The given pie chart illustrates how the percentage of energy generated from various sources in a country changed between the years 1985 and 2003. Overall, while the energy received from the nuclear source rose dramatically, the indicator for the coal decreased significantly.
In 1985, the oil was considered the majority of production at 52%(about half, over half) in primary energy resource. In 1985, nuclear power was considered one fifth of the total energy output, making it the second-largest energy source after oil. By 2003, the figure for this category had altered , reaching 8%.
in contrast, coal energy experienced noticeable growth. In 1985, coal accounted for just 8% of energy production. By 2003, this figure roughly tripled to 22%. This rise suggests that coal became a much more important contributor to energy generation, due to increased availability compared to other sources.
In 1985, other renewable energy resource was witnessed the lowest indicators, whereas increased slightly in 2003. The ratio for the hydro source remained the stable in both years . By 2003, the second portion of energy production constituted natural gas and became the third biggest energy source.
