wind, solar, batteries, geothermal, tidal, etc combined could never keep up with global energy demands
This is false. Solar alone is more than enough energy. An hour of solar energy is equal to current global annual energy consumption. Two months of sunlight incident on land (assuming 5 hours of sunlight a day on average, at 1kw per square meter) amounts to more energy than remains in fossil fuel reserves.
If anything, though, this is an even worse indictment of capitalism than the idea that current energy usage is unsustainable--we could be powering our society in a way that doesn't wreck the entire planet, but we don't because it's cheaper not to.
