The graph below shows the production levels of the main kinds of fuel in the UK between 1981 and 2000. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The line graph represents the level of production of three main fuels in the UK (

Petroleum

, Natural gas, and Coal) over a period of 19

years

from 1981 to 2000. Units are measured in

million

tonnes

.

Overall

, it is obvious that

figures

for

Petroleum

and Natural gas increased during the given period,

while

for Coal, it decreased.

In addition

,

Petroleum

was the main fuel in the UK throughout. As can be seen, the

figures

for Natural gas stood at around 40

million

tonnes

in 1981 and it was approximately the same for the next 8

years

before increasing sharply to a little bit more than 100

tonnes

in 2000.

Likewise

, the production of

Petroleum

climbed from under 100 in the first year to 140

million

tonnes

in 1986. after which the

figures

dropped from 140 to around 100

million

tonnes

in the next two

years

before reaching the highest point again at roughly 140

million

tonnes

in 2000.

On the other hand

, the production of Coal witnessed a sharp decrease in the first five

years

from 80

million

tonnes

to half. In 1986, the

figures

rose to more or less than 60

million

tonnes

and fluctuated for the rest of the period to reach the lowest point at around 35

million

tonnes

in the

last

year.
