The IEA is still way behind the curve, though not as much as it used to be. But even behind the curve of reality, it is giving us serious Good News. Cue wailing, rending of garments, and gnashing of teeth. (Come to think of it, I'd like to see that.)
According to the International Energy Agency’s (IEA’s) World Energy Outlook 2019, solar photovoltaic (PV) is set to become the largest source of installed electrical capacity in about 2035, if countries pursue policies as planned. By 2040, solar could make up 24% of global installed capacity—up from 7% in 2018—but its share of generation could hover around 11%, up from 2% in 2018. In regions like China, solar could overtake coal in the power mix by the mid-2020s. The IEA’s projections for solar’s explosive growth are one of the largest differences between the current report and its 2018 edition.

You see? And these are not new ideas.
