The amount of gas experienced the highest production level among others, with 29,63% and 30.39%, however, the percentage of others category showed by far the lowest group (4,92% and 3,98%) in both years. Meanwhile, the production of petro was decreased from 29,27% in the starting year to 19.88% in the end of the period, while the nuclear production witnessed an increase by almost 5% over the decade. Although, the letter highest proprotion of energy production was seen in coal group, with 29,83 % in 1995 and 30,93% in 2005.
