The graph highlights data about the production levels of the main types of fuel (petroleum,coal, natural gas) in the UK over a 19-year period between 1981 and 2000. The production levels of the main types of fuel are measured in energy units.
Overall, what stands out from the graph is that coal halved,petroleum and natural gas felt a significant increase. Another interesting fact is that petroleum was the most popular fuel at the start and the end of the period. In addition the highest point of the graph is petroleum in 1999.
Looking at the details of the production levels of petroleum and natural gas.As regards, production levels of petroleum started at just over 80 in 1981, and it increased considerably to 140 in 1986.Despite declining remarkably to 100 in 1991, this figure then recovered to 140 in 2000. Regarding the production levels of natural gas started at 40 in 1981, and it doubled in 2000.
As regards the production levels of coal . It started at 80 in 1981, and it was stable until 1983. Having halved in 1984, this number then recovered to 60 in 1986. After that, this figure decreased dramatically to just under 40 in 2000.
