Great quote from @shellenberger: “A gallon of jet fuel contains 34 kilowatt-hours of energy in a package weighing six pounds. A lithium-ion battery storing the same energy weighs 250 pounds. That density gap is why every military on earth runs on liquid hydrocarbons, why every container ship crossing the Pacific burns bunker fuel, why every combine harvester in Iowa runs on diesel, and why every 747 landing at Heathrow runs on kerosene. The fact that nobody wages war over solar panels is evidence of their limitations not superiority.” Bottom Line: The laws of physics and thermodynamics are laws, not mere suggestions.
