The line graph compares the production of three types of fuel between 1981 and 2000 in UK.
Overall, it’s noticeable that the coal had lost it’s value significantly over the period of 19 years compared to the other 2 species. The petroleum and natural gas, at the same time, flectuated slightly.
At the beginning of the period, the coal industry had the highest level of production. In 1981 it stood at 130 million tonnes, which was comparatively higher than 90 million tonnes of petroleum and 70 boms of natural gas indicators. Over the next few years, in 1984, the average number of coal production dramatically dropped to 50 million tonnes. In contrast, natural gas reserves have risen to its maximum by 1990. Besides, the the amount of natural gas and gasoline has levelled off in 1985 and 1995. Petroleum, in turn, has changed its values from only 100 million tonnes to 80 in 19 years. However, it peaked at the end of the period compared to the coal and gas.
