“ And solar was the fastest-growing electricity source for the 20th year in a row.

It now provides 7% of the world's electricity”

Exponential growth is unintuitive. More than a full percentage point was added last year and that will continue to accelerate. Even the IAE is predicting 14% share by 2030 and they have underestimated solar for the last 10 years now

Not everything that grows quickly is exponential. What evidence specifically do you have that the growth is proportional to the already existing capacity? Or even that it will continue to accelerate?

A counterpoint: the recent quick growth has been fueled by panels getting cheaper. They used to be the majority of the cost. But that's not true anymore. The cost will soon be mainly installation (i.e. labor) and space. Neither are amenable to drastic further decreases.

Fortunately we've already reached the point where it's the cheapest option, so that it will continue to replace other power sources even if it does get much cheaper anymore.
