The pie charts illustrate the proportions of electricity generated from fossil fuels, hydropower, and nuclear power in four countries between 2003 and 2008.
Overall, it is clear that fossil fuels were the main source of electricity in India and Vietnam, whereas nuclear power and hydropower dominated in Sweden and Morocco respectively.
In India, the vast majority of electricity came from fossil fuels, accounting for 81.9%, while hydropower contributed 14.6%. Nuclear power made up only 3.5%, which was the smallest share in this country. Similarly, in Vietnam, over half of the electricity (56.3%) was produced from fossil fuels, and the remaining 43.7% came from hydropower, as there was no nuclear power generation.
In contrast, Sweden relied mainly on nuclear power, which represented 44% of its electricity production, followed closely by hydropower at 52%. Fossil fuels contributed just 4%. Morocco, however, depended almost entirely on hydropower, making up 95.5% of its total, while fossil fuels accounted for only 4.2%.
