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

The graph illustrates how much three different kinds of fuel namely petroleum, coal and natural gas produced in the UK from 1981 to 2000. The units are given in tons.

Overall

, what stands out from the chart is that there was a dramatic increase in petroleum and natural gas,

while

the opposite was true with coal.

In addition

, the highest data was recorded in coal manufacture from 1981 onwards. Looking at the figures in

further

detail, it can be observed that the data for petroleum started at over 90, after which it increased to nearly 140 in 1984 before fluctuating gradually and ending the period at approximately 142.

Additionally

, the production of natural gas was at around 39 in 1981,

then

experiencing an upward trend to exactly 100 throughout 2 decades. Turning to the remaining statistics, it can be noticed that in the first 5 years, the making levels of coal saw a significant fluctuation, reaching about 50

at the end

of 1985.

However

, it remained unchanged at

this

point for 3 years later, before fluctuating slightly and witnessing under 38 in 2000.
