The pie charts illustrate three sources used to provide electricity – fossil fuel, nuclear and renewable energy – in three different countries, named X, Y and Z.
Overall, fossil fuels were the dominant source of electricity in country X and Y, whereas country Z were largely dependent on renewable energy. Country Y distributed electricity sources much more balanced.
In country X, fossil fuels supplied nearly three-quarters of electricity, at 72 %, followed by renewables and nuclear at 20% and 8% respectively.Despite the balanced energy mix, country Y also relied heavily on fossil fuels, which nearly a half of its electricity. While nuclear accounted for 30% of electricity production, renewables made up a quarter of it, with 25%.
Country Z presented the contrasting pattern, which was significantly dependent on renewable energy to generate electricity at 65%,more than double that of fossil fuels at only 30%. Nuclear made up just 5% of producing electricity, the smallest shares of any sources across three countries considered.
