The provided line graph compares a production rate of various fuels in UK between 1981 and 2000
Overall, what stands out is that the amount of production Petroleum and Natural gas are increased through out given perod. While reverse could be said about Coal. Of paricular note is that petroleum remained the most produced fuel
Focusing on upward tends first, Petroleum had a rapid growth from 94 to 140 energy units in between 1981 and 1984 and save stability to 1984. However it saw a sharp decrease to 100 in 1990. Over a period of 5 years it had a stable increase followed by a period of stability. In stark contrast, natural gas production showed a stable growth from 38 to 100 between 1981 and 2000 without any significant dips.
Turning to the coal had stbility of 80 energy units from 1981 and 1984. But Coal saw a sharp decline to 37 and a significat increased to 60 nad remained stablility to 1989. Yet it has a constant fall to 2000
