The given two charts illustrate the proportional variations of different resources spent for energy production in a particular country in 1985 and 2003. Overall, there were six main types of supplies for utilization, and the oil was principal source in both years.
In 1985, the fuel of natural gas was used 13%, and by 2003 this usage increased to 23%, which was reached almost equal result with the coal that rose from 8% to 22%. Having used the lowest one, category of other renewables was merely 1% that grew up 4% in 2003.
If we look at the oil, in both of those years it was spent more comparing to others in order to generate energy, despite of being decreased from 52% to 39% in 2003. Similarly nuclear showed 22% in 1985, but in 2003 it had dramatically fell to 8%. In contrast, the utilization percentage of hydro remained same in two-year period (4%).
