The pie chart provides information about the percentage of various types of energy sources in 2014 and 2018. Overall, while the proportion of renewable energy sources experienced an upward trend, the opposite was also true for coal and nuclear. Additionally, the figure for gas and oil and other energy sources remained stable, with the former being the highest share of all throughout the period.
Focusing on the larger figures, starting at 30.1 in 2014, the share of gas remained unchanged by 2018, making it the largest figure in every period. A considerable rise was observed in the proportion of renewables contributing to the energy production, reaching 26.2% from 15%. However, there was a subtle drop in nuclear energy’s share from 22.5% to 21.6% between 2014 and 2018.
In contrast, the proportion of coal that contributes to the generation of energy started at 28.4% in 2014, a figure that then saw a noticeable decline to 18.1% over the span of 4 years. Meanwhile, the percentage of oil and other energy sources remained stable at 4%, making it the lowest share across the period.
