The bar chart compares the energy production from different resources in 1985 and in 2003. Overall, energy produced from Natural gas and Coal increased significantly, while that of from Oil – the most heavily reliant up on energy source in both years- and nuclear dropped considerably. In the meantime, being the least used energy sources, hydro and other renewable alternatives experienced negligible rise or no change over time.
Focusing on energy sources with significant upward production trends, Natural gas had 13% of energy production in 1985, higher than that of Coal energy with 8%. However, by 2003 both energy resources had drastically risen to producing quite similar percentage of energy, with the respective figures of 23% and 22%.
Meanwhile, despite remaining the most demanded energy source in 1985 and in 2003, Oil production illustrated a heavy drop from 52% to 39% in the given period. It is also noteworthy that Nuclear energy production had quite similar in magnitude drop, with 22% in 1985 to mere 8% in 2003.
While other energy resources were experiencing dramatic changes in energy production percentage, Hydro energy sources remained only 4% of energy production in both years, compared to little increase of 3% in alternative renewables.
