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 line graph illustrates the production levels of the main fuels in the UK over the 20-year period from 1981 to 2000.

Moreover

,

this

data consists of three items, namely petroleum, coal, and natural gas.

Overall

, petroleum generally represented the highest quantity of energy use during

this

period.

On the other hand

, natural gas showed an upward trend, and coal presented a converse situation.

To begin

with, despite the fact that petroleum approximately fluctuated between 100 and 145 billion

tonnes

of

oil

,

this

consistently was higher than the other two fuels between the years 1981 and 2000.

Subsequently

,

this

item ultimately accounted for 140 billion

tonnes

of

oil

in 2000. Looking at the data on coal in detail,

this

initially

showed 80

million

tonnes

of

oil

in 1981,

then

plummeted to roughly 38

million

tonnes

in 1984.

Next,

this

surged to 60

million

tonnes

in 1986;

however

, it gradually decreased, eventually representing around 33

million

tonnes

in 2000. As for natural gas,

this

remained an unchanged trend (40

million

tonnes

) until 1990,

then

surged to 100

million

tonnes

of

oil

in 2000.
