Electric Propulsion's Dirty Secret: Why Lithium Can't Fly (Or Float) Profitably (kumarletter.com)
Lithium propulsion for aircraft and boats is fundamentally unprofitable across the entire U.S. grid. The numbers don't lie: 60× worse energy density than jet fuel, 3.3× higher operating costs, 22% reduced asset utilization, and payback periods that consume 2/3 of the asset's lifespan. Anyone claiming otherwise is ignoring basic physics or hiding most of the energy and economic costs.

Will Peak Demand Roil Global Oil Markets? (newyorkfed.org)
"Peak oil”—the notion that the depletion of accessible petroleum deposits would soon lead to declining global oil output and an upward trend in prices—was widely debated in the late 1990s and early 2000s. Proponents of the peak supply thesis turned out to be wrong, given the introduction of fracking and other new extraction methods.
