The given pie chart illustrates the percentage of production of different resources (oil, natural gas, coal, nuclear, hydro, and other renewable) in a nation between 1985 and 2003.
Overall, oil resources accounted for the highest amount in both years, followed by natural gas, coal, and nuclear. However, hydro and other renewable were less produced than the others.
Initially, oil production accounted for 52% in 1985 and 39% in 2003, the figures were the highest in both years. Following that, there were only 13% of natural gas items were produced in 1985, while the figure in 2003 was higher by 10%. Coal production, the third-highest productions’ resources, in 1985 accounted for 8% and up to 22% in 2003. Besides, the proportion of nuclear items was 22% in 1985 and only 8% in 2003.
On the other hand, hydro-energy production accounted for 4% in 1985 and remained the percentage in 2003. Other renewable production only accounted for 1% in 1985, however, the figure was up to 4% in 2200. Both of energy-resource productions were the lowest in both years among the other four-energy production.
