The pie charts illustrate the percentage of energy generated from various sources in a specific country from 1985 to 2003. It is evident that the usage of some energy sources increased over time, while others experienced a decline.
Throughout the entire period, oil remained the primary source of energy production, although its contribution decreased from just over half (52%) in 1985 to approximately two-fifths (39%) in 2003. Additionally, the use of nuclear energy also saw a decline, dropping from 22% to 17%.
In contrast, the utilization of natural gas and coal experienced growth, rising from 13% and 8% in 1985 to 23% and 13% respectively by 2003. Interestingly, the share of energy produced from hydrogen remained stable at 4%, while energy from other renewable sources increased from 1% to 4% over the 18-year period.
In summary, the largest portion of energy production came from oil, while the smallest shares were from hydrogen and other renewable sources during the years from 1985 to 2003.
