Q: How sustainable are so-called "renewable" energy sources?
A: Not necessarily as sustainable as their enthusiasts would like to think, it seems (Bllomberg News headline from February 5, 2020: "Wind Turbine Blades Can't Be Recycled, So They're Piling Up in Landfills")
Instapundit flagged this recent Forbes article by wondering when filmmaker Michael Moore (yes, that one) had been "red-pilled."
I don't trust Moore, whose last honest film in my opinion was Roger & Me (1989), but he may have had an epiphany:
"The main problem with biofuels—the land required—stems from their low power density. If the United States were to replace all of its gasoline with corn ethanol, it would need an area 50 percent larger than all of the current U.S. cropland.
Even the most efficient biofuels, like those made from soybeans, require 450 to 750 times more land than petroleum. The best performing biofuel, sugarcane ethanol, widely used in Brazil, requires 400 times more land to produce the same amount of energy as petroleum."
