The line graph demonstrates the production levels of main fuels in England within nineteen years of period between 1981 to 2000.
Overall, the fuels has reached its peak in production except the coal, which can be seen dramatically decreased. The crucial fact that can be noticed, is that petrolium never gave up the leading position in sellings.
Although there was a good trend for the leading seller from 1981 till 1987 years, with reaching a stable 140 millioin of tonnes, it dramatically decreased due to an economic crisis. It’s unbeatable that revolution in 1990s has made the situation much better with sales rising until reaching its peak of 150 million of tonnes.
The second lead, natural gas, was almost in bankrupt position with sales as low as 40 million tonnes, however the revolution affected the production in positive way with sales reaching the point of almost 100 million od tonnes in 2000. In contast, the coal production seemed to be functioning mych better before the revolution with its dramtic decline form 80 million of tonnes to 40 million of tonnes. The twice of difference can be explained by elaborating the train improvement, with no need of coal in use, it lost its value.
