A few days ago, Emily Atkin posted a reaction to Michael Moore’s latest film, Planet of the Humans (directed and narrated by Jeff Gibbs), in which she began by admitting that she hadn’t seen the film yet. When writers take that approach, you know there’s already blood in the water. (She has since watched the film and written an actual review. Full disclosure: I’m in the film, included as one of the “good guys.” But I don’t intend to let that fact distort my comments in this review.)
The film is controversial because it makes two big claims: first, that renewable energy is a sham; second, that big environmental organizations—by promoting solar and wind power—have sold their souls to billionaire investors.
I feel fairly confident commenting on the first of these claims, regarding renewable energy, having spent a year working with David Fridley of Lawrence Berkeley National Laboratory to assess the prospects for a complete transition to solar and wind power.
We found that the transition to renewables is going far too slowly to make much of a difference during the crucial next couple of decades, and would be gobsmackingly expensive if we were to try replacing all fossil fuel use with solar and wind. We also found, as the film underscores again and again, that the intermittency of sunshine and wind is a real problem—one that can only be solved with energy storage (batteries, pumped hydro, or compressed air, all of which are costly in money and energy terms); or with source redundancy (building way more generation capacity than you’re likely to need at any one time, and connecting far-flung generators on a super-grid); or demand management (which entails adapting our behavior to using energy only when it’s available).
