The line graph below describes production of different fuels in the UK from 1981 to 2001. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The line graph gives information about the production of coal, gas and petroleum in the UK from 1981 to 2001. It is clear from the graph that there was a decline in the production of all three types of fuel over the given time period, especially coal.

To begin

, coal started out with the highest value of 127

million

tonnes

produced in 1981, and

then

plummeted to 51

million

tonnes

in 1984.

Thereafter

, the ratio recovered significantly to 106

million

tonnes

in 1986. From

then

onwards, the ratio has been consistently declining and eventually reached a low of 35

million

tonnes

in 2001. The manufacturing of petroleum showed a slight increase from 96 to 100

million

tonnes

at the very start of the period. From 1983, there was a gradual decrease in production to a low of 79

million

tonnes

in 1989. Later on, from 1991 to 2001 the numbers remained relatively stable, between 80 to 87

million

tonnes

. Natural gas manufacturing started at 72 bem and increased for almost 10 years, reaching a high of 113 bem in 1990. That point marked the start of the gradual decline of around 5 bem per year, to the low of 67 in 1999.

Thereafter

, there was a slight recovery to 72 cm in 2001.
