As I have discussed many times, overall clean energy investment has been fairly stable since 2011. 2019 is shaping up to be more of the same with overall investment probably declining. There are many competing currents in the clean energy arena and China while committed to some level of clean energy is also strongly committed to coal and is building new coal fired generation at a rapid rate. It's also building substantial nuclear generation.
While climate change activists are ramping up the rhetoric, they are not focused on specific policies to reduce atmospheric CO2 that are politically and economically acceptable. There will be no solution to reducing CO2 emissions until realism rather than wishful thinking prevails.
Despite groundless optimism, current PV is not economically competitive with fossil fuels and as previous posts have emphasized, PV faces significant additional economic hurdles as more of it is installed. Stratosolar represents a path that could solve the mounting problems of PV.
