We have an aging fleet of power plants:
- 51% of all generating capacity is 30+ years old.
- 73% of all coal plants are 30+ years old
- 24 out of 25 oldest plants (60+ years) are hydropower
- Nearly all nuclear plants are 20+ years old
Notice that hydropower was the first energy source built, the creation of coal plants dominated from 1950 to the mid-80s, and it’s been all natural gas since then 플래시 플레이어 디버거 다운로드.
