The line graph illustrates the main types of fuel used in England during 1981 and 2000.
Overall, petroleum is the greatest fuel that has been used for over two decades. While coal and natural gas’s growth below as the second and the third energy in the first period of 1981 to 1991, respectively.
One noticeable feature of the data is that petroleum has increased in the peak time almost 5 years since 1983, approximately 140 tonnes, and also still remained the highest fuel being used, even slightly dropping until 1992.
However, in the former, it rose back to the best position after 1995. On the other hand, coal has decreased to around 40 million tonnes in 1984. Whilst, natural gas collapsed from steady movement to the second range near 1991, afterwards, strongly moving up. In contrast, coal has fallen continually behind the year that natural gas broke up.
Lastly, only two main fuels, petroleum and natural gas, are being used the most, especially since starting in 1991.
