Figure 2 |. Age structure of global electricity-generating capacity.
The operating capacity of gas- and oil-fired electricity-generating units (a) and coal-fired units (b) where the youngest units are at the bottom. Lighter shaded bars at the bottom show proposed electricity-generating units according to the year they are expected to be commissioned. Recent trends in Chinese and Indian coal-fired units (red and orange at lower right, respectively) and U.S. gas-fired units (green at left) is apparent. Note that 0 years old means the power units began operating in 2018.
