The line graph illustrates the comparison of European country in terms of their contribution to the production level of main .The data measured in tonnes and includes the Petroleum,Coal,and Natural Gas.
Overall , the consumption of petroleum products has the highest impact while, the Coal Industry fluctuating and dropped by ends of the period .Natural gas production was remind steadily and the value was go up over the last four years.
At the beginning of the period ,Petroleum production was at 100 tonnes and increased to around 125 tonnes in year of 1983 to 1986. In 1987 , showed a dramatically decreased rate reneging between 100 to around 70 tonnes. Again the price rose in 1991 with 120 tonnes until reaching a peak in 1998 with 139 tonnes and reported slightly declined by the ends of period with 120 toons.
Over the first four years, The Coal gases level was 80 tonnes and dropped to about 45 tonnes in 1995 and increased to around 70 tonnes in 1987. In contrast, the Coal Power saw a significant decreased output in 1990 with 60 tonnes and declined to 40 tonnes in 2000 .
Natural Gases, which is used in industrial production and Transportations services was remained steady at 40 tonnes over thirteen years and increased by ends of the period reaching to around 82 tonnes.
