Contained in the line graph is information pertaining to the UK's level of

production

of three main fuels from 1981 to 2000. It can

also

be noted that the measurement was Energy Unit (

EU

)

Overall

, it can be seen that Petroleum and Natural gas

then

witnessed an upward trend to exactly 140

EU

in 2000. Regarding Natural gas, its

production

stood at under 40

EU

in 1981 before increasing gradually to approximately 100

EU

in 2000. Turning to the remaining fuel, its

production

accounted for 80

EU

at the beginning before seeing a downward trend to 60
