My favourite source of renewable energy news https://reneweconomy.com.au/ today has a post about the huge amount of solar panels installed worldwide. In March this year there was 1 Terrawatt of solar installed. And this will soon be 1 Terrawat installed each year.
The point out that the cost of wind and solar is such that these energy producers are preferred. Simple economics.
In addition There is an encouraging graph showing the increase in renewables being installed and the decrease in coal fired electricity plants.
