The given figure illustrates the electricity percentage produced by various resources between the years of 1987 and 2019.
Among these 7 sectors, only 2 of them, red and purple, could increase their percentage at the end of the period, while the rest of them have declined in their production. The purple line stayed constant in the first years until it started to rise in 1995. The line increased significantly over the past few years, then it faced some unstable situations, but it could make a 10% incrase in 2019 compared to 1987. The red line, on the other hand, has also created a 10% increase with slight improvements each year. This sector had never endured a deep decline during this period. The next 2, which are dark blue and gray, have kept their average productions even though they have faced plunges. Among the last 3, green has the greatest decrease, which is arund 8%, while yellow and light blue dropped only 5%.
Since the graph’s description is not written in English, I was not able to name the resources; however, I can assume these are the most common sectors, such as renewable energy and gasoline.
