Do none of the commenters (or the OP) want to acknowledge that this a graph of the *SHARE* of generation and not the absolute generation? Nuclear energy, for example, generates roughly as much today on a global basis as it ever has
In terms of share of global electricity output, coal peaked in 1905.
Hydro peaked 100 years ago. Oil before the, well, oil crisis.
Nuclear peaked in the 1990s and gas, maybe, has just passed its peak.
And then there is the yellow line...
