The four pie charts illustrate a trio of production sources of electricity in four nations located around the world between 2003 and 2008.
Overall, fossil fuel is most commonly used in Asian countries, whereas hydroelectric power is mainly used in the remaining two nations. On the contrary, the least ubiquitous is nuclear power, as it was merely utilized widely in Sweden.
Looking at the charts more closely, one can see that fossil fuel dominated greatly over other sources in India and Vietnam, at 82% and 56%, respectively. It was followed by hydroelectric, which plays a more pivotal role in Vietnam than its Asian counterpart, taking up almost half of the proportion while in India, its percentage remained at 14%. On the other hand, Morocco experienced the opposite, while hydropower produced 95% of electricity, fossil fuel only filled up the remaining percentage. Similarly, more than half of Sweden’s electricity is produced using hydropower, and only 4% was made by fossil fuels whereas nuclear power took up 44%. In comparison, India also used nuclear power despite the fact that it only made up to 4% of the total amount of electricity.
