The pie charts above illustrate the percentages of numerous energy producers in one nation during 1983 and 2003.
Overall, limited energy sources such as oil, coal and natural gas account for the majority of generated power, while renewable solutions only take up as much as 27% in 1985 and a quarter of the chart in 2003.
In 1985, more than half of accumulated energy production was attributed to oil, combined with other non-renewable sources such as gas and coal to account for approximately three-fourths of fuel generation. On the other hand, environmental-friendly sources only take up a measly 27%, with nuclear, hydrogen and other solutions coming in 22%, 4% and 1% respectively. This certain direction elucidates a clear preference towards restrictive and pollutant-inducing sources.
Fast forward to 2003, regarding limited resources, oil witnessed a 13% drop, while natural gas saw a 23% increase. In addition, coal also received an increment of 5%, pushing the total proportion of this energy category up to 75%. On the contrary, renewable products decreased by 2%, with various changes within each solution : nuclear energy now only accounts for 5% less, 4% of total energy production was still attributed to hydrogen and other renewables saw a 3% increase.
