So where are the battery electric trucks?

Heavy-duty diesel-engine trucks (agricultural, cargo, mining, logging, construction, garbage, cement, 18-wheelers) are the main engines of civilization. Without them, no goods would be delivered, no food planted or harvested, no garbage picked up, no minerals mined, no concrete made, or oil and gas drilled to keep them all rolling. If trucks stopped running, gas stations, grocery stores, factories, pharmacies, and manufacturers would shut down within a week.
Since oil, coal, and natural gas are finite, and biomass doesn’t scale up, clearly someday trucks will need to run on wind, solar, hydro, and geothermal generated electricity. Yet even batteries for autos aren’t yet cheap, long-lasting, light-weight, or powerful enough for most Americans to replace their current gas-guzzlers with. And given the distribution of wealth, few Americans may ever be able to afford an electric car, since two-thirds of Americans would have trouble finding even $1,000 for an emergency.
