The given pie charts illustrates percentage of energy generated from various resources between year 1985, and 2003 in a particular country.
From the overall analysis, it can be observed that production of energy from oil and nuclear decreased that of generated from natural gas, coal, and other renewable resources increased over the years.
After scrutinizing at the detail , it is readily apparent that in the year 1985, 52% of energy was generated from oil and only 13% was from natural gas. After 18 years , the production of energy from both these resources shown opposite trend while energy making from oil dropdown to 39% , from natural gas it inclined to 23% . Power production from coal increased from 8% in 1985 to 22% in 2003. On the other hand , power generated from nuclear was 22% in the year 1985 which get declined to 8% after approximately two decades.
Probing further , it can be noted that energy making from hydro stood at 4% and remain same over the years. Finally , power generated from other resources was only 1% in initial year and reached to 4% in the year 2003.
