A line graph illustrates coal and solar capacity, respectively, from 1990 to 2025. Coal peaks around 25,000 megawatts in 1990 and declines steadily starting around 2010 to about 10,000 MW by 2020. Meanwhile, solar hovers below or around 100 megawatts from 2010 to 2020. After 2020, dotted lines for each power source show projected capacity by 2028: Solar climbs to about 7,500 MW, surpassing coal, which by 2028 has declined to about 5,700 MW.
