There is a widespread misperception that "biomass" = "waste" wood. But entire forests are being consumed. Also, The biomass industry is able to function only because it receives huge government subsidies, without which it would be economically unfeasible. This is true both in the U. S. and Europe. This is based on the fiction that biomass is carbon neutral, and thus a "green" alternative to fossil fuels, like wind and solar. But in reality, burning wood releases as much or even more carbon than coal. In theory, the tree you cut down would eventually have died and decayed and been replaced by another tree. It is a "renewable" resource. But that takes a long time and global warming is now. The planet needs more trees to sequester existing carbon, not fewer.
The film sparked a heated discussion with the filmmakers afterward. It is a discussion that needs to take place all over the world .
