The charts show changes in the share of energy produced from various resources in a country in 1985 and 2003.
Overall, it is plain to see that the proportion of oil and nuclear energy showed a decrease; meanwhile, natural gas and coal demonstrated an upward trend. During this period, however, the production of hydro energy remained unchanged in both years. It is noteworthy that the proportion of oil production remained the biggest one in both years; however, the smallest one was other renewable energy.
In 1985, the largest energy producer was oil, accounting for 52 percent. However, the second largest energy producer was the nuclear sector, making up 22 percent, whereas natural gas comprised just 13 percent. The coal category represented only 8 percent; meanwhile, hydro and other renewable energy showed relatively similar proportions with only 4 percent for hydro energy and only 1 percent for other renewable energy.
By 2003, the share of oil production dropped from 52 to 39 percent. Natural gas’s proportion went up from 13 to 23 percent. In the meantime, coal’s output almost tripled from just 8 to 22 percent, whereas nuclear’s energy production showed the opposite trend, dropping from 22 to just 8 percent.
Hydro’s share remained unchanged; meanwhile, other renewable energy’s share rose from 1 to 4 percent.
