“The 2022 report is the 17th consecutive edition and provides proof of what experts have been warning about: the overall share of renewables in the world’s final energy consumption has stagnated – rising only minimally from 8.7% in 2009 to 11.7% in 2019 – and the global shift of the energy system to renewables is not happening.”
This is a really good report, Bob, thanks for posting. Here is the summary document for policy makers, for those who want more info than in the press release without too much detail: https://www.ren21.net/wp-content/uploads/2019/05/GSR2022_Key…
The report covers ALL energy use, not just electrical power production, hence the very slow growth of renewables as a percentage of total energy use. We have a long, long way to go to make serious dents in some of these categories, but we have the technology to make huge strides, and it’s generally already affordable, if you can swing the capital cost and amortize over 10 years.
Government policies that explicitly or implicitly subsidize fossil fuels are the biggest barrier to making faster progress.

My pleasure.

That is the most important number of course. Well, maybe the GHGI (greenhouse gas index). https://gml.noaa.gov/aggi/
Between 2011 and 2021 the forcing went from 2.83 to 3.22 W/m2, a 14% increase.

It should also be noted that of the 12.6% that renewables represent, the largest segment is biomass burning (including ‘traditional’ in third world countries) which is the topic of considerable discussion as to how green it is. The second largest category is large hydro which some environmentalists dislike. Solar and wind make up 2.8% of global energy production and are included in “other”.
