To begin, the percentage of energy created from oil was 52% in 1985, while it was declined and reached at 39% in 2003. Moreover, the most energy produced from nuclear at 22% in 1985. But it fell down to 17% in 2003. Furthermore, comparing other sources like coal, nitrogen gas and other renewable, we can observe that they rocketed in 2003 and their percentages are 13%, 23% and 4%.
