The given line graph shows the production levels of three main types of fuel (petroleum, coal, and natural gas) in a particular European country, from 1981 to 2000.
Overall, it can be seen that petroleum was by far the most produced type of fuel, while the amount of natural gas being produced was increasing rapidly.
In 1981, the amount of petroleum being produced was around 100 tonnes. It increased steadily over the next few years to reach around 130 tonnes prior to dropping back to just under 100 tonnes in 1989. It then rose up again to around 130 tonnes in 1995, where it fluctuated slightly until the end of the period.
Coal was the second most-produced fuel in 1981, at 80 tonnes. Coal production remained constant until it dropped suddenly down to around 50 tonnes in 1985. It rose back up to merely over 70 tonnes in 1987 prior to slowly declining over the next 13 years to merely under 40 tonnes. The production of natural gas remained unchanged at about 40 tonnes until around 1991 when it began to rise exponentially.
