I think that the author is engaging in a bit of knit-picking with another anti-capitalist writer, Hamza Hamouchene, but nevertheless the former does focus on the immediate issue of reducing fossil fuel emissions without neglecting the ultimate agenda: the urgent necessity of replacing private control of economies under capitalism with social control of economies under some form of socialism.
While ecosocialist class struggle is still too weak to prevent the deficiencies in these big solar projects, and as the global climate and energy justice movement gains strength, then the opportunity to create a sustainable and just solar transition will grow. But the creation of a wind/solar energy infrastructure should be welcomed now even with all the problems pointed out by Hamouchene. We cannot wait for the end of the rule of capital to start building this renewable infrastructure; it will be too late.
