That has to be the most detailed (yet still legible) and informative graph I have seen in a very long time. Thanks. I had never heard of the National Renewable Energy Laboratory https://www.nrel.gov/ https://www.nrel.gov/ before.

Presumably other areas of the world have their own centres of research.
