relevant. You should write at least 150 words.

The diagram illustrates the alteration over the 19-year intervals of 1981 of manufacturing levels of the 3 dominant varieties of

fuels

in the UK.

Overall

,

while

most kinds of propellant oscillated strongly over the years, most of them generally increased and were higher than the 1981 produced amount of Energy Units - abbreviated as

EU

. There were

also

certain shifts in the rankings of their production level On the one hand, Petroleum and Natural Gas

Fuels

seem to augment the initial amount.

Initially

,

While

Petroleum

fuels

started with roughly 90

EU

, it reached its summit between 1984 and 1987 with 140

EU

but went back to 100

EU

in 1991, but from 1992, it steadily increased and back to 140

EU

in 2000. Interestingly, despite the fluctuation, Petroleum still dominated the rest as being the most-produced energy unit for 19 years.

Furthermore

, Natural gas, despite plateauing at 40

EU

for 10 years, started to stably increase in 1991 to 100

EU

in 2000

while

exceeding Coal

fuels

in 1991 as being the second-most produced fuel.

On the other hand

, Coal energy decreased significantly from the started produced amount at 80

EU

in 1981, decreasing to 40

EU

in 1984 and going back and plateauing between 1986 and 1991 at 60

EU

until constantly decreasing to less than 40

EU

in 2000, staying as the third-most produced

fuels

.
