The pie chart illustrate the percentage of energy generated from six distinct sources- oil, natural oil, nuclear power, coal, other renewable, and hydrogen- in a specific nation in two different years 1985 and 2003. Overall, it is clear that oil remained the primary source of energy production in both years, despite experiencing a notable decline. In contrast, the reliance on natural gas, coal, renewable energy and hydrogen witnessed upward trends, while nuclear power saw a minor drop in its share. Looking first at the dominant energy sources, oil accounted for more than half of the total energy production in 1985, at 52%. However, by 2003, this figure had significantly dropped to 39%, through it still held the largest contributor in 1985 at 22%, also experienced a slight decrease, falling to 19% by the end of the period. Conversely, the proportions of energy generated from alternative sources expanded. The most substantial growth was seen in natural gas, whose share nearly doubled from 13% in 1985 to 23% in 2003, surpassing nuclear power to become the second most important source. Similarly, the percentage of energy produced from coal rose moderately from 8% to 13%. Meanwhile, other renewable energy sources, despite remaining the least utilized, quadrupled from a negligible 1% to 4% over the 18-year period.
