the graph below shows the production levels of the main kinds of fuel in the UK between 1981 and 2000. Summarize the information and write 150 words.

The line chart provides key information about the levels of

production

of the essential sources of fuel in the United Kingdom from 1981 to 2000, with units measured in energy units.

Overall

, it can be seen that the level of

production

of petroleum remained the highest one compared to the other sources over the given period.

In addition

, natural

gas

production

was nearly steady until about 1989,

whereas

it began to rise rapidly, in around 1990.

According to

what is shown, in 1981, the amount of petroleum was about 85, which was the biggest quantity,

then

it increased rapidly until it reached 140, in 1984. After that, it remained steady at around the same quantity from 1984 to 1987. It experienced a drop to about 100, in 1990. Following that, it rose again until it reached above 140, in 2000. In terms of coal and natural

gas

, in 1981, the

production

of coal was, at about 80, which was twice the amount of natural

gas

.

Conversely

, in 2000, the

production

of natural

gas

jumped to approximately 100 to be more than double the amount of coal in the same year.
