Band 4+: You should spend about 20 minutes on this task. The graph below shows the production levels of the main kinds of fuel in the UK between 1981 and 2000. Summarize the formation by selecting and reporting the main features and make comparisons where relevant. You should write at least 150 words.

This graph illustrates the finding process for the fuels ,including Petroleum and Coal and Natural gas, in the UK over a period of 20 years, and also depicts the information according to the energy unit.

Overall, it is easily to be informed from the shape that the production of Petroleum was the highset for the whole chosien years, while the other tybes were lower.

On closer examination, Petroleum in the fisrt five yearis was significantly increased until it reach 140 energy unit. Moreover we can see a strong decrease in the scale for the next five years. In contarct , the last 10 years the production was keeping raising until reached the maximam level again.

turning to the remaining statistics, the Coal level in the bigening was near to the Petroleum, but then it kept deacrease from 1983 to 1984 , then it spent approximatly 5 years incraesing, and after that return to the deacrising mood. However, Natural gas was slightly increase over the 20 years. Furthermore , the energy amount was dabuled.
