The comments from the pro green groups denouncing this film actually prove its authenticity. For example, green groups mentioned in the film claim natural gas and biomass are renewables when they plainly are not, and green criticism of the film cannot attack either of these simple truths.Nor can they deny with credibility the huge money made from renewables through subsidies or that huge population growth and the associated consumerism are causing the planet harm which renewables cannot solve, or the environmental damage caused by renewables depicted in the film. The film is a wake up call and very worthwhile viewing.
