The pie chart compares the percentage of energy consumption based on fuel: specifically, gas, oil, coal, primary electricity, and bioenergy/waste energy over a 10-year period.
Overall, it is evident that the percentage of energy consumption based on gas and coal sources experienced a slight decrease, while the percentage from oil, primary electricity, and bioenergy/waste energy saw an increase.
In 2008, the most popular type of energy consumption was gas, which accounted for 41.3% of the total. Meanwhile, oil energy consumption was the second most popular source at 33.0%. In contrast, the percentage of coal, primary electricity, and bioenergy/waste had the lowest percentages of energy consumption, at 16.9%, 6.2%, and 2.7%, respectively.
By 2018, significant changes had taken place in the percentages of energy consumption by fuel. The share of oil energy rose notably to 35.8%. Likewise, the percentages for primary electricity and bioenergy/waste experienced an increase to 11.6% and 9.1%, respectively. Additionally, the percentages of coal and gas energy saw a slight decline to 39.2% and 4.4%, respectively.
