Can everyone help me with my testtt:((?

The pie charts illustrate that which source does electricity came from between 2003 and 2008 in 4 countries (India, Sweden, Morocco, and Vietnam).
Overall, there were many differences between 4 countries in the sources of electricity, In the more developed countries such as Sweden and Morocco, people tend to use electricity from different sources (hydropower) instead of the traditional source (fossil fuel), which is more awful for the environment.
According to the chart, we can see fossil fuel makes up a large fraction of the total (slightly above 80%) while the percentage of Sweden was just 4%, the lowest one. Similarly, the proportion of Morocco is close to the one in Sweden (5%). In Vietnam, fifty-six percent of the sources of electricity produced is from fossil fuel.
We can see from the information, nuclear power accounts for 4% of the total in India. However, this number in Sweden was different a lot, it hit a high point (exactly 44%). And both Morocco and Vietnam didn't use electricity from nuclear power.
And for the last source, hydropower, there was approximately 15% in India. Nearly half of the total in Sweden using electricity produced by hydropower. The highest fraction was in Morocco (95%). Finally, in Vietnam, there was around 45% of the electricity of this country was produced by hydropower.
