There is a LOT in that film to cover. I wanted to address a specific slice that I felt had not been fully addressed elsewhere. If you want a deeper dive into the critique of the science of POTH I will recommend the reviews I mentioned at the top.
TLDR: Modern biomass is pretty bad. If it is better than coal/natural gas, it is not by much. That, and the issues with corporate capture of the biomass area is pretty bad. That being said, most environmental groups stopped promoting biomass 5–10 years ago, so the specifics of the critique of biomass in POTH is a bit weird.
Solar and wind are significantly better than what the film implies. Strongly recommend those other reviews to get the details there.
