The pie charts compare the sources of electricity production in four countries – India, Sweden, Morocco and Vietnam – over the period from 2003 to 2008.
Overall, hydropower was the dominant source of electricity in India, Morocco and Vietnam, whereas Sweden relied primarily on fossil fuels. In addition, nuclear power contributed a small proportion of electricity generation only in Sweden.
In India, electricity production was overwhelmingly dependent on hydropower, which accounted for 92% of total output. Fossil fuels made up the remaining 8%. A similar pattern can be seen in Morocco, where 91% of electricity was generated from hydropower, while just 9% came from fossil fuels.
Vietnam also relied heavily on hydropower, although to a lesser extent than India and Morocco, with 75% of its electricity produced from this source. The remaining 25% was generated from fossil fuels.
By contrast, Sweden displayed a more balanced energy mix. Fossil fuels were the largest source, contributing 50% of total electricity production. Hydropower accounted for 46%, while nuclear power made up the remaining 4%, representing the only instance of nuclear energy use among the four countries.
