most opponents of “Planet of the Humans,” Ketan Joshi painted the documentary as “a dumb old bull in the china shop that is 2020’s hard-earned climate action environment.” And along with other critics, he accused the film’s co-producers, Gibbs and Zehner, of wildly misrepresenting the efficiency of renewables. To illustrate his point, he referenced a scene depicting the Cedar Street Solar Array in Lansing, Michigan with flexible solar panels running at 8% efficiency – purportedly enough to generate electricity for just 10 homes. Because that scene was part of a historical sequence filmed in 2008, Joshi dismissed it as an example of the film’s “extreme oldness.” However, this February, the solar trade publication PV Magazine found that Tesla’s newest line of flexible solar shingles had an efficiency rate of 8.1% – almost exactly the same as those depicted in “Planet of the Humans.” While it is true that mono-crystalline solar panels boast a higher efficiency rate (between 15% and 18% in commercially available form), they were also on the market back in 2008. These panels are significantly more expensive than the flexible, less efficient panels, however. And their efficiency levels do not account for the intermittency inherent to solar energy, which does not work well in cloudy or dark conditions. Yet according to Josh Fox, the most vehement opponent of “Planet of the Humans,” the planet-saving capacity of solar and other supposedly clean forms of energy was so well-established it was beyond debate. “The premise of the film is renewable energy doesn’t work and is dependent on fossil fuels. And that is patently ridiculous,” Fox remarked to me. “And the reason why I got into this is because I had young environmentalists – young people who are steadfast campaigners – calling me in the middle of the night, freaking out, [telling me] ‘I can’t believe this!’ And I looked at them and I said, ‘Well, there’s a reason why you can’t believe this; it’s because it’s not true.'” But was the presentation of renewable energy sources in “Planet of the Humans” actually false? Ecological economist William Rees has claimed that “despite rapid growth in wind and solar generation, the green energy transition is not really happening.” That might be because it is chasing energy growth instead of curtailing it. Rees pointed out that the surge in global demand for electricity last year “exceeded the total output of the world’s entire 30-year accumulation of solar power installations.” Are there not reasonable grounds then to be concerned about the practicality of a full transition to renewables, especially in a hyper-capitalist, growth-obsessed economy like that of the United States? A September 2018 scientific study delivered some conclusions that contradicted the confident claims of renewables advocates. A research team measured solar thermal plants currently in operation around the world and found that they are dependent on the “intensive use of materials,” which is code for heavily mined minerals.
